A drugstore uses fixed-order cycles for many of the items it stocks. The manager wants a service level of .99. The order interval is 12 days, and lead time is 4 days. Average demand for one item is 63 units per day, and the standard deviation of demand is 6 units per day.

- A printing company anticipates using 40,000 reams of paper at a uniform rate over the next year. Each time they place an order for X units of reams of paper, it is charged a flat fee of $200. Carrying costs are $4 per unit per year. A. use the formula for Economic Order Quantity to find out how many reams of paper they should purchase in each order. B. how many orders should they place over the year?arrow_forwardWhat is the relationship between the average inventory and the in-stock probability?a. The more the inventory, the lower the in-stock probability.b. There isn’t a definitive relationship—more inventory could mean a lower or a higherin-stock probability.c. The more the inventory, the higher the in-stock probability.arrow_forwardAt sejahtera.com, a large retailer of popular books, demand is constant at 32,000 books per year.

- It takes approximately 2 weeks (14 days) for an order ofsteel bolts to arrive once the order has been placed. The demandfor bolts is fa irly constant; on the average, the manager, MichelleWu, has observed that the hardware store sells 500 of these boltseach day. Because the demand is fairly constant, Michelle believesthat she can avoid stockouts completely if she orders the bolts atthe correct time. What is the reorder poin t?arrow_forwardJim's Job Shop buys two parts (Tegdiws and Widgets) for use in its production system from two different suppliers. The parts are needed throughout the entire 52-week year. Tegdiws are used at a relatively constant rate and are ordered whenever the remaining quantity drops to the reorder level. Widgets are ordered from a supplier who stops by every three weeks. Data for both products are as follows: a. What is the inventory control system for Tegdiws? Reorder quantity = 1,225 Reorder point = 824.24 b. Find the total inventory costs if using inventory policy. This is a case considering safety stock (Do not use Excel, show your work) Holding cost per unit per year is given as a percentage of item cost ITEM TEGDIW WIDGET Annual Demand 10,000 5,000 Holding cost (% of item cost) 20% 20% Set up or order cost $150.00 $25.00 Lead Time 4 weeks 1 week Safety stock 55 units 5 units Item cost $10.00 $2.00arrow_forwardAll EXCEPT which of the following statements about ABC analysis are TRUE? O In ABC analysis, inventory may be categorized by measures other than dollar volume. O ABC analysis suggests that all items require the same high degree of control. O ABC analysis categorizes on-hand inventory into three groups based on annual dollar volume. O ABC analysis is an application of the Pareto principle.arrow_forward
- A golf specialty wholesaler operates 50 weeks per year. Management is trying to determine an inventory policy for its 1-irons, which have the following characteristics: > Demand (D) = 2,000 units/year > Demand is normally distributed > Standard deviation of weekly demand = 2 units > Ordering cost = $30/order > Annual holding cost (H) = $5.00/unit > Desired cycle-service level = 85% > Lead time (L) = 4 weeks Refer to the standard normal table for z-values. a. If the company uses a periodic review system, P should be 3.87 weeks. (Enter your response rounded to the nearest whole number.) T should be units. (Enter your response rounded to the nearest whole number.)arrow_forwardA building materials stockist obtains its cement from a single supplier. Demandfor cement is reasonably constant throughout the year. Last year the company sold 2 000tonnes of cement. It estimates the costs of placing an order at around 25 MU each timean order is placed and charges inventory holding at 20% of purchase cost. The companypurchases cement at 60 MU per tonne.a) How much cement should the company order at a time?b) Instead of ordering EOQ, why not a order convenient 100 tonnes? Please mention formulas and do it in detail so I can understand.arrow_forwardConsider a two-stage plant-retailer supply chain. Lead time for orders is two weeks. Safety stock is equal to one week's demand, and future demand is estimated by the average of the past two weeks. 1. Develop production planning model (equations) for the retailer that states the order-up- to rule, and order quantities as a function of time. 2. Using a table format (Columns are Week, Starting retail inventory, On order, Order-up-to target, Order quantity, and Demand) track performance of the retailer for eight weeks if demand suddenly shifts from 100 units per week to 110 units per week starting in period 3 and stays at 110 to the end.arrow_forward
