Symptoms:

The tell-tale error is that Aurora will not start, instead giving the error Could not create the Java virtual machine.

If your computer has enough memory, but is near the limit, it is also possible that Aurora will start, but the GUI

will look strange (scroll bars won't display properly, text will get dropped, etc.).

Requirements

This Server has only been tested on Windows XP, Windows Vista & Windows7, runningJava 6 (Also referred to as 1.6) I.e., the latest version of Java. (Aurora-CCPM shouldrun with many earlier version of Java also as long it is Java 5 or newer)

To determine the version of Java being run on your WIndowsXP computer, from theStart menu on the desktop, select the Run option, in the Run dialog type cmd. Thiswill open an command window. In the command window type Javaversion. Thisshould respond with either no version of java installed or something similar to Java(TM)2 Runtime Environment, Standard Edition (build 1.5.0_11-b03), Java HotSpot(TM)

Client VM (build 1.5.0_11-b03, mixed mode, sharing).

If the version number is 1.5 or something higher, Proceed to the next section, "StartingAurora-CCPM"

Else if the version number is NOT 1.5 or higher, you may still have the correct version ofJava installed. To check, go to the Start menu on the desktop, select the ControlPaneloption, then select Add or Remove Programs Under the Currently installedprograms. Look for items that start with J2SE Runtime Environment 6.0 or Java(TM) 6.

If you still don't have Java, then,

1. Download the latest version of Java fromhttp://www.java.com/en/download/2. Install Java by opening the downloaded file.3. Following the instructions provided by the Java installer and select all the default

options.4. At some point during the installation all browsers will need to be closed.5. Reboot you computer, after the reboot open this web page again and you should be able

to launch Aurora

Troubleshooting

Verifying Java WebStart

The links below allow you to test your computer and your browser's compatibility withJava WebStart. Follow the links in order. If the first tests work, continue testing with themore complex examples that are larger and closer to Aurora in size.

http://www.java.com/en/download/help/testvm.xml

http://www-pw.physics.uiowa.edu/das2/javaPlatformTest.jbf.html http://java.sun.com/javase/technologies/desktop/javawebstart/demos.html

https://j3d-webstart.dev.java.net/test/

Webstart works but Aurora does not

If the above tests show that Java WebStart works in general, but you are still havingtrouble launching Aurora, please try the following:

1. Display the Java Console.

Helpful information is displayed in the Java Console, if it enabled. To enable go into theJava Control Panel, and click on the Advanced tab. Enable the option according to thescreenshot below.
http://www.java.com/en/download/help/testvm.xmlhttp://www.java.com/en/download/help/testvm.xmlhttp://www-pw.physics.uiowa.edu/das2/javaPlatformTest.jbf.htmlhttp://www-pw.physics.uiowa.edu/das2/javaPlatformTest.jbf.htmlhttp://java.sun.com/javase/technologies/desktop/javawebstart/demos.htmlhttp://java.sun.com/javase/technologies/desktop/javawebstart/demos.htmlhttps://j3d-webstart.dev.java.net/test/https://j3d-webstart.dev.java.net/test/https://j3d-webstart.dev.java.net/test/http://java.sun.com/javase/technologies/desktop/javawebstart/demos.htmlhttp://www-pw.physics.uiowa.edu/das2/javaPlatformTest.jbf.htmlhttp://www.java.com/en/download/help/testvm.xml

2. Clear the browser cache

The browser cache is the location on your hard disk where Web pages and files (suchas graphics) are stored as you view them. This speeds up the display of pages youfrequently visit or have already seen because Internet Explorer can open them fromyour hard disk instead of from the Web.

When you first try to access Aurora, you may encounter Java Web Start errors such ascannot find the file specified or Unable to launch the specified application. Theseerrors may be related to information stored in the browser cache. You can overcomethese errors by emptying your browser cache.

To be safe, perform the next step before trying Aurora again.

3. Clear the Java Web Start Cache


5/162

Click on Java under Windows Control Panel.

Then go to Settings under Temporary Internet Files on the first tab. (The followingscreenshots are for Java ver. 1.6)


6/162

Once there, click on the "Delete Files..." button

In the next screen, click "Ok" to delete the temporary files. Your Java Web Start cacheis now empty.

At this point, try launching Aurora again.

3. Using Aurora from Behind a Proxy Server/Firewall

Java Web Start software must be configured with the correct proxy settings in order tolaunch applications from outside your firewall. Java Web Start software willautomatically try to detect the proxy settings from the default browser on your system.Java Web Start technology supports most web proxy auto-configuration scripts. It candetect proxy settings in almost all environments.

If the proxy settings are not correct, a typical error is "Cannot Load Resources."


7/162

If the proxy setting cannot be automatically detected, then you will need to set themmanually:

1. Go to the Java Control Panel. This is accessed by going to the Control Panel -> Java2. On the first tab of the Java Control Panel, click on Network Settings.

Change to "Direct Connection." This helps to clear any confusion the proxies may havein the later stages of the startup.

Finally, if the above does not work, then uninstall Java 6 andinstall Java 5instead, as Java

6 has stricter security settings by default and that may be causing conflicts.

Using a basic template to create a new scheduleGetting started with Aurora can be a little confusing at first. This tutorial will show you how to usea basic template to create a simple schedule. Once you learn how to create a simple schedule,you will have the basic understanding to create as complicated a schedule as you require.The basic steps are as follows:

oDownloadthe template with one pre-loaded ActivityoCopy the sample Activityto create as many Activities are you requireoAdd constraintsto establish the relationships (predecessor and successor) between

ActivitiesoAdd Resource Requirementsto your ActivitiesoSchedule your networkusing Aurora

Lets get started. Download theBasic Template (Basic Template.cmp)file by right-clicking on the linkand selecting Save Link As and load it into Aurora (File menu -> Open). Ensure that theextension on this file is .cmp when saving. When you open this file, you will notice that there is a new project called Basic Template withone Activity under it.

