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?
Green Grass Industries Limited (GGIL) has used a fixed-time period
inventory system that involved taking a complete inventory count of
all items each month. However, increasing labor costs, are forcing
GGIL, to examine alternative ways to reduce the amount of labor
involved in inventory stockrooms, yet without increasing other
costs, such a shortage costs. Table 10 is a random sample of 20
GGIL's items.

a) What would you recommend GGIL to do to cut back its labor
cost? (Illustrate using an ABC plan).
b) Item 18 is critical to continued operations at GGIL.
i. How would you recommend it be classified?
ii. Give the reason(s) for your
answer.
United Airlines has an agreement to buy jet fuel from Exxon. The goal is
to minimize total cost (i.e., ordering cost + holding cost). The annual
demand for fuel is 201,000 barrels. Exxon charges United $3740 to
process each order. United incurs a holding cost of $20 per barrel.
When purchasing using the EOQ (from last question), what is the order cycle
time (days between orders) for United?
Note: round your answer to the nearest 1 decimal place. For example,

- Dalia, the office manager of a desktop publishing outfit, stocks replacement toner cartridges for laser printers. Demand for cartridges is approximately 30 per year and is quite variable (Le., can be represented using the Poisson distribution). Cartridges cost $100 each and require three weeks to obtain from the vendor. Dalia uses a (Q, r) approach to control stock levels (a). If Dalia wants to restrict replenishment orders to twice per year on average, what batch size Q should she use? If she wants to ensure a service level (i.e., probability of having the cartridge in stock when 2 out of 2 needed) of at least 98 percent, what reorder point r should she use? (Hint: Use Table 2.6.(b). If Dalia is willing to increase the number of replenishment orders per year to six, how do Q and r change? Explain the difference in r.arrow_forwardFisk Corporation is trying to improve its inventory control system and has installed an online computer at its retail stores. Fisk anticipates sales of 112, 500 units per year, an ordering cost of $3 per order, and carrying costs of $1.20 per unit. a. What is the economic ordering quantity? b. How many orders will be placed during the year? c. What will the average inventory be? d. What is the total cost of ordering and carrying inventory?arrow_forward#5. Consider a product that is stocked using periodic review inventory policy. Orders are placed every 21 days, and shipment lead time is four days. Daily demand is normally distributed with a mean of 58 and standard deviation of 16; fulfillment policy is at 97%. You have to do the following: (b) If the current stock is 398, and we are about to place an order, how much do we order?.arrow_forward
- 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_forwardV1 A local furniture store sells an average of 40 tables per week. The store orders 80 tables each time, and the ordering cost is $1,600 per order. 1. How many weeks are there between two consecutive orders? 2.

Preparing an order and receiving a shipment of flour involves a cost of $10 per order. Annual holding costs are $75 per bag. Once an order for flour is placed, it takes six (6) days to receive the order from the flour factory. The bakery operates 350 days per year. Calculate the following: Economic Order Quantity Expected number of orders (Order Frequency) Average inventory The annual holding cost The annual ordering cost The total annual cost of inventory management Reorder point If holding costs were to increase by $9 per year, how much would that affect the minimum total annual cost?arrow_forward

Each converter requires exactly 5 tons of coal per day to operate, and the firm operates 360 days per year. The purchasing manager has determined that the ordering cost is $80 per order and the cost of holding coal is 20% of the average dollar value of inventory held. The purchasing manager has negotiated a contract to obtain the coal for $12 per ton for the coming year. a. Determine the optimal quantity of coal to receive in each order. (Ans: 1200 tons) b. Determine the total inventory-related costs associated with the optimal ordering policy (do not include the cost of the coal). (Ans: TC= $2880) c.

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_forward
