A food company produces tomato sauce at five different plants. The tomato sauce is then shipped to one of three warehouses, where it is stored until it is shipped to one of the company's four customers. All of the inputs for the problem are given in the file P14_92.xlsx, as follows: The plant capacities (in tons) The cost per ton of producing tomato sauce at each plant and shipping it to each warehouse The cost of shipping a ton of sauce from each warehouse to each customer The customer requirements (in tons) of sauce The fixed annual cost of operating each plant and warehouse. The company must decide which plants and warehouses to open, and which routes from plants to warehouses and from warehouses to customers to use. All customer demand must be met. A given customer's demand can be met from more than one warehouse, and a given plant can ship to more than one warehouse. Hint: This is a two-echelon problem! a- Write the optimization model. b- Determine the minimum-cost method for meeting customer demands using Excel Solver
