in future goodwill. It pays $60 for each chair and sells it for $100. The annual
holding a chair inventory is 30% of its purchase cost.
Furnitures estimates that each stockout causes a loss of $50
a) Assuming that all demand is backlogged, what are the reorder point and the
safety stock level?
b) To meet 99% service objective, what should be the safety stock level for
Type 1 Service? For Type 2 Service?
A firm orders on average 400 wheels each month. Demand is normally distributed with standard deviation of the monthly demand being 20 wheels. The ordering cost is $8 per order. The cost to buy one wheel is $4 per wheel. Annual carrying costs are 50% of unit cost. The supplier lead time is 2 operating days. The firm operates 240 days per year, in other word, the firm operates 20 days each month. Each order is received from the supplier in a single delivery. There are no quantity discounts.
1h. What is the standard deviation of demand during lead time period?
An item has normally distributed demand with a mean of 100 and a standard deviation of 50. They order a week with one week lead time. Backorders are allowed.
A) With an order-up-to level of 300, on-hand inventory of 200, and on-order inventory of 60, how much will be ordered this week?
B) What is the standard deviation of demand over 2 weeks?
