SCOPE OF SYSTEM

ANALYSIS SYSTEM SCIENCE

SYSTEM DEVELOPMENT

SYSTEM MODELLING


3/21

Characteristic of System Science

presenting the system concept toconstruct the structural components

in form of the framework of system as

result of certain ideas

appropriate knowledge to applicate

the system framework


4/21

System Science

System analysis is a set of procedureswhich basically used to design and

manage complexity of real-world

systems.

These activities was combined to

reach the big objective.


5/21

The evolution of system

science Cybernetics (Norbert Wiener, 1948):

In its narrow view, Cybernetics is

equivalent to serve a theory in

engineering;in its broadly view, it may encompass

much of natural science. Cybernetics

has to do with self-regulation, such asmechanical, electromechanical,

electrical, or biological, social


6/21


science General system theory (Ludwig von

Bertanlanffy, 1940):

GST is concerned with developing

a systematic framework for describinggeneral relationships in the natural

and the man-made world


7/21


science Systemology: the science of systems

or their formation.

A system science is pushed

forward by the formations of inter-disciplines

WHAT IS A SYSTEM?

A system is an assemblage or combinationof elements or parts forming a complex orunitary whole; (river system)

A set of regulations that restrict to both thecapacity of the system itself or theenvironment to be in ( system in law)

A system is an ordered and comprehensive

assemblage of facts, principles or doctrinesin a particular field of knowledge or thought(system of philosophy)


9/21

WHAT IS A SYSTEM?

A system is a coordinated methods ora complex scheme or plan of

procedure (system of organization and

management)

A system is any regular of special

method or plan of procedure (a

system marking, numbering ormeasuring)


10/21

WHAT IS A SYSTEM?

System is an assembly of elements orcomponents or part related in an

whole to reach an objective within a

complex environment

Systems have characteristic or property

ascribed to an element or process is

termed an attribute of that element(color, texture, size, strength, shape,

and permeability) or process (intensity,

speed, rate)


11/21

Part of system definition are:

Elements or components or parts

Relationships or interaction among

elements/components/ parts

There are something that connectedto be unity

There are objectives

It is lied in a complex environment


12/21

Elements or Components areoperating parts of a system consisting

of input, process, and output.

Each system component may assume

a variety of values (attributes) to

describe a system state as set bycontrol action and one or more

restrictions.


13/21

Attributes are the properties or

discernible manifestations of the

component/elements of a system

Atributes should relevant to the system

goalsAttributes characterize the

paramenters of a system

Parameters is a unity of quantitydetermines system value and

condition


14/21

Relationships are the links between

components and attributes; lead to

sinergism


15/21

Interaction is used to delivered a

binding between system elements orcomponents to express one or some

certain behaviors

Goals or objectives is theperformance result of system behavior

Environment is used to diferentiate

one system and another


16/21

System conception Concept is a phenomenon abstraction that was

formulated by generalization of a number of

cases characteristics

Concept is built from established definition

Definition is a set of terminology such assentences, symbols or mathematical formula that

shows the phenomenon as in the intended

concept


17/21

System conception Systemic Conception is a presentation of the system

components that forming from and into a solid

definition

Systemic Conception is the initial of systemanalysis that will be designed and evaluated

Systemic conception will be used to answer several

question about system, such as :

a. What are element of system?

b. What is/are the goals?

c. What will be done to reach the goals?d. What kind of process that is held?

e. What kind of output that is resulted by process??

f. What is the criteria to determine the process

succesfullness??