8/162

What we will be doing in this tutorial is creating new activities and establishing constraints onthem to create a simple schedule. We will use the first Activity (labeled with a 1 in the screenshot above) and will copy it to create a sample network. We will create all the Activities that weneed first (9 total) and then we will build the relationships between them. Activity 1 will be thestarting node and Activity 9 will be the ending node. Neither of them will have any time duration,as they are simply the nodes where the projects begin and end. Only the Activities between themwill have time durations.Click on the Activity to highlight it and press the copy button at the bottom of the left-hand pane.


9/162

After you press the Copy button, Aurora will create a new Activity that is identical to the originaland the screen should look like this when you click and highlight the new Activity.


10/162

You can now change the name and IP Number to be T1 and 2 as shown below:


11/162

Go to the Schedule Attributes tab in the middle pane and change the Active Duration to 1440minutes.


12/162

Then, go to the Duration Info tab, and change the value for Safe Duration to 1440 minutes, andthe Aggressive Duration to 720 minutes.

You may now continue in this manner to create more Activities. For this exercise, you will need tocreate a total of 9 Activities with the following durations:

Activity # Name IP NumberActive and Safe

DurationsAggressive Duration

1 T0 1 0 02 T1 2 1440 720

3 T2 3 2880 14404 T3 4 5760 28805 T4 5 4320 21606 T5 6 1440 7207 T6 7 7200 36008 T7 8 4320 21609 T8 9 0 0

The first two columns (Name and IP Number) will be entered in the Properties tab in the middlepane. The durations will be entered in the Schedule Attributes tab in the middle pane.Once you have created all the Activities, your window should look like this:


13/162

Add Constraints to your scheduleNow we are ready to add some constraints (predecessors and successors) and make this lookmore like a schedule than a set of tasks.

Constraints are added by clicking on the Activity in either the left- or right-hand pane and thenclicking on the Constraints tab in the middle pane. Lets start with Activity 1. We would likeActivity 1 to be the predecessor to Activities 2, 3, 4, and 5. The easiest way to set constraints is toclick on the Predecessor and then add in the Successors using the Constraints dialogue.Click on Activity 1 in the left-hand pane and then click on the Constraints tab in the middle pane.Again, highlight the activity in the middle pane and click the Add button to open the ConstraintsWizard dialogue.


14/162

You will notice that Activity 1 is not selectable and is marked in red; this is because you cannotadd a constraint that loops back onto itself. What you want to do is select Activity 2 and then clickthe Next button.


15/162

This will bring us to the second page of the Constraint Wizard, that will ask you to define therelationship between the two constraints you have chosen (Activity 1 and Activity 2).


16/162

The first property in this new display (below the constraint type combo box) allows you to selectthe temporal constraint type. The default Normal selection indicates that this temporal constraintrelates the start or end time of the first activity to the start or end time of the second activity.Selecting Normal in the temporal constraint type combo box enables the activity relationshipproperty combo box directly below it, by default set to Finish


17/162

Now, go back to the left panel, and select Activity 2, then under the Constraints tab, you will seethat it has a Predecessor of Activity 1.Click on the Add button.

Select Activity 6 in the next screen, and hit Next.


18/162

In the next screen, create a constraint so itll look like the diagram below:

You will want to continue in this way to create constraints for every activity following the layout ofthis diagram:


19/162

When you are done, your PERT display may look crowded and you may want to rearrange the

display by pressing (auto-arrange) in the bar above the right-hand side panel. You can then

press (auto-fit) to fit the elements to the display size.You should get something similar to this view when you are finished:

Adding Resource Requirements to Your ScheduleIn the sample schedule that you have created so far, you have created Activities and establishedthe relationships between them. Now, you can go back to the individual Activities and addResource Requirements.In the left-hand panel, click on Activity 2. In the middle panel, click on the Requirements tab.Once youre there, click on the Add button to open the dialogue box. For this sample schedule,

we are going to use the A set of Requirements for all the Activit ies that require resources(Activities 2 through 8).


20/162

Once you hit ok from this dialogue box, you will have added a resource requirement. You will nowsee an added line in the Requirements tab that should look similar to below:


21/162

Depending on the Activity, you may need to change the quantity required. In this case, however,for Activity 2, we can leave the quantity at 1 and continue. You will need to add resourcerequirements to Activities 2 through 9 according to the following table:

Activity # Resource Set Quantity Required

2 A set 13 A set 24 A set 25 A set 26 A set 27 A set 18 A set 2

The reason why we do not add Required Resources to Activities 1 and 9 is because they functionas milestoneendpoints for our schedule. You will also notice that both Activity 1 and 9 have a

duration of 0 minutes. This is also due to the fact that they are milestones and are merely astarting and ending point for the schedule.

Using Aurora to ScheduleBefore we schedule the network, we will need to update the settings in Aurora. These settingsmay need to be changed each session, since they will not be saved into your file.Open the Schedule settings by going to the file menu: Schedule -> Settings


22/162

In the dialogue box that appears called Scheduler Settings, you will want to highlight thescheduling parameter: Critical Path Prioritizer and click the up arrow 5 times to move it to thetop of the list. Then click Close at the bottom of the dialogue box.


23/162


24/162

Access the Schedule function by again going to the file menu: Schedule -> Schedule

This will bring up another dialogue box. You want to select Safe and check the box for ShowSummary Report when Scheduled and hit OK.


25/162

Aurora will now schedule the project and provide a Scheduling Summary Report window and aPre-Schedule Analysis Problem Report window. If you have made the network as describedabove in the tutorial, you should see a Summary Report similar to this:

You can now close the Scheduling Summary Report window and the Pre-Schedule AnalysisProblem Report windows.To see the schedule in Gantt Chart form, you can go to the Display menu and select Display ->Gantt Chart.

Gantt Chart

The Gantt chart (based on a design developed by Henry Gantt in 1910) plots activities in a schedule by

the temporal order in which theyll be carried out. The X-axis represents time (increasing from left to

right), and activities are drawn as rectangles with start points and lengths corresponding to their start

dates and completion times respectively. Activities that overlap in time (i.e. activities that occur

simultaneously for some or all of their duration) are stacked vertically, leading to a general trend (with

the default display settings) of activities being drawn from the charts upper-left towards its lower-right.

