A lawn and garden shop that is open for business seven days a week orders bags of grass seed every OTHER Monday. Lead time for seed orders is 5 days. On Monday, at ordering time, a clerk found 112 bags of seed in stock, and so he ordered 198 bags. Daily demand for grass seed is normally distributed with a mean of 15 bags and a standard deviation of four bags.The manager would like to know what the probability is that a grass seed stockout will occur before the next order arrives.
Please show a correct solution and answer. Thank you.
The owner and manager of a hardware store reevaluates his inventory policy for hammers. sells an average of 50 hammers a month, so you have placed purchase orders for 50 hammers with a distributor at a cost of $20 each at the end of each month. But the owner does not place all the store orders and find that this takes much of your time. 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?
A store has collected the following information on one of its products:Demand = 4,500 units/year Standard deviation of weekly demand = 12 units Ordering costs = $40/order Holding costs = $3/unit/year Cycle-service level = 90% (z for 90% = 1.28) Lead-time = 2 weeks Number of weeks per year = 52 weeks a.
If a firm uses the continuous review system to control the inventory, what would be the order quantity and reorder point?

- Demand for your product averages 20 units per day, with a standard deviation of 4. Your lead time is 5 days. What should your reorder point be, if you want to have a 95% chance of not running out of products during the lead time? With this reorder level, how much safety stock do you have?arrow_forwardSuppose the following item is being managed using a fixed-order quantity model with safety stock. Annual Demand = 100,000 units Order quantity = 30,000 units Safety stock = 4000 units What are the average inventory level and inventory turnover for this item?arrow_forwardInventory manager of a retail store wants to order plastic Easter eggs, demand for which is highly seasonal. Easter eggs come in a special value box (250 eggs per box). The manufacturer is located in China, so a long lead time required to receive the orders. After the order is placed, eggs will arrive just in time before the Easter Holiday. Therefore, if stocks out, the inventory manager will not be able to place a second order. The demand follows a normal distribution with a mean of 4,000 boxes and a standard deviation of 500 boxes. Each ordered special value box will cost $3 and will retail at $7. Leftover eggs will be salvaged at $2 per box after the Easter Holiday. Customer goodwill cost is estimated to be $0.934 for each lost sale. Find optimal order quantity and Expected Sold (Assume f_u(z)=0.25). Group of answer choices Cannot be calculated using the information given Q*=4,480 boxes, E[Sold]=4,000 boxes Q*=3,956 boxes, E[Sold]=4,480 boxes Q*=4,480 boxes, E[Sold]=3,956…arrow_forward
- sniparrow_forwardIt takes approximately 2 weeks (14 days) for an order of steel bolts to arrive once the order has been placed. 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 reorder point is? units (enter your response as a whole number).arrow_forwardA local store has a customer demand for a product. The daily demand assumed to be normally distributed with an average demand of 25 units with a standard deviation of 5 units.

- That One Book sells its books through The Witch and the Wardrobe bookstores. It costs That One Book $0.80 to print each book; it sells the book to The Witch and the Wardrobe for $2.50. The Witch and the Wardrobe then sells the books at retail for $6.00. Whatever doesn’t sell gets thrown away. Demand for the book each issue is normal with a mean of 5219 and a standard deviation of 1610. To give The Witch and the Wardrobe incentive to order more books, it proposes a revenue-sharing contract. Instead of selling the book to The Witch and the Wardrobe for $2.50, That One Book will sell its books to The Witch and the Wardrobe for only $1.00. However, for each book that The Witch and the Wardrobe sells at retail, The Witch and the Wardrobe must give $2.00 back to That One Book. With this revenue sharing agreement in place, what is the optimal order amount that will maximize The Witch and the Wardrobe expected profit?
