Illustration (Example 10.21) We are to design a warehouse layout, given that Storage bays are of size 20ft X 20 ft each. Docks P1 and P2 are for truck delivery; docks P3 and P4 are for rail delivery. Dedicated storage is used. Sixty percent of all item movement in and out of storage is from/to either P1 or P2, with each dock equally likely to be used. Forty percent of all item movement in and out of storage is equally divided between docks P3 and P4. Three products, A, B, and C, are to be stored in the warehouse with only one type of product stored in a given storage bay. Product A requires 3,600 ft of storage space and enters and leaves storage at a rate of 750 loads per month; product B requires 6,400 ft of storage space and enters and leaves storage at a rate of 900 loads per month; product C requires 4,000 ft of storage space and enters and leaves storage at a rate of 800 loads per month. Rectilinear travel is used and is measured between the centroids of storage bays.
