- Your firm uses a continuous review system and operates 52 weeks per year. One of the SKUs has the following characteristics.Demand 1D2 = 20,000 units/yearOrdering cost 1S2 = $40/orderHolding cost 1H2 = $2/unit/yearLead time 1L2 = 2 weeksCycle@service level = 95 percentDemand is normally distributed, with a standard deviation of weekly demand of 100 units.Current on-hand inventory is 1,040 units, with no scheduled receipts and no backorders.a. Calculate the item’s EOQ. What is the average time, in weeks, between orders?b.

Demand is reasonably constant throughout the year, and last year the company sold 2,000 tonnes of this product. It estimates the costs of placing an order at around £25 each time an order is placed, and calculates that the annual cost of holding inventory is 20 per cent of purchase cost.

- As inventory manager, you must decide on the order quantity for an item that has an annual demand of 2,000 units. Placing an order costs you $20 each time. Your annual holding cost, expressed as a percentage of average inventory value, is 20 percent.

Group of answer choices greater than $1800 but less than or equal to $2100Demand for a product is relatively constant at 5 units per day. Lead time for this product is normally distributed with a mean of 20 days and a standard deviation of 4 days. (a) What reorder point provides an 80 percent service level?
