- Which of the following statements about the basic EOQ model is Ture? If the holding cost were to increase, the EOQ would reduce. If the ordering cost were to decrease, the EOQ would increase. If annual demand were to double, the EOQ would also double. If annual demand were to increase, the EOQ would reduce.The following statements refer to the Economic Order Quantity (EOQ) model. Which of the following are true? I. The EOQ is found by minimizing the total demand function. II. Total annual purchasing costs affects the EOQ. III. The EOQ model takes the timing of reordering into account.53. Average demand for a particular item is 1,200 units per year. It costs $100 to place an ordem for this item, and it costs $24 to hold one unit of this item in inventory for one year. If the fixed order-interval model is chosen in this instance, how often (on average) will this item be ordered a) Once a month b) Once every other month c) Twice a month d) Twice every three months e) Three times every two months 54. The EOQ model is most relevant for which one of the following? a) Ordering items with dependent demand b) Determination of safety stock c) Ordering perishable items d) Determining fixed interval ordering quantity e) Determining fixed order quantity 55.

- Henrique Correa's bakery prepares all its cakes between 4 A.M.and 6 A.M.so they will be fresh when customers arrive. Day-old cakes are virtually always sold, but at a 50% discount off the regular $8 price. The cost of baking a cake is $5,and demand is estimated to be normally distributed, with a mean of 25 and a standard deviation of 7. What is the optimal stocking level?Daily demand for a product is 10 units. The standard deviation of demand during the review and lead time is 20 units. The review period is 30 days and the lead time is 14 days. At the time of review there are 150 units in stock. If the probability of stockout should not exceed 2%, how many units should be ordered?Martina is in charge of ordering brake pads for an auto shop. The daily demand for brake pads is normally distributed with an average of 40 brake pads and a standard deviation of 8 break pads. Currently, it takes 4 days between when Martina places an order for new brake pads and when the order is received. Currently, Martina orders new break pads when there are 184 break pads left in stock. 1) What is the average demand during lead time? 2) What is the standard deviation of demand during lead time? 3)What is the service level provided by Martina's auto shop?
- 1. Suppose the demand of a product in a retail store is 800 per year and it occurs at a constant rate. Placement of an order of this product to an outside supplier by the store is 40 Dollar. The super market authority has calculated the inventory holding cost per unit per year as 90 cents. Assuming no occurrence of shortages of the product, find a) i. the minimal order quantity of the product from the outside supplier if the product is not allowed to sell during production. ii. the minimal number of orders per year. Explain whether the nearest integer number of orders per year is justified. iii. the cycle time of a lot in months. iv. the annual minimal total cost of ordering and inventory holding for that minimal order quantity. v. the reorder point if the lead time of delivering a lot is 2 days,? b) If the production rate of processing the product is 1200 per year and the set up cost per set up is 65 Dollar. If the selling of the product is allowed during production, determine i) the…Consider a two-tier supply chain with one manufacturer and one retailer whointeract in a single selling season. The manufacturer sells a product to the retailer, who in turn sells in the market. Demand E is uncertain with cumulative distribution function F (·)and probability density function f (·). Since the production lead time is much longer thanthe selling season, the retailer must place a single order before demand is realized and cannotreplenish her inventory during the season. The retailer sells the product at an exogenousand fixed retail price r. The manufacturer produces the product at a unit cost of c. Themanufacturer uses a linear sales rebate contract and determines the following contract terms:For each unit ordered, he charges the retailer a wholesale price w, and for each unit sold, hepays the retailer a rebate s. Assume that the product has zero salvage value at the end ofthe season, and the inventory holding cost during the season is…Unplanned inventory decreases: tend to result in a decrease in income. tend to result in an increase in real output. tend to further reduce production. signal that demand was weaker than expected.
- According to the EOQ and increase in interest rates would tend to....? A: increase the number of units ordered for inventory and increase the number of orders per year B: decrease the number of units ordered for inventory and reduce the number of orders per year C: decrease the number of units ordered for inventory and increase the number of orders per year D: increase the number of units ordered for inventory and reduce the number of orders per yearA manufacturing company faces an uncertain demand for its product at an average of 10,000 units per year. Selling price of the product is IDR. 1.500.000,-. The cost of holding per unit per year is estimated at ID. 350.000,-. Profit of the product is IDR. 300,000,- per unit. If the company could not meet the demand, then the profit will be lost. Ordering lead time is approximately 7 days, and the demand during lead time follows a uniform distribution of 30 to 200 units. a. Determine order quantity and reorder points to minimise the total cost b.Determine the review period and maximum inventory to minimise the total costWhat are the primary benefits of implementing the Wilson approach in inventory control?
