GM manufactures bikini swimming suits. Their business is highly seasonal, with expected demands being 2800, 500, 100, and 850 dozen suits over the four quarters of next year. The company can produce 1200 dozen suits per quarter, but inventories must be built up to meet larger demands at a cost of $15 per dozen per quarter. GM wants to meet demand while minimizing this inventory cost. Formulate a time-phased LP with infinite time horizon. Find the optimum solution using any solver

Your firm uses a periodic review system for all SKUs classified, using ABC analysis, as B or C items. Further, it uses a continuous review system for all SKUs classified as A items. The demand for a specific SKU, currently classified as an A item, has been dropping. You have been asked to evaluate the impact of moving the item from continuous review to periodic review. Assume your firm operates 52 weeks per year; the item’s current characteristics are:Demand 1D2 = 15,080 units/yearOrdering cost 1S2 = $125.00/orderHolding cost 1H2 = $3.00/unit/yearLead time 1L2 = 5 weeksCycle@service level = 95 percentDemand is normally distributed, with a standard deviation of weekly demand of 64 units.a. Calculate the item’s EOQ.b. Use the EOQ to define the parameters of an appropriate continuous review and periodic review system for this item.c. Which system requires more safety stock and by how much?

A logistics company applies the EOQ model to manage its inventory of spare parts used for maintenance work for their trucks. Daily demand is normally distributed. The average daily demand is 10 units, with a standard deviation of 5 units. The EOQ is found to be 400 units and used as the order size for all orders. Order lead time is 4 days. Currently, the firm has just received an order. In how many days do they need to place the next order? 4 days 36 days 40 days None of the above. Demand is random, so the time until they reach the ROP again is also random
Zara's success relies on keeping a significant amount of its production in-house and making sure that its own factories reserve 85 percent of their capacity for in-season adjustments. In-house production allows the organization to be flexible in the amount, frequency, and variety of new products to be launched. Zara employ this inventory method which reduces inventory costs and requires them to forecast demand accurately.
Backorders: A company is working on its quarterly aggregate production plan. Its quarter forecasts are 6000, 1000, 2500 and 2000, respectively.

A manufacturer has a production facility that requires 15,604 units of component JY21 per year. Following a long-term contract, the manufacturer purchases component JY21 from a supplier with a lead time of 7 days. The unit purchase cost is $25.6 per unit. The cost to place and process an order from the supplier is $121 per order. The unit inventory carrying cost per year is 10.5 percent of the unit purchase cost. The manufacturer operates 250 days a year. Assume EOQ model is appropriate. If the manufacturer uses a constant order quantity of 2,640 units per order, what is the annual holding cost? Use at least 4 decimal places.