To access the Gantt Chart display in Aurora click on the Displays menu -> Gantt Chart as shown below.

28/162

You will notice that Aurora will create different tabs across the top bar as you open more windows. Use

these tabs to switch between the different displays. The Edit tab is where you created the schedule

parameters and where you can edit them as needed.


29/162

To rename or close these tabs, right-click on the tab you wish to close and you can choose to Rename or

Close the selected tab.

Resizing the View

To zoom in and out of the view, place your mouse either above the chart display in the date section, or

to the left of the chart (the areas designated in red in the following screenshot), click and drag to resize.

These slider bars will only appear after you have clicked in the area above or to the left of the Gantt

Chart and will disappear after you are done resizing your chart. You can see these bars in action in the

following shortGantt Chart Video.
http://www.stottlerhenke.com/products/aurora/tutorial/9_GanttChart.swfhttp://www.stottlerhenke.com/products/aurora/tutorial/9_GanttChart.swfhttp://www.stottlerhenke.com/products/aurora/tutorial/9_GanttChart.swfhttp://www.stottlerhenke.com/products/aurora/tutorial/9_GanttChart.swf


30/162

In the Gantt Chart view, there are several buttons that may help you view your schedule more

efficiently.

-- Shows a legend for the plot elements and constraints

This button will toggle the Legend for the Gantt Chart. The Legend window can be moved around by

clicking and dragging the title bar.

-- Configure how constraints are displayed

This button will bring up the Constraint Display Configuration window.


31/162

Clicking Show all constraints will link the tasks together in your Gantt Chart so you can more easily see

how tasks are related to one another.

You may also notice that the Legend will also display the different types of constraints and the

corresponding colors on the chart.

Histogram Plot


32/162

Resource plots show how the resources in your model are utilized over time. The histogram resource

plot is most useful for visualizing the partial utilization of resources that can be split up, e.g. a work

crew consisting of multiple people each of whom can carry out a different task.

To create a histogram plot, select Histogram Plot from the Displays menu item in the main Aurora

window. The newly created plot will initially be empty; youll need to specify exactly which resources or

resource sets youd like to see displayed. The Histogram Plot Configuration dialogue box will appear to

allow you to add resources to the display.

Resources in the right-hand pane of this dialogue will be displayed in the histogram plot. To add a

resource, select it in the left-hand pane and click the Add button at the bottom of the pane. Note that

you can also add entire resource sets in the By Resource Set tab, or choose resources by the activities

that utilize them in the By Task tab.


33/162

When youve added all the resources youre interested in plotting, click OK in the dialogue to draw the

plot.

An example histogram plot showing one resource is displayed above. The X-axis represents time

(increasing from left to right), and each resource is assigned to its own row. Within a row, utilization

amount is represented on the vertical axis, with the top of the row indicating the maximum amount of

the resource. The background color indicates the availability of the resource: a white background

indicates that the resource (or some amount of the resource, depending on the span of the color) is

available, while a blue background indicates that it is unavailable. Black boxes represent activities

utilizing a resource, with the width of the box indicating the span of usage time and height representing

the amount of the resource in use.

Clicking on boxes in the histogram display will show the activities that utilize the resource during the

periods spanned by the box. Double clicking on an activity will bring up a dialogue displaying its

properties.


34/162

Tabular Editor

The Tabular Editor is a powerful tool that gives you an easy way to view and edit a large number of

properties at once. It functions similarly to a spreadsheet and is an editable table of activities and

properties. To open the Tabular Editor, go to the Displays menu and select Tabular Editor from theoptions.

As shown in the above screen screenshot, each row will contain all the properties of the specified Activity.

The columns can be sorted by click on the heading of the column. A small arrow will display next to the

heading indicating that the table has been sorted according to that heading.

Each column can be resized by floating the mouse cursor over the line between the headers until a

double-sided arrow appears, clicking, and dragging to the desired size.


35/162

By cutting and pasting properties between cells, you can quickly and easily change a large amount of

data at once. Since Aurora does not provide drop-down boxes and some of the fields require exactly the

right text in order to work correctly, it is sometimes desirable to open the Activity properties window and

enter data there. You can do this by clicking on the button. This will open a dialogue box with theActivity properties. Then you can go back to the Tabular Editor, copy the data, and then paste it in the

appropriate column for as many other Activities as you wish.

Short Flash Video

Open the Gantt Chart display in Aurora by clicking on the Displays menu ->

Gantt Chart as shown below.

This is the default view that Aurora will show you.
http://www.stottlerhenke.com/products/aurora/tutorial/Videos/Gantt%20Constraints.swf.htmlhttp://www.stottlerhenke.com/products/aurora/tutorial/Videos/Gantt%20Constraints.swf.htmlhttp://www.stottlerhenke.com/products/aurora/tutorial/Videos/Gantt%20Constraints.swf.html


37/162

To show the constraints between tasks, click on the Configure howConstraints

are Displayed button.

This will bring up the Constraint Display Configuration dialogue box.

You can use this dialogue box to show the relationships between tasks on the

Gantt Chart. For now, we will select the Show all constraints radio button at the

top and click OK.


38/162

You will now notice that Aurora has added arrows to the Gantt Chart that show

the relationships between the tasks.

To help decode what the colored arrowed mean, you can have Aurora show the

Legendby clicking on the Display Legendbutton .


39/162

The Legend helps you understand that red arrows denote a Temporal Finish-

Startrelationship and that teal indicates a Start Driver relationship, which

indicates a resource-constraint.

Now you know what the different arrows mean, but its still difficult to see

where they are with the current display. To help with this issue, the next section

of this tutorial will now show you how to edit the way the Gantt Chart displaysto make information easier to see.

Customizing the Display


40/162

In Aurora, by customizing the Gantt Chart view, you can more easily see the

information that you need.

