Paul’s Toy Distributor (PTD) sells 200 game consoles every week. PTD charges a $300 fixed cost for every delivery. PTD’s annual inventory holding cost is $45 per console. Assume that there are 52 weeks a year.
Assume that PTD orders 1000 game consoles at a time.
What is the average amount of time the consoles stay as PTD’s inventory before being sold? Find the closest answer.
A restaurant has an annual demand for 886 bottles of California wine. It costs $2 to store 1 bottle for 1 year, and it costs $10 to place a reorder. Find the optimum number of bottles per order.
A car rental agency uses 96 boxes of staples a year. The boxes cost $5 each. It costs $10 to order staples, and it costs $0.80 to hold a box of staples in inventory for 1 year.
A.) How many boxes of staples should the car rental company order each time it needs staples, to minimize the combined ordering and holding costs for staples?
B.) Using the order size that minimizes the car rental agency’s combined ordering and holding costs for staples, how long will a single order of staples last the agency, before it must receive more staples? (Assume there are 52 weeks in the year for the car rental agency.)
C.) Using the order size that minimizes the car rental agency’s combined ordering and holding costs for staples, how much does the car rental agency actually spend on holding costs for staples each year?

The demand for bolts is fairly constant; on the average, the manager, Michelle Wu, has observed that the hardware store sells 500 of these bolts each day. Because the demand is fairly constant, Michelle believes that she can avoid stockouts completely if she orders the bolts at the correct time. What is the reorder point?

The cost of carrying the alcohol in inventory is P0.50 per gallon per year, and the cost of ordering is P150 per order. The firm uses the alcohol at a constant rate throughout the year. It takes 18 days to receive an order once it is placed.

An American distributor stops by every four weeks to take orders. Because the orders are shipped directly from Italy, they take three weeks to arrive. Little Caesars Pizza uses an average of 150 pounds of pepperoni each week, with a standard deviation of 30 pounds. Little Caesars prides itself on offering only the best quality ingredients and a high level of service, so it wants to ensure a 98 percent probability of not stocking out on pepperoni. Assume that the sales representative just walked in the door and there are currently 500 pounds of pepperoni in the walk-in cooler. How many pounds of pepperoni would you order? What is the standard deviation of demand during the review period and lead-time? How many pounds of pepperoni would you order?arrow_forward

The ketchup costs $3.00 per bottle and is served only in whole bottles because its taste quickly deteriorates. The restaurant figures that it costs $10.00 each time an order is placed, and holding costs are 20 percent of the purchase price. It takes 3 weeks for an order to arrive. The restaurant operates 50 weeks per year. The restaurant would like to use an inventory system that minimizes inventory cost. The restaurant has figured that the most economical order size or EOQ is approx. 409 (rounding up the decimals). Suppose that things have become uncertain and that customer demand is no more constant. Customer demand is now normally distributed with mean being the same as given in the problem description and standard deviation = 30 units per week. The supply source is still very reliable and as a result the lead time is constant. Find out the safety stock needed to achieve 95% customer service level.

He estimates that the value of his time spent ordering hammers is $75. a) What must be the unit cost of maintaining hammers for the current policy of the hardware store to be Optimal according to the EOQ model? b) If the distributor delivers an order for hammers in 5 business days (out of an average of 25 per month), what should be the reorder point, according to the EOQ model?arrow_forward
