Supply chain network.

Below is a general supply chain network.

9(Word.doc, Excel)

Given the picture define an optimization modeling and solve it that includes
network modeling,

integer programming,

simulation and forecasting modeling.

1. Describe the problem.
2. Write all the required assumptions.
3. Report all the information and data you need for your problem.
4. Define the objective function(s) and decision variables.
5. Write all the required constraints (at least 10 constraints).
6. Solve the problem in excel.

· Your model may include network modeling, integer programming, nonlinear programing, simulation and forecasting modeling (At least 2 of them. The more is better!).

· You can generate data or use some real data. If you are generating data should makes sense (for example unit price is greater than unit cost).

· You don’t have to consider all the stages of the supply chain.