In the toolbar directly above the Gantt Chart, these two buttons will help you

customize the way the chart appears:

Configure Label Placement and Content

Change the placement and content of labels as displayed on the Chart

Configure Gantt

Configure how the Chart area looks


As you can see in the screenshot below, the default in Aurora is to display the Start Hourand End Hour

on either side of the bar that represents each Activity and the Primary Key Fn centered above the bar.

Note that the Primary Key Fn typically denotes the IP Numberof the Activity. The IP Numberis also what

is displayed on the PERT Chart in the Edittab.


41/162

These three fields can be customized by clicking on the button and changing the fields in the Label

Configuration dialogue box.


42/162

As you can see in the screenshot, the Label Configuration dialogue box provides

you with a visual way to edit the labels and placement. The default blue-

highlighted boxes (labels) can be moved by clicking and dragging with the

mouse and also resized by clicking and dragging the corners (note that the

cursor will not change when you hover over the corner). The labels will snap to

the grid and can be rearranged anywhere inside the dialogue. The Create, Edit,Remove, and Copy buttons allow you to create new labels and delete unwanted

labels as needed.

You can see the settings for each of the labels by clicking on them to highlight

them in the upper half of the dialogue box. The Settings section will change


43/162

with each label that is highlighted. You can change the function and alignment

of each label using the drop-down boxes.

Now lets do an exercise to change the Gantt Chart to clean up the display.

Exercise: Changing Labels

For this exercise, we will be changing the way the Gantt Chart displays by using

the Label Configuration dialogue.

To help clean up the display and make it more readable, lets start by getting rid

of the Start Hourlabel on the left. The way this schedule was created, the Start

Houris typically midnight and we can declutter the display by getting rid of that

label.

Start by highlighting the Start Hourlabel in the Label Configuration dialogue.

You will notice that the Settings section of the dialogue box will update to

display the information for the Start Hourlabel.


44/162

Now click on Remove button to delete this label. It will disappear from the

display. You will note that the Gantt Chart will update itself as you are making

changes in the dialogue box. If you decided to hit cancel, the Start Hourlabel

would reappear. The changes you make will not go into effect until you hit the

OKbutton at the bottom.

We will now change the End Hourto read the total number of hours per

Activity. Click on the End Hourlabel and choose Hour Duration from the

Functions drop-down menu.


45/162

If you would also like to change the display font, you can click on the button

and select a different font. We will not be changing the font in this exercise, but

if you so desire you may.

If you hit OK in the Label Configuration dialogue box, you will see that the Gantt

Chart view updates according to the edits you have made.


46/162

Configure Gantt

Now that we know how to change the labels and their placements, lets see what

else we can do with the Gantt Chart display using the Configure Gantt button

which looks like this: .

Clicking on this button will bring up the Gantt Plot Configurationdialogue.


47/162

We will only cover the Plot Definition tab in this tutorial.

Plot DefinitionThis tab shows you all the settings for the Gantt Chart Plot Area.


48/162

You can set how your Gantt Chart displays, including selecting the specific

colors for each item in the display. For now, we will just remove the vertical lines

from the Gantt Chart display. This will make it a bit easier to see the arrows that

show the constraints between Activities.

Uncheck the Vertical Linesbox and click OKat the bottom of this dialogue.

You will notice that now the Gantt Chart display is now much cleaner looking.


49/162

Still having trouble seeing how Activities relate to one another? You can try the

Single Element Display to see a single Activity and its predecessors and

successors.

Single Element Display

The Single Element Display will display any single, selected Activity and

show its predecessors and successors.

Click on any Activity in the Gantt Chart view to highlight it. A highlighted Activity will have a bold dashed

line outlining it.


50/162

When you have highlighted the desired Activity, click on the Single Element Display button . It will

bring up a display similar to that shown below.

As you can see, it is showing the workflow around Activity 6. The red arrows denote work flow and teal

arrows denote resource-constrained work flow.

Exercise: Single Element Display

Taking a look at your schedule in Auroras Gantt Chart view, you wonder why the re is a two day lagbetween when Activity 2 ends and Activity 6 begins.


51/162

If you look at the PERT Chart, you will also see that Activity 2 is the only predecessor to Activity 6.

According to this workflow, Activity 6 should start right after Activity 2 ends.

So why is there a 2 day gap between when Activity 2 ends and Activity 6 begins? To figure this out, youcan look at the Single Element Display.

By looking at the Single Element Display for Activity 6, you can tell that predecessors 2 and 5 must

happen before 6, but now you know that 5 is a resource-constraining Activity (denoted by the teal arrow)

so Activity 6 cannot start until Activity 5 has released enough resources. Similarly, you can also see that

although Activity 7 is the workflow successor to Activity 6, both Activities 3 and 8 depend on the

resources used by Activity 6; Activities 3 and 8 must wait for 6 to finish before they can start.

Preparing Files for Import by the Aurora Translator


52/162

The following short tutorial will help you correctly prepare your files for import into Aurora. While

Aurora itself is a fully-capable scheduling program, the Aurora Translator can sometimes

encounter difficulties when it comes to converting from other formats, e.g., MS Project. Here is

how to correctly format your file so that the conversion will be seamless.

Formatting MS Project files:

1. Open or create file in MS Project 2003 or 2007

These versions of MS Project will give you the most compatibility with the Aurora

Translator.

2. Verify that all activities or tasks within a project are linked together

a. All tasks must have a predecessor (with the exception of the first task)b. All tasks must have a successor (with the exception of the last task)

All activities or tasks must be linked to one another and originate from an initial task,usually the Start Project task. Similarly, the tasks should all have another task followingit, with the exception of the final task.

If you are using a multi-project network, then you must verify that each of the tasks ineach project has a predecessor and successor (with the exception of the initial and finalproject tasks).

This can be easily verified in the Gantt Chart view by selecting the Predecessors columnheader, right-clicking then selecting the Insert Columns option, then selectingSuccessors.

