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
