Q1) A company has a contract with several retailer to satisfy the demand of a specific product. For this reason, the manager of the company decided to establish some plants in some candidate locations. The final product is made using raw materials that can be provided by a set of supplies. The following figure shows a schematic overview of the corresponding supply chain network.