3. Verify that all the tasks with 0 duration (also called milestone tasks), do NOT have aresource associated with them.

This can be expedited by clicking on the menu bar, Project -> Sort -> Sort By andselection Duration in the dialogue box.

To return to the default Task Name sorting later, click on the menu bar, Project -> Sort ->by ID.

Aurora XML Import / ExportExample with Primavera P6

The original file, titled

Warehouse Project exported from P6 as MSP 2007 XML

Was created in Primavera P6, then exported into Microsoft project XML, via Primavera P6.

Then the file is imported as an Aurora using the built in Import capability, accessed via File->Import from

MS Project XML:


54/162

Before the import is completed, Aurora provides the following options:

Add common start & end task;

Aggressive durations set to _____% of current duration;

Round-trip planned.Explanation on the options:

Check the box to Add common start & end task. This exists because Aurora requires one

common start and one common end node. If the model being imported already containssuch, then do not select this option.

The _____ option allows the aggressive durations to be calculated as a percentage of the

safe durations.

The Roundtrip option retains the hierarchical structure of the original file when the file is

exported out of AuroraFor this example, the following selections are used:

After this import, Aurora hides the Summary Tasks. In the Duration Info tab for tasks, the Aggressive

Duration is 67% the original Safe Duration.


55/162

Clicking on CCPM on the task bar on the top of the screen brings up the following screen. Click on More

options to show the Buffer Length calculation options. For this example the 50% sum of aggressive

durations option is used.

Clicking 3. Insert Buffers will schedule the project. Below is the result of what the example project looks

like after it has been scheduled in Aurora:

57/162

Export the file back into Microsoft

In Aurora, go to File->Export to MS Project XML to save the current project as a XML to be read by

Primavera P6 (or Microsoft Project).

For this example, the results are shown in Microsoft Project. In MS Project, Go to the Open option

under File.

And select file format as XML:


58/162

Open the newly saved file XML file, import as New Project.

How to sort by start date in MS Project:

Aurora XML Import / Export & Translator tutorialThis document explains how to export a Microsoft Project file into Aurora, the different import

options available in Aurora, and the process to export a file out of Aurora and re-import into

Microsoft Project.

Note that the Microsoft Project XML format is a defacto industry standard that many other Project

Management packages support, for example

Primavera P6 &

Deltek Open Plan.

So the information here can be used when utilizing any software that supports Microsoft Project XML.

For example, if using Primavera P6, one can use the export to Microsoft Project XML option to

transfer information to Aurora, then use the import from Microsoft Project XML option to transfer

information to Aurora.

To export a file from Microsoft Office Project to be edited in Aurora, you must

export the file as a MS Project XML.

In Microsoft Project, go to File -> Save As


62/162

Then select Save as type: XML Format

This will save the file into a format readable by Auroras built in Import function.

To import a XML file saved from MS Project into Aurora:

Open up Aurora, then go to File->Import from MS Project XML:


63/162

Locate the XML file you saved earlier via Microsoft Project, then click Open.





64/162

Round-trip planned.

Explanation on the options:

Add common start & end task. This option exists because Aurora requires one common

start and one common end node. If the model being imported already contains such, then

do not select this option.

The Aggressive duration set to ____% of current duration option allows the aggressive

durations to be calculated as a percentage of the safe durations.

The Round-trip planned option retains the hierarchical structure of the original file whenthe file is exported out of Aurora

Export an Aurora file back into Microsoft Project

In Aurora, go to File->Export to MS Project XML to save the current project as a XML to be read by

Microsoft Project.

Then in Microsoft Project, go to the Open option under File.


65/162

And select file format as XML:

Find and open the newly saved file XML file, then import as New Project. This will reopen the file in MSproject and contains all the modifications made in Aurora.


66/162

*How to sort by start date in MS Project:


67/162

Below are examples demonstrating the import and exportcapability in conjunction with different analysis in Aurora:

Import with regular scheduling

Import with Critical Chain scheduling

Import with Round-trip option and regular scheduling

Import with Round-trip option and Critical Chain scheduling

Importing into Aurora with regular scheduling

For this example, click OK on the Aurora Import Options menu without checking any of the options.

Once the XML file has been imported into Aurora, go to Schedule -> Schedule

Check both options Show Summary Report When Scheduled and Suppress Warnings, then hit OK.


68/162

This is what the example file looks like in Aurora, scheduled (without Critical Chain)

A view of the project Gantt chart


69/162


70/162

Importing into Aurora, then Critical Chain Scheduling

Again, do not check any options in the Import Options menu.

Once the file has been imported, you can perform a Critical Chain scheduling by going to CCPM ->

Critical Chain

In the Critical Chain Settings, select 50% sum of aggressive durations for Buffer Length Method, then hit

Insert Buffers under Calculations.

The resulting, CCPM schedule produces a project that looks like the screenshot below:

This screenshot displays the hierarchy structure of the project currently in Microsoft Project, before

exporting to Aurora:

Check the round-trip planned box in Aurora Import Options

Below is what the project looks like in Aurora, notice the summary tasks from Microsoft Project have

disappeared, thanks to the Round-trip option

Using a basic template to create a new Critical Chainschedule

Getting started with Aurora can be a little confusing at first. This tutorial will show you how to use

a basic template to create a simple schedule. Once you learn how to create a simple schedule,you will have the basic understanding to create as complicated a schedule as you require.

The basic steps are as follows:

o Downloadthe template with one pre-loaded Activityo Copy the sample Activityto create as many Activities are you requireo Add constraintsto establish the relationships (predecessor and successor) between

Activities

o Add Resource Requirementsto your Activitieso Schedule your networkusing Aurorao Perform Critical Chain Analysison a schedule

Lets get started. Download theBasic Template (Basic Template.cmp)file by right-clicking on the link

and selecting Save Link As and load it into Aurora (File menu -> Open). Ensure that the

extension on this file is .cmp when saving.

When you open this file, you will notice that there is a new project called Basic Template with

one Activity under it.

