The hawkins supply company is currently faced with an inventory rotation problem.this difficulty stems from the fact that some supplies must be used prior to a stated expiration date. upon receipt ,a new shipment of these perishable items must be stacked beneath the boxes that are currently in inventory. a substantial amount of time is consumed in restacking the items according to their expiration dates. The company would like to reduce the double and sometimes triple handling of items. How can this goal be achieved? are there alternative solutions which might also be effective?
