a) The best decision under uncertainty using MAXIMAX is to select  facility
  
b) The best decision under uncertainty using MAXIMIN is to select  facility
  
c) The best decision under uncertainty using LAPLACE/EQUALITY LIKELY is to select  facility

d) If the probabilities for Future Demand when it is Low = 0.35, Moderate = 0.30, and High = 0.35, the expected monetary value (EMV) for the large facility = .

e) If the probabilities for Future Demand when it is Low = 0.35, Moderate = 0.30, and High = 0.35, the best decision under risk is to select facility.

Homework Answers

Answer #1

a)

Maximax - Find the maximum payoff for each alternative and select the alternative which gives the maximum of these maximums.

Alternatives Future Demand Max
Low Moderate High Payoff
Small Facility 33 22 18 33
Medium Facility 19 32 22 32
Large Facility -10 29 43 43

So,

Best decision = Large facility

b)

Maximin - Find the minimum payoff for each alternative and select the alternative which gives the maximum of these minimums.

Alternatives Future Demand Min
Low Moderate High Payoff
Small Facility 33 22 18 18
Medium Facility 19 32 22 19
Large Facility -10 29 43 -10

So,

Best decision = Small facility

c)

Laplace - Find the average payoff for each alternative and select the alternative which gives the maximum of these averages.

Alternatives Future Demand Average
Low Moderate High Payoff
Small Facility 33 22 18 24.33
Medium Facility 19 32 22 24.33
Large Facility -10 29 43 20.67

So,

Best decision = Small or Medium facility

d)

The EMV for large facility = 0.35*(-10) + 0.30*(29) + 0.35*(43) = 20.25

e)

The EMV for large facility = 0.35*(-10) + 0.30*(29) + 0.35*(43) = 20.25
The EMV for medium facility = 0.35*(19) + 0.30*(32) + 0.35*(22) = 23.95
The EMV for small facility = 0.35*(33) + 0.30*(22) + 0.35*(18) = 24.45

So,

Best decision = Small facility