81/162

What we will be doing in this tutorial is creating new activities and establishing constraints on

them to create a simple schedule. We will use the first Activity (labeled with a 1 in the screen

shot above) and will copy it to create a sample network. We will create all the Activities that we

need first (9 total) and then we will build the relationships between them. Activity 1 will be the

starting node and Activity 9 will be the ending node. Neither of them will have any time duration,

as they are simply the nodes where the projects begin and end. Only the Activities between them

will have time durations.

Click on the Activity to highlight it and press the copy button at the bottom of the left-hand pane.


82/162

After you press the Copy button, Aurora will create a new Activity that is identical to the original

and the screen should look like this when you click and highlight the new Activity.


83/162

You can now change the name and IP Number to be T1 and 2 as shown below:


84/162

Go to the Schedule Attributes tab in the middle pane and change the Active Duration to 1440

minutes.


85/162

Then, go to the Duration Info tab, and change the value for Safe Duration to 1440 minutes, and

the Aggressive Duration to 720 minutes. For critical chain, the rule of thumb is that the

Aggressive Duration will be half of the Safe Duration.


86/162

You may now continue in this manner to create more Activities. For this exercise, you will need to

create a total of 9 Activities with the following durations:

Activity # Name IP NumberActive and Safe

DurationsAggressive Duration

1 T0 1 0 0

2 T1 2 1440 720

3 T2 3 2880 1440

4 T3 4 5760 2880

5 T4 5 4320 2160

6 T5 6 1440 720

7 T6 7 7200 3600

8 T7 8 4320 2160

9 T8 9 0 0


87/162

The first two columns (Name and IP Number) will be entered in the Properties tab in the middle

pane. The durations will be entered in the Schedule Attributes tab in the middle pane.

Once you have created all the Activities, your window should look like this:

Add Constraints to your schedule

Now we are ready to add some constraints (predecessors and successors) and make this look

more like a schedule than a set of tasks.


88/162

Constraints are added by clicking on the Activity in either the left- or right-hand pane and then

clicking on the Constraints tab in the middle pane. Lets start with Activity 1. We would like

Activity 1 to be the predecessor to Activities 2, 3, 4, and 5. The easiest way to set constraints is to

click on the Predecessor and then add in the Successors using the Constraints dialogue.

Click on Activity 1 in the left-hand pane and then click on the Constraints tab in the middle pane.

Again, highlight the activity in the middle pane and click the Add button to open the Constraints

Wizard dialogue.

You will notice that Activity 1 is not selectable and is marked in red; this is because you cannot

add a constraint that loops back onto itself. What you want to do is select Activity 2 and then click

the Next button.


89/162

This will bring us to the second page of the Constraint Wizard, that will ask you to define the

relationship between the two constraints you have chosen (Activity 1 and Activity 2).


90/162

The first property in this new display (below the constraint type combo box) allows you to select

the temporal constraint type. The default Normal selection indicates that this temporal constraint

relates the start or end time of the first activity to the start or end time of the second activity.

Selecting Normal in the temporal constraint type combo box enables the activity relationship

property combo box directly below it, by default set to Finish


91/162

Since we are editing Activity 1 and would like to make Activity 2 the successor, we would like to

make this section read as Finish


92/162

Select Activity 6 in the next screen, and hit Next.


93/162


94/162

You will want to continue in this way to create constraints for every activity following the layout of

this diagram:

When you are done, your PERT display may look crowded and you may want to rearrange the

display by pressing (auto-arrange) in the bar above the right-hand side panel. You can then

press (auto-fit) to fit the elements to the display size.

You should get something similar to this view when you are finished:


95/162

Adding Resources to your ScheduleThis video illustrates the steps below, may be helpful to watch the video first, then follow the

steps.Video (Flash)

Note: In the example Basic Template.cmp file you downloaded for this tutorial, the resources

have already been defined. The following is for future projects that you may create.

Click on the Resources tab in the main edit area. Then click the New Resource button on the

bottom of the screen.

Click on the resource that has just been added, and adjust its properties via the

Properties/Constraints/Capacity tab. Here you can change things such as Name, Description,

Resource Type, Quantity, and other options for this newly created resource.

Adding Resource Requirements to Your Schedule

In the sample schedule that you have created so far, you have created Activities and established

the relationships between them. Now, you can go back to the individual Activities and add

Resource Requirements.

In the left-hand panel, click on Activity 2. In the middle panel, click on the Requirements tab.

Once youre there, click on the Add button to open the dialogue box. For this sample schedule,

we are going to use the A set of Requirements for all the Activities that require resources

(Activities 2 through 8).


98/162

Once you hit ok from this dialogue box, you will have added a resource requirement. You will now

see an added line in the Requirements tab that should look similar to below:


99/162

Depending on the Activity, you may need to change the quantity required. In this case, however,

for Activity 2, we can leave the quantity at 1 and continue. You will need to add resource

requirements to Activities 2 through 9 according to the following table:

Activity # Resource Set Quantity Required

2 A set 1

3 A set 2

4 A set 2

5 A set 2

6 A set 2

7 A set 1

8 A set 2

The reason why we do not add Required Resources to Activities 1 and 9 is because they functionas milestoneendpoints for our schedule. You will also notice that both Activity 1 and 9 have a

duration of 0 minutes. This is also due to the fact that they are milestones and are merely a

starting and ending point for the schedule.


100/162


101/162

Access the Schedule function by again going to the file menu: Schedule -> Schedule


102/162

This will bring up another dialogue box. You want to select Safe and check the box for Show

Summary Report when Scheduled and hit OK.

Aurora will now schedule the project and provide a Scheduling Summary Report window and a

Pre-Schedule Analysis Problem Report window. If you have made the network as described

above in the tutorial, you should see a Summary Report similar to this:


103/162

You can now close the Scheduling Summary Report window and the Pre-Schedule Analysis

Problem Report windows.

To see the schedule in Gantt Chart form, you can go to the Display menu and select Display ->

Gantt Chart.


