Concept explainers
a
To determine:
Inventory at the end of each month assuming excess demand are back − ordered.
Introduction:
Demand of any product is the total units of product demanded by a consumer at a given price during a given period of time.
b
To determine:
Stock − out cost when excess demand at the end of each month is lost and when excess demand at the end of each month is back ordered.
Introduction:
Stock out cost is the income which is unearned due to shortage in inventory.
c
To determine:
Stock out cost incurred during six months when demand is fulfilled on a first − come, first basis.
Introduction:
Stock out cost is the income which is unearned due to shortage in inventory.
d
To determine:
Circumstances under which cost criteria is most appropriate.
Introduction:
Stock out cost is the income which is unearned due to shortage in inventory.

- The chapter presented various approaches for the control of inventory investment. Discuss three additional approaches not included that might involve supply chain managers.arrow_forwardDemand for an item is at the rate of 200 units per day. Stock will be replenished immediately upon order. Each order made will be charged a preparation cost of RM100.00, while a unit of goods that is kept in stock for a day will be charged a cost of RM0.50. Shortages are allowed to occur at a cost of RM3.00 for each unit of goods that are reduced for a day. Determine(i) the optimum order quantity(ii) the maximum allowable deficit size.arrow_forward13.13 The TransCanada Lumber Company and Mill processes 10,000 logs annually, operating 250 days per year. Immediately upon receiving an order, the logging company's supplier begins delivery to the lumber mill at the rate of 60 logs per day. The lumber mill has determined that the ordering cost is $1600 per order, and the cost of carrying logs in inventory before they are processed is $15 per log on an annual basis. Determine the following: a. The optimal order size b. The total inventory cost associated with the optimal order quantity c. The number of operating days between orders d. The number of operating days required to receive an orderarrow_forward

- Average Inventory Calculation—Fixed–Order Quantity ModelSuppose the following item is being managed using a fixed–order quantity model with safety stock.Annual demand (D) = 1,000 unitsOrder quantity (Q) = 300 unitsSafety stock (SS) = 40 unitsWhat are the average inventory level and inventory turn for the item?arrow_forwardThe following data are for an inventory item in which the EOQ model applies: Given: D = 10,000 units (annual demand) R = P10 per unit P = P500 per order C = 25% 0f average inventory Find: a. the number of orders per year b. the economic order quantity (EOQ) c. the amount in pesos per order d. the number of days interval between orders e. the total inventory costsarrow_forwardUsing the same information, how do I: Determine the total inventory-related costs associated with the optimal ordering policy (do not include the cost of the coal). and If 5 days of lead time are required to receive an order of coal, how much coal should be on hand when an order is placed?arrow_forward
- Provide two possible reasons for using the fixed-order-interval model. Give an example for each reason.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_forwardFor 8.4, suppose that Noname has 23,000 DRAM chips in inventory. It anticipates receiving a lot of 3,000 chips in week 3 from another firm that has gone out of business.At the current time, Noname purchases the chips from two vendors, A and B. A sells the chips for less, but will not fill an order exceeding 10,000 chips per week.a. If Noname has established a policy of inventorying as few chips as possible, what order should it be placing with vendors A and B over the next six weeks?b. Noname has found that not all the DRAM chips purchased function properly. From past experience it estimates an 8 percent failure rate for the chips purchased from vendor A and a 4 percent failure rate for the chips purchased from vendor B. What modification in the order schedule would you recommend to compensate for this problem?arrow_forward
