A two-stage supply chain problem with fixed costs - 2018/12

The two-stage supply chain problem with fixed costs consists of designing a minimum distribution cost configuration of the manufacturers, distribution centers and retailers in a distribution network, satisfying the capacity constraints of the manufacturers and distribution centers to meet the retailers’ specific demands. This set of instances is used in the computational experiments and were generated randomly and belong to three classes of problems: smaller which consists of 2 plants, 5 distribution centers and 10 retailers, medium which consists of 4 plants, 8 distribution centers and 15 retailers and larger which consists of 6 plants, 10 distribution centers and 20 retailers.
