- 1. Calculate Economic Order Quantity (EOQ), number of orders, annual ordering costs, annual carrying costs and total inventory costs from the following: Annual consumption: 6000 units ; Cost of placing one Order: RO 60 Carrying cost per unit: RO 22. Find out the EOQ, Annual ordering cost and annual holding cost from the following information. The demand is 19500 units per year, holding cost is RO 4 per unit for a year and ordering cost is RO 25 order. 3. Find out the ordering cost from the following information, Annual demand is 240 units, holding cost RO 4 per unit for a year and EOQ is 60 units.Norris Harrell’s Computer Store in San Fernando sells a printer for $200. The annual demand for this is 600 units, with a standard deviation of 1.5 units daily. The holding cost is $20, while the cost of ordering is $60 per order. Currently the company is ordering 12 times per year. There are 250 working days per year and the lead time is 10 days. a. Given the current policy of ordering, what is the total ordering and holding costs? b. If the company uses the absolute best inventory policy, what would be the total ordering and holding costs?Consider again the kitty litter ordering policy for Sam’s Pet Hotel in Problem 13. Suppose that the weekly demand forecast of 90 bags is incorrect and actual demand averages only 60 bags per week. How much higher will total costs be, owing to the distorted EOQ caused by this forecast error? Suppose that actual demand is 60 bags but that ordering costs are cut to only $6 by using the Internet to automate order placing. However, the buyer does not tell anyone, and the EOQ is not adjusted to reflect this reduction in S. How much higher will total costs be, compared to what they could be if the EOQ were adjusted?
- The carrying cost curve and ordering cost curve of Bulldogs Inc.’s inventory intersect at 3,500 units. What is the total annual cost of inventory given that the annual demand is 75,000 units and the carrying cost per unit per year is P12?Palin's Muffler Shop has one standard muffler that fits a large variety of cars.

Use the information in the following table to determine the optimal inventory target level (or order-up-to level). Ordering cost Service probability Annual demand 3,750 mufflers $ 60 92 % per order mufflers per working day per muffler % of item value working days Standard deviation of daily demand Item cost $39.00 working days per year Lead time 3 Working days Annual holding cost Review period 31 250 20 a. What is the optimal target level (order-up-to level)? (Use Excel's NORMSINV() function to find the correct critical value for the given a-level. Do not round intermediate calculations.

If the service probability requirement is 92 percent, the optimal target level will: O Stay the same Decrease O…BIKO is a bike retailer located in the outskirts of Paris. BIKO purchases bikes from PMX in orders of 250 bikes which is the current economic order quantity. PMX is now offering the following bulk discounts to its customers: 2% discount on orders above 200 units 4% discount on orders above 500 units 6% discount on orders above 600 units BIKO is wondering if the EOQ model is still the most economical and whether increasing the order size would actually be more beneficial. Following information is relevant to forming the decision: Annual demand is 5000 units Ordering cost is $100 per order Annual holding cost is comprised of the following: 5% insurance premium for the average inventory held during the year calculated using the net purchase price Warehousing cost of $6 per unit Purchase price is $200 per unit before discount (Hint: We need to compare the total inventory cost of the order quantities at the various discount levels with that of the economic order quantity)
- Henry Crouch's law office has traditionally ordered inkrefills 60 units at a time. The firm estimates that carrying cost is 40%of the $ 10 unit cost and that annual demand is about 240 units peryear. The assumptions of the basic EOQ model are thought to apply.a) For what va lue of ordering cost would its action be optimal?b) If the true ordering cost turns out to be much greater than youranswer to (a), what is the impact on the firm's ordering policy?The Co-op in problem 6 has discovered that it should establish a safety stock for its sweatshirts. It wants to use a reorder point system with a two-week lead time. The demand over a two-week interval has an average of 450 units and a standard deviation of 250 units.a. What reorder point should the Co-op establish to ensure a 95 percent service level for each order placed?b. What reorder point should be established to ensure that no more than one stockout occurs in the course of a year?c. How much average inventory will the Co-op carry for part b? Include both cycle inventory and safety stock in your answer.d. How often will the Co-op turn over its inventory, using the results from part c?The maintenance department of a large hospital uses about 816 cases of liquid cleanser annually. Ordering costs are $12, carrying costs are $4 per case a year, and the new price schedule indicates that orders of less than 50 cases will cost $20 per case, 50 to 79 cases will cost $18 per case, 80 to 99 cases will cost $17 per case, and larger orders will cost S16 per case. Determine the optimal order quantity and the total cost Show your result on diagram with order quantity on X axis and cost on Y axis.
