DISCUSSION 3

Many LP models can be viewed through the lens of a Transpotation model. Choose one of the following types of problem and explain how to see it as a Transpotation problem. That is, explain what the “goods” we are shipping are, what the “roads” we are shipping along are, what the costs of “shipping” are, what the supply” and “demand” are:

DISCUSSION 1

Give specific instances in which you would use an integer programming model rather than an LP model.  Provide real-world examples.

DISCUSSION 3

Do you think Integer Programming or Linear Programming has more real world applications? Why? If Integer Programming is more prevalent, why do we focus so much on Linear Programming in this course? If Linear Programming is more prevalent, what do you think the challenges are facing Linear Programmers (since software like QM can handle all the computations)?
