A company has four warehouses designed to hold inventory regionally (Denver, Cleveland, Atlanta and Pittsburgh). Three factories (Detroit, Boise, Dallas) produce two products to be stored in the warehouses. Demand for each product at each warehouse must be met in order to satisfy the demand of that region. Additionally, factories have limited capacity for total production of the two products (although there is no further constraint on how much of each product can be produced at a factory). Both of these are shown in the spreadsheet. Finally, the cost to ship product from each factory to each warehouse is given as well. The shipping cost is the same regardless of which product is being shipped. Build a linear optimization model to determine how many units of each of the two products should be shipped from each factory to each warehouse using a linear model
