In a supply chain context, there are 7 potential locations of warehouses (denoted by i=1 to 7) from which the material has to be supplied to 3 supermarkets (denoted by =1 to. 3). You know the demand (Dj) of each supermarket and the supply capacity (Si) of each warehouse. There are fixed costs (Fi) of establishing the warehouse, and distribution costs per unit from any warehouse to any supermarket (C.) are known. You need to decide how many warehouses to establish and the distribution plan from each warehouse to each supermarket. Show the model formulation for the same by taking suitable assumptions.
