Do not include anything other than numbers in your responses. For example, do not include comma or dollar sign in your numbers. As a rule of thumb, keep 2 decimal places for larger numbers and 3 decimal places for smaller numbers less than 1. The manager of a car wash received a revised price list from the vendor who supplies soap, and a promise of a shorter lead time for deliveries. Formerly the lead time was 8 days, but now the vendor promises a reduction of 25 percent in that time. Annual usage of soap is 4620 gallons. The car wash is open 360 days a year. Assume that daily usage is normal, and that it has a standard deviation of 2 gallons per day. The ordering cost is $35 and annual carrying cost is $4 a gallon. The revised price list (cost per gallon) is shown in the following table: Order Size Unit Price 2 1--299 300--599 1.7 600++ 1.62 The store manager is considering to provide a service level of 0.55. How much is the Quantity from EOQ? (Keep two decimal places) How much is the total annual inventory related costs (holding, ordering, and purchase costs), if the car wash order the quantity from EOQ model? How much is the total annual inventory related costs (holding, ordering, and purchase costs), if the bakery orders just enough to get the soap at the price of $1.7? How much is the total annual inventory related costs (holding, ordering, and purchase costs), if the car wash orders just enough to get the soap at the price of $1.62? What is the car wash's optimal order quantity, given this quantity discount information? How often (in days) should the car wash order? How long (in days) is the lead time? What is the Z value for the desired service level? How much safety stock is needed to provide the desired service level? What is the ROP for the desired service level? Do not include anything other than numbers in your responses. For example, do not include comma or dollar sign in your numbers. As a rule of thumb, keep 2 decimal places for larger numbers and 3 decimal places for smaller numbers less than 1. A small copy center uses approximately 28 boxes of copy paper a week. Experience suggests that usage can be well approximated by a normal distribution with a standard deviation of 10 box per week. 4 weeks are required to fill an order for letterhead stationery. Ordering cost is $4, and annual holding cost is $0.44 per box. The manager's desired service level is 0.8. Assume a year is 52 weeks. How much is the annual demand rate? How much is the optimal order quantity? (keep two decimal places) How many times a year the copy center place a new order of papers? (keep two decimal places) How many weeks does each order of paper last? Compute the total annual cost of ordering and carrying boxes of papers: What is the Z value for the desired service level? How much safety stock is needed to provide the desired service level? What is the ROP for the desired service level? Do not include anything other than numbers in your responses. For example, do not include comma or dollar sign in your numbers. As a rule of thumb, keep 2 decimal places for larger numbers and 3 decimal places for smaller numbers less than 1. Demand for walnut fudge ice cream at the Sweet Cream Dairy can be approximated by a normal distribution with a mean of 100 gallons per week and a standard deviation of 19 gallons per week. The new manager desires a service level of 65 percent. Lead time is 2 days, and the dairy is open seven days a week (Hint: work in terms of weeks). What is the Z value for the desired service level? How many (fraction of) "weeks" is the lead time? If we use a continuous inventory system, what safety stock level would be consistent with the desired service level? If we use a continuous inventory system, what ROP would be consistent with the desired service level? Do not include anything other than numbers in your responses.
