Question 1:

Which of the following are potential pitfalls of using a non-zero suboptimality tolerance factor?

a) No assurance the returned solution is optimal.

b) No assurance the returned solution is integer.

c) There are no pitfalls to consider since the Solver will obtain solutions quicker.

Question 2:

A production company wants to ensure that if Product 1 is produced, production of Product 1 not exceed production of Product 2. Which of the following constraints enforce this condition?

a) Xsub1 greater than or equal to Msub2Ysub2

b) Xsub1 less than or equal to Msub2Xsub2

c) Xsub1 less than or equal to Xsub2

Explanation / Answer

Question 1)

The suboptimality tolerance factor is used to get an integral solution. Integral solutions may not be an optimal solution. Hence the answer is:

a) No assurance the returned solution is optimal.

Question 2)

The answer is:

c) X1 <= X2

This explains if X1=0, then it is obviously <= X2, since X2 is qty (a non-negative integer)

Also, if X1>0 (ie if Product 1 is produced, it is <= X2 (qty) of product 2)

I am 100% sure of this!
