As per Chegg guidelines i answer first 4 parts of 1 question
Alternative | Low | Moderate | High | Maximum |
Small | 53 | 31 | 22 | 53 |
medium | 29 | 42 | 32 | 42 |
Large | -5 | 30 | 53 | 53 |
(A):-
The best decision under uncertainty using MAXIMAX is to select Small or Large facility.
The maximax criteria gives maximum of the maximum gains found in each event.
(B):-
The best decision under uncertainty using MAXIMIN is to select Medium facility.
The minimax criteria gives minimum value among all the possible maximum gains found in each facility.
(C) :-
Alternative | Equal likelihood | |
Small | 53*0.33 + 31*0.33 +22*0.33 = 17.49+10.23 + 7.26 | 34.98 |
medium | 29*0.33 + 42*0.33 + 32*0.33 = 9.57 + 13.86 + 10.56 | 33.99 |
Large |
-5*0.33 + 30*0.33 + 53*0.33 = -1.65 + 9.9 + 17.49 |
25.74 |
The best decision under uncertainty using LAPLACE/EQUALITY LIKELY is to select Small facility
(D):-
Alternative | Expected value | |
Small | 53*0.35 + 31*0.30 + 22*0.35 = 18.55 + 9.3 + 7.7 | 35.55 |
medium | 29*0.35 + 42*0.30 + 32*0.35 = 10.15 + 12.6 + 11.2 | 33.95 |
Large | -5*0.35 + 30*0.30 + 53*0.35 = -1.75 + 9 + 18.55 | 25.8 |
Expected monetary value of Large facility is 25.8 . It could be seen from the table, large facility provides the expected monetary value which is equivalent to 25.8
(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 Small facility
here because small facility expect monetory value is High 35.55 see in table above.

This question refers to an example in the book Production/Operations Management by William J. Stevenson. The example involves a capacity-planning problem in which a company must choose to build a small, medium, or large production facility. The payoff obtained will depend on whether future demand is low, moderate, or high, and the payoffs are as given in the following table: Alternatives Small facility Medium facility Large facility Possible Future Demand Low Moderate High $11 $11 $11 8 13 13 -$5...
