Q: The following is the current mathematical model for the production of Standard and Deluxe Bags by Par Manufacturing.
Max 10s + 9d
s.t.
7/10s +1d is < or equal to 630
1/2s + 5/6 d < or equal to 600
1s + 2/3 d < or equal to 708
1/10s + 1/4d < or equal to 135
S, D, > or equal to 0
Now, suppose that management encounters the following situations.
1) The accounting dept revises its estimate of the profit contribution for the deluxe bag to $18 per bag
2) The profit contribution per standard bag can be increased to $20 per bag(Assume the profit contribution for the deluxe bag is the original $9 value)
3) The sewing operation capacity has increased to 750 Hours (Assume that 10s + 9d is the appropriate objective function) If each of these situations is encountered separately, what is the optimal solution and the total profit contribution.
