Q: In the Great Threads model, we found an upper bound on

In the Great Threads model, we found an upper bound on production of any clothing type by calculating the amount that could be produced if all of the resources were devoted to this clothing type. a. W...

Q: In the last sheet of the file Fixed Cost Manufacturing Finished.

In the last sheet of the file Fixed Cost Manufacturing Finished.xlsx, we illustrated one way to model the Great Threads problem with IF functions that didn’t work. Try a slightly different approach he...

Q: In the Dorian production model, suppose that the production quantity of

In the Dorian production model, suppose that the production quantity of compact cars must either be less than or equal to 100 (a small batch) or greater than or equal to 1000 (a large batch). The same...

Q: Suppose in the Dorian production model that no minimum production limits are

Suppose in the Dorian production model that no minimum production limits are placed on the individual vehicle types. However, minimum production limits are placed on all cars and on all minivans. Spec...

Q: In the original Western set-covering model, we used the

In the original Western set-covering model, we used the number of hubs as the objective to minimize. Suppose instead that there is a fixed cost of locating a hub in any city, where these fixed costs c...

Q: In the original Western set-covering model, we assumed that

In the original Western set-covering model, we assumed that each city must be covered by at least one hub. Suppose that for added flexibility in flight routing, Western requires that each city must be...

Q: Set-covering models such as the original Western model often have

Set-covering models such as the original Western model often have multiple optimal solutions. See how many alternative optimal solutions you can find. Of course, each must use three hubs because this...
