- The chapter presented various approaches for the control of inventory investment. Discuss three additional approaches not included that might involve supply chain managers.arrow_forwardThe Big Buy Supermarket stocks Munchies Cereal. Demand for Munchies is 4,000 boxes peryear (365 days). It costs the store $60 per order of Munchies, and it costs $0.80 per box per yearto keep the cereal in stock. Once an order for Munchies is placed, it takes 4 days to receive theorder from a food distributor. Determine The reorder pointarrow_forwardAnnual demand for a product is 13,000 units; weekly demand is 250 units with a standard deviation of 40 units. The cost of placing an order is $100, and the time from ordering to receipt is four weeks. The annual inventory carrying cost is $0.65 per unit. To provide a 98 percent service probability, what must the reorder point be? Note: Use Excel's NORM.S.INV() function to find the z value. Round z value to 2 decimal places and final answer to the nearest whole number. Suppose the production manager is told to reduce the safety stock of this item by 100 units. If this is done, what will the new service probability be? Note: Use Excel's NORM.S.DIST() function to find the correct probability for your computed z value. Round z value to 2 decimal places and final answer to the nearest whole percent.arrow_forward
