What is the difference between pure and mixed Integer Programming (IP) problems? Which do you think is most common, and why?

What is meant by satisficing, and why is the term often used in conjunction with Goal Programming?

What are deviation variables? How do they differ from decision variables in traditional LP problems?

If you were the president of the college and were employing GP to assist in decision- making, what might your goals be? What kinds of constraints would you include in your model?

What does it mean to rank goals in GP? How does this affect the problem’s solution?

Provide your own examples of problems where the objective is nonlinear and one or more constraints are nonlinear.

What are some of the questions that can be answered with project management?

What are the major differences between PERT and CPM?

What is an activity? What is an immediate predecessor?
