Consider the following warehouse with square storage grids numbered 1 through 20. All pallets enter through port 1 (SW corner, gird id#1 ). 40% of the pallets depart through port 2 (SE corner, grid#4) and 60% use port 3 (NW corner, grid#13). Two product types are stored. Product type 1 requires 4 grids and product type 2 requires 16. Total product throughput is 20 pallets per day for product type 1 and 40 pallets per day for product type 2. Each grid is 1 x 1. In which grids should you store product type 1? (Note: You must show your computations for at least one grid location).
