ObjectivesObjectives
Know the steps for comparing Know the steps for comparing alternativesalternatives
Know how to determine the possible Know how to determine the possible set of alternatives set of alternatives
Know how to develop cash flows Know how to develop cash flows using the same planning horizonusing the same planning horizon
Steps for Comparing AlternativesSteps for Comparing Alternatives
1.1. Determine the feasible alternativesDetermine the feasible alternatives
2.2. Define the planning horizonDefine the planning horizon
3.3. Develop the cash flow profilesDevelop the cash flow profiles
4.4. Specify the MARRSpecify the MARR
5.5. Compare the alternativesCompare the alternatives
6.6. Perform supplementary analysesPerform supplementary analyses
7.7. Select the preferred alternativeSelect the preferred alternative
Determine Feasible AlternativesDetermine Feasible Alternatives
Alternatives can consist of various Alternatives can consist of various investment proposalsinvestment proposals
Proposals can be:Proposals can be: Mutually exclusiveMutually exclusive IndependentIndependent Contingent upon another proposalContingent upon another proposal
Mutual ExclusiveMutual Exclusive
At most one project out of the group At most one project out of the group can be chosen:can be chosen:
If I have proposals A, B, and C------- If I have proposals A, B, and C------- only A or B or C can be chosen (not a only A or B or C can be chosen (not a combination)combination)
IndependentIndependent
All, none or any combination may be All, none or any combination may be selectedselected
Total number of alternatives = 2Total number of alternatives = 2mm where m is the number of proposalswhere m is the number of proposals
If there are 4 proposals, the total If there are 4 proposals, the total number of options is 2number of options is 244 = 16 = 16 alternativesalternatives
ContingentContingent
The choice of a project is conditional The choice of a project is conditional on the choice of another projecton the choice of another project
If A is contingent on B then A can’t be If A is contingent on B then A can’t be implemented unless B is also implemented unless B is also implementedimplemented

Problems in standardizing the PHProblems in standardizing the PH
LCM-usually assume cash flow LCM-usually assume cash flow patterns repeatpatterns repeat
Shortest Life-Must estimate the Shortest Life-Must estimate the unused portions of the alternatives unused portions of the alternatives (salvage value)(salvage value)
Longest Life-Must estimate cash flow Longest Life-Must estimate cash flow patterns between the shortest and patterns between the shortest and longest lifelongest life
