Summary Introduction
To determine: The Economic order quantity.
Introduction: Inventory management is the process of ordering, storing and using inventory of the company such raw material, components and finished goods. It governs the flow of goods from manufacturers to warehouse and to the point of sale. The key function is to maintain record of flow of new or returned products which enters or leaves the company.

Petromax Enterprises uses a continuous review policy to manage the inventory for one of its SKUs. The following information is available on the item. The firm operates 50 weeks in a year. Demand = 90,000 units/year Ordering Cost = $60/Order Holding Cost = $3/Unit/Order Lead Time = 10 weeks Standard Deviation of Weekly Demand = 200 units Suppose due to some recent changes to the target service level, they have determined the reorder point to be 20,000. If the inventory position of this SKU is currently 19,600, how many units should they order?
(Round your answer to the nearest whole number, if it has decimals. Input 0 if they should not order now.)
Cheryl Druehl has asked you to help her determinethe best ordering policy for a new product. The demand for thenew product has been forecasted to be about I ,000 units annually.To help you get a handle on the carrying and ordering costs,Cheryl has given you the list of last year's costs. She thought thatthese costs might be appropriate for the new product. She also told you that these data were compiled for 10,000 inventoryitems that were carried or held during the year. You havealso determined that 200 orders were placed last year. Your job as a new opera tions management graduate is to help Cheryl determinethe economic order quantity for the new product.
Hayes Electronics assumed with certainty that the ordering cost is $450 per order and the inventory carrying cost is $170 per unit per year. However, the inventory model parameters are frequently only estimates that are subject to some degree of uncertainty. Consider four cases of variation in the model parameters: (a) Both ordering cost and carrying cost are 10% less than originally estimated, (b) both ordering cost and carrying cost are 10% higher than originally estimated, (c) ordering cost is 10% higher and carrying cost is 10% lower than originally estimated, and (d) ordering cost is 10% lower and carrying cost is 10% higher than originally estimated. Determine the optimal order quantity and total inventory cost for each of the four cases. Prepare a table with values from all four cases and compare the sensitivity of the model solution to changes in parameter values.

- In the past, Taylor Industries 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 Taylor Industries to examine alternative ways to reduce the amount of labor involved in inventory stockrooms, yet without increasing other costs, such as shortage costs. Here is a random sample of 20 of Taylor's items.

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.

The pharmacist expects to sell 6000 packages of this antibiotic at a steady rate during the next year. She plans to place several orders of the same size spaced equally throughout the year.

Use this information to answer the following questions. a) Let x be the order quantity and r the number of orders placed during the year. Find the inventory cost (ordering cost plus carrying cost) in terms of x and r. b) Find the constraint function. c) Determine the economic order quantity that minimizes the inventory cost and then find the minimum inventory cost.

- Assume that JAO, Inc., a manufacturer of electronic test equipment, uses 14,400 units of an item annually. Its order cost is P500 per order, and the carrying cost is P10 per unit per year.

Sales of 10W40 grade premium oil average 20 cans per day. Inventory holding costs are $0.50 per can per year. Ordering costs are $10 per order. The lead time is two weeks. Backorders are not practical— the motorist drives away.a. Based on these data, choose the appropriate inventory model and calculate the economic order quantity and reorder point. Describe in a sentence how the plan would work. Hint: Assume demand is deterministic.b. The boss is concerned about this model because the demand really varies. The standarddeviation of demand was determined from a data sample to be 6.15 cans per day. Themanager wants a 99.5 percent service probability.

- Company XYZ makes bicycles. XYZ produces 400 bicycles a month. They must buy tires from a supplier at a cost of $20 per tire. The inventory holding cost rate is 15% and ordering costs $50 per order. Part i) Let’s assume that there is no shortage inventory allowed. Calculate optimal annual order quantity Calculate annual total inventory cost ^already have the answer for this one. Just input the whole question so it would make more sense. Part ii) Let’s assume that shortage inventory is allowed. With that being said, we know that the shortage cost per unit of item is $5 per year. <<this is the one that I am stuck on.

You decide to test one item and choose Michelin tires, XW size 185 × 14 BSW. A perpetual inventory system has been used, so you examine this as well as other records and come up with the following data: Cost per tire $35 each Holding cost 20 percent of tire cost per year Demand 1,000 per year Ordering cost $20 per order Standard deviation of daily demand 3 tires Delivery lead time 4 days Because customers generally do not wait for tires but go elsewhere, you decide on a service probability of 98 percent. Assume the demand occurs 365 days per year. Determine the order quantity. Note: Round your answer to the nearest whole number. Determine the reorder point.
