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.
Discount-Mart, a major East Coast retailer, wants todetermine the economic order quantity (see Chapter 12 for EOQformulas) for its halogen lamps. It currently buys all halogenlamps from Specialty Lighting Manufacturers in Atlanta. Annualdemand is 2,000 lamps, ordering cost per order is $30, and annualcarrying cost per lamp is $12.
a) What is the EOQ?b) What are the total annual costs of holding and ordering(managing) this inventory?c) How many orders should Discount-Mart place with SpecialtyLighting per year?
