SCMD: Assignment
The company produces an apple product at three plants, which can be delivered directly to the two customers or it can first be shipped to the two warehouses and then to the customers. Shipments between plants are allowed. This also applies to between warehouses and between customers.
The cost of producing the apple product is the same at each plant; as a result, the company is only concerned with minimising the total shipping cost incurred in meeting customer demands. The production capacity of each plant (in tons per year) and the customer demand are summarised in the table below:
