Network Design in Supply Chain and using a solver in Excel

I’m working on a Business exercise and need support.

• Assume that the company now faces the increased demand below (instead of the demand described in the original problem)

– New demand at each market region

• East : 300,000

• South : 1,000,000

• Midwest: 300,000

• West : 200,000

• Production costs, transport costs, and fixed costs of plants are same as those in Table 5-6

• Questions

– (1-1) Where should DryIce build its plants and how large should they be?

– (1-2) How much units should DryIce transport to each market region from each plant?

– Submit Excel files/sheet with all necessary conditions for Solver to run optimization – so that Solver models can be checked
