In determining open-to-buy, what is subtracted from planned purchases? O On hand On order EOM stock BOM stock Question 37 Your department is planning a 10 percent increase in sales for the entire three- month period (February-April). Sales for the period last year were $19,000. Fifty percent of the total planned sales are projected to occur in March, and 25 percent of sales are planned to occur in each of the other two months. Planned stock-sales ratio for each month is 2.0. Total planned reductions for the period are 5 percent of planned sales. Reductions are projected to occur for each month as follows: February (10 percent), March (40 percent), and April (50 percent). An ending inventory of $5,000 is planned for the period. PLANNED PURCHASES FOR FEBRUARY ARE: O $24,200 O $15.779 O None (overbought). $10.895.50

Your company has previously used a fixed order size where ordering takes place once a quarter, but since the product's sustainability only allows warehousing for a limited time, demand varies somewhat and the product's character also means that the stock cost is rather expensive, SEK 54 per product and year. So, the company wants to investigate whether a more dynamic order size is preferable. Each order costs the company approximately SEK 1,200. The forecast for the next 4 months is given below: Month 1 2 3 4 Forecast 180 320 490 180 Decide in which periods ordering should take place (you can choose the calculation method).
Chris usually sells 120 copies of newspaper each day and believe that sale are normally distributed, with a standard deviation of 15 papers. He pays 70 cents for each paper, which sells $1.25. For each unsold paper, he receives 30-cent credit. a) determine how many papers he should order each day b) calculate the stockout risk for that quantity.
Consider a two-stage plant-retailer supply chain. Lead time for orders is two weeks. Safety stock is equal to one week's demand, and future demand is estimated by the average of the past two weeks. a) Develop production planning model (equations) for the retailer that states the order-up-to rule, and order quantities as a function of time. b) Using a table format (Columns are Week, Starting retail inventory, On order, Order-up-to target, Order quantity, and Demand) track performance of the retailer for eight weeks if demand suddenly shifts from 100 units per week to 110 units per week starting in period 3 and stays at 110 to the end.

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?
