Answers::

(A). The optimal values are represented by final values in the variable cells table given above. Therefore,

Optimal number of Essential model = 80

Optimal number of comfort model = 120

Optimal number of majestic model = 0

Given, objective function = 63E + 95C + 135M

Therefore,

Maximum Profit = 63×80 + 95×120 + 135×0

Maximum Profit = $ 16,440

(B). From the constraints table given in the question, it can be observed that for assembly time, the final value is less than constraint R.H. side value which demonstrates that it has some extra Capacity.

Amount of extra Capacity for assembly time = 2400 - 2080 = 320

(C). No, the optimal solution will not change.

The objective coefficient for Majestic model is 135 and its allowable increase is 24 which means the the optimal solution will not change even if the coefficient of majestic model is increased to (135+24) = 159 and for any value of coefficient of majestic model above 159, the optimal solution changes. Therefore, if objective coefficient of majestic model is increased to 150, the optimal solution won't change.

(D). The shadow price corresponding to fans is 31 which demonstrates that a unit change in the constraint R.H. side of fans will change the value of optimal solution by $ 31.

Therefore, if 20 fans are damaged, then constraint R.H. side decreases by 20. Therefore the profit will reduce by (20 × $31) = $ 620

(E). It can be seen that the reduced cost for majestic model is blank. It can be observed that unlike essential and comfort models, Majestic model has a final value of zero which means the reduced cost of Majestic model will not be zero and it will take the negative value of kts allowable increase. Therefore, reduced cost for majestic model will be -24.

(F) In this, we first calculate the percentage of each model by dividing the amount decreased or increased with its corresponding allowable decrease or increase.

Therefore,

Percentage for essential model = 100 × (6/12) = 50%

Percentage for comfort model = 100 × (2/8) = 25%

Percentage for majestic model = 100 × (4/24) = 16.67%

Therefore, total percentage = 50% + 25% + 16.67% = 91.67%

Since the total percentage is less than 100%, therefore the optimal solution will not change.

Therefore, new objective function becomes:

Z = 69E + 93C + 139M

New Maximum profit = 69×80 + 93×120 + 139×0

New Maximum profit = 16,680
