Capacities of a large supply chain with 4 layers and 10 nods

We consider a case study of general supply chain with  four layers and  ten nodes at each layer , including suppliers, manufacturing plants, warehouses and customers. Indeed, such a model represents a complex network in which products are shipped from suppliers to plants where they are processed then redirected to warehouses, and finally directed to the customers. The shared data is regarding:

- sites capacities,

-customers yearly demands,

-costs of purchasing and shipping products to manufacturing sites,

-costs of shipping products from manufacturing sites to warehouses,

-costs of shipping products from warehouse to markets