104/162

Perform Critical Chain analysis on a schedule

Now, we will go through using Critical Chain in Aurora.

The following video illustrates the steps that will be performed below, it may be helpful to watchthe video first, then follow the steps.Video

Open the dialogue from CCPM -> Critical Chain
http://www.stottlerhenke.com/products/aurora/videos/2009-02-04_Example_from_Literature_Critical_Chain_4of4.swfhttp://www.stottlerhenke.com/products/aurora/videos/2009-02-04_Example_from_Literature_Critical_Chain_4of4.swfhttp://www.stottlerhenke.com/products/aurora/videos/2009-02-04_Example_from_Literature_Critical_Chain_4of4.swfhttp://www.stottlerhenke.com/products/aurora/videos/2009-02-04_Example_from_Literature_Critical_Chain_4of4.swf


105/162

Select More options under the Buffer Length Method to see additional options.


106/162

Under Critical Chain Selection the button for Random should already be checked. When

performing Critical Chain, there is sometimes more than one candidate. This would be a more

advanced concept and will not be covered during this tutorial. You should leave the selection at

Random.

In Buffer Length Method, since there is only one set of durations, the best option is the top one

of 50% sum of aggressive durations. Note that the percent can be changed to any number that

you would like using the number entry box to the left, but for this example. We will leave it at 50%.

Under Calculations you may choose to do all three steps individually by clicking on the three

buttons in succession, but you can also click Insert Buffers and all three steps (Find Critical

Chain, Find Chain Feeders, and Insert Buffers) will be performed automatically. After you click

Insert Buffers another dialogue window should pop up. Once Aurora is done calculating (it

should take only a few seconds) you can close all the dialogue windows and take a look at the

updated schedule.

You should now note that the Total Wall Clock Working Duration has changed. You may also

note that Aurora has inserted a number of Feeding Chains and identified the number of Critical

Chain Elements.


107/162

The new Gantt chart should look similar to this screenshot:


108/162

Note that the feeding buffers show up in blue in the Gantt chart view. By going back to the Edit

tab, you will be able to see the feeder buffers and project buffers in the Network Diagram.

Gantt Chart

The Gantt chart (based on a design developed by Henry Gantt in 1910) plots activities in a schedule by

the temporal order in which theyll be carried out. The X-axis represents time (increasing from left to

right), and activities are drawn as rectangles with start points and lengths corresponding to their start

dates and completion times respectively. Activities that overlap in time (i.e. activities that occur

simultaneously for some or all of their duration) are stacked vertically, leading to a general trend (with

the default display settings) of activities being drawn from the charts upper-left towards its lower-right.

To access the Gantt Chart display in Aurora click on the Displays menu -> Gantt Chart as shown below.
http://www.stottlerhenke.com/products/aurora/tutorial/Displays.htm#_Gantt_Charthttp://www.stottlerhenke.com/products/aurora/tutorial/Displays.htm#_Gantt_Charthttp://www.stottlerhenke.com/products/aurora/tutorial/Displays.htm#_Histogram_Plothttp://www.stottlerhenke.com/products/aurora/tutorial/Displays.htm#_Histogram_Plothttp://www.stottlerhenke.com/products/aurora/tutorial/Displays.htm#_Tabular_Editorhttp://www.stottlerhenke.com/products/aurora/tutorial/Displays.htm#_Tabular_Editorhttp://www.stottlerhenke.com/products/aurora/tutorial/Displays.htm#_Tabular_Editorhttp://www.stottlerhenke.com/products/aurora/tutorial/Displays.htm#_Histogram_Plothttp://www.stottlerhenke.com/products/aurora/tutorial/Displays.htm#_Gantt_Chart


111/162

You will notice that Aurora will create different tabs across the top bar as you open more windows. Use

these tabs to switch between the different displays. The Edit tab is where you created the schedule

parameters and where you can edit them as needed.


112/162


113/162


114/162

Clicking Show all constraints will link the tasks together in your Gantt Chart so you can more easily see

how tasks are related to one another.

You may also notice that the Legend will also display the different types of constraints and the

corresponding colors on the chart.

Histogram Plot


115/162


116/162

When youve added all the resources youre interested in plotting, click OK in the dialogue to draw the

plot.

An example histogram plot showing one resource is displayed above. The X-axis represents time

(increasing from left to right), and each resource is assigned to its own row. Within a row, utilization

amount is represented on the vertical axis, with the top of the row indicating the maximum amount of

the resource. The background color indicates the availability of the resource: a white background

indicates that the resource (or some amount of the resource, depending on the span of the color) is

available, while a blue background indicates that it is unavailable. Black boxes represent activities

utilizing a resource, with the width of the box indicating the span of usage time and height representing

the amount of the resource in use.

Clicking on boxes in the histogram display will show the activities that utilize the resource during the

periods spanned by the box. Double clicking on an activity will bring up a dialogue displaying its

properties.


117/162


118/162

By cutting and pasting properties between cells, you can quickly and easily change a large amount of

data at once. Since Aurora does not provide drop-down boxes and some of the fields require exactly the

right text in order to work correctly, it is sometimes desirable to open the Activity properties window and

enter data there. You can do this by clicking on the button. This will open a dialogue box with theActivity properties. Then you can go back to the Tabular Editor, copy the data, and then paste it in the

appropriate column for as many other Activities as you wish.

Short Flash Video

Open the Gantt Chart display in Aurora by clicking on the Displays menu ->

Gantt Chart as shown below.

This is the default view that Aurora will show you.
http://www.stottlerhenke.com/products/aurora/tutorial/Videos/Gantt%20Constraints.swf.htmlhttp://www.stottlerhenke.com/products/aurora/tutorial/Videos/Gantt%20Constraints.swf.htmlhttp://www.stottlerhenke.com/products/aurora/tutorial/Videos/Gantt%20Constraints.swf.html


120/162

To show the constraints between tasks, click on the Configure howConstraints

are Displayed button.

This will bring up the Constraint Display Configuration dialogue box.

