Suppose the storage area for a warehouse is shown below. Two input docks (activity 40% from D1 and 60% from D2 respectively) and one output dock serve the storage area. All movements is in fill-pallet quantities. The storage area is divided in 1010ft storage bays. Five classes of products are to be stored. Class A needs moves at a rate of 100 Pallets/week and requires 5 storage bays. Class B needs moves at a rate of 60 Pallets/week and requires 4 storage bays. Class C needs moves at a rate of 50 Pallets/week and requires 5 storage bays. Class D needs moves at a rate of 30 Pallets/week and requires 2 storage bays. Class E needs moves at a rate of 20 Pallets/week and requires 2 storage bays. Indicate the optimal warehouse layout, show all supporting calculations