You can use this dialogue box to show the relationships between tasks on the

Gantt Chart. For now, we will select the Show all constraints radio button at the

top and click OK.


121/162

You will now notice that Aurora has added arrows to the Gantt Chart that show

the relationships between the tasks.

To help decode what the colored arrowed mean, you can have Aurora show the

Legendby clicking on the Display Legendbutton .


122/162

The Legend helps you understand that red arrows denote a Temporal Finish-

Start relationship and that teal indicates a Start Driver relationship, which

indicates a resource-constraint.

Now you know what the different arrows mean, but its still difficult to see

where they are with the current display. To help with this issue, the next section

of this tutorial will now show you how to edit the way the Gantt Chart displaysto make information easier to see.

Customizing the Display


123/162

In Aurora, by customizing the Gantt Chart view, you can more easily see the

information that you need.

In the toolbar directly above the Gantt Chart, these two buttons will help you

customize the way the chart appears:


Change the placement and content of labels as displayed on the Chart

Configure Gantt

Configure how the Chart area looks


As you can see in the screenshot below, the default in Aurora is to display the Start Hourand End Hour

on either side of the bar that represents each Activity and the Primary Key Fn centered above the bar.

Note that the Primary Key Fn typically denotes the IP Numberof the Activity. The IP Numberis also what

is displayed on the PERT Chart in the Edittab.


124/162

These three fields can be customized by clicking on the button and changing the fields in the Label

Configuration dialogue box.


125/162

As you can see in the screenshot, the Label Configuration dialogue box provides

you with a visual way to edit the labels and placement. The default blue-

highlighted boxes (labels) can be moved by clicking and dragging with the

mouse and also resized by clicking and dragging the corners (note that the

cursor will not change when you hover over the corner). The labels will snap to

the grid and can be rearranged anywhere inside the dialogue. The Create, Edit,Remove, and Copy buttons allow you to create new labels and delete unwanted

labels as needed.

You can see the settings for each of the labels by clicking on them to highlight

them in the upper half of the dialogue box. The Settings section will change


126/162

with each label that is highlighted. You can change the function and alignment

of each label using the drop-down boxes.

Now lets do an exercise to change the Gantt Chart to clean up the display.

Exercise: Changing Labels

For this exercise, we will be changing the way the Gantt Chart displays by using

the Label Configuration dialogue.

To help clean up the display and make it more readable, lets start by getting rid

of the Start Hourlabel on the left. The way this schedule was created, the Start

Houris typically midnight and we can declutter the display by getting rid of that

label.

Start by highlighting the Start Hourlabel in the Label Configuration dialogue.

You will notice that the Settings section of the dialogue box will update to

display the information for the Start Hourlabel.


127/162


128/162

If you would also like to change the display font, you can click on the button

and select a different font. We will not be changing the font in this exercise, but

if you so desire you may.

If you hit OK in the Label Configuration dialogue box, you will see that the Gantt

Chart view updates according to the edits you have made.


129/162

Configure Gantt

Now that we know how to change the labels and their placements, lets see what

else we can do with the Gantt Chart display using the Configure Gantt button

which looks like this: .

Clicking on this button will bring up the Gantt Plot Configurationdialogue.


130/162

We will only cover the Plot Definition tab in this tutorial.

Plot DefinitionThis tab shows you all the settings for the Gantt Chart Plot Area.


131/162


132/162

Still having trouble seeing how Activities relate to one another? You can try the

Single Element Display to see a single Activity and its predecessors and

successors.

Single Element Display

The Single Element Display will display any single, selected Activity and

show its predecessors and successors.

Click on any Activity in the Gantt Chart view to highlight it. A highlighted Activity will have a bold dashed

line outlining it.


133/162

When you have highlighted the desired Activity, click on the Single Element Display button . It will

bring up a display similar to that shown below.

As you can see, it is showing the workflow around Activity 6. The red arrows denote work flow and teal

arrows denote resource-constrained work flow.

Exercise: Single Element Display

Taking a look at your schedule in Auroras Gantt Chart view, you wonder why the re is a two day lagbetween when Activity 2 ends and Activity 6 begins.

135/162

The following short tutorial will help you correctly prepare your files for import into Aurora. While

Aurora itself is a fully-capable scheduling program, the Aurora Translator can sometimes

encounter difficulties when it comes to converting from other formats, e.g., MS Project. Here is

how to correctly format your file so that the conversion will be seamless.

Formatting MS Project files:

1. Open or create file in MS Project 2003 or 2007

These versions of MS Project will give you the most compatibility with the Aurora

Translator.

2. Verify that all activities or tasks within a project are linked together

a. All tasks must have a predecessor (with the exception of the first task)b. All tasks must have a successor (with the exception of the last task)

All activities or tasks must be linked to one another and originate from an initial task,usually the Start Project task. Similarly, the tasks should all have another task followingit, with the exception of the final task.

If you are using a multi-project network, then you must verify that each of the tasks ineach project has a predecessor and successor (with the exception of the initial and finalproject tasks).

This can be easily verified in the Gantt Chart view by selecting the Predecessors columnheader, right-clicking then selecting the Insert Columns option, then selectingSuccessors.

3. Verify that all the tasks with 0 duration (also called milestone tasks), do NOT have aresource associated with them.

This can be expedited by clicking on the menu bar, Project -> Sort -> Sort By andselection Duration in the dialogue box.

To return to the default Task Name sorting later, click on the menu bar, Project -> Sort ->by ID.

Round-trip planned.Explanation on the options:

Check the box to Add common start & end task. This exists because Aurora requires one

common start and one common end node. If the model being imported already containssuch, then do not select this option.

The _____ option allows the aggressive durations to be calculated as a percentage of the

safe durations.

The Roundtrip option retains the hierarchical structure of the original file when the file is

exported out of AuroraFor this example, the following selections are used:

After this import, Aurora hides the Summary Tasks. In the Duration Info tab for tasks, the Aggressive

Duration is 67% the original Safe Duration.
