- A mail-order house uses 17,460 boxes a year. Carrying costs are 60 cents per box a year, and ordering costs are $96. The following price schedule applies. Number of Boxes Price per Box 1,000 to 1,999 $1.25 2,000 to 4,999 1.20 5,000 to 9,999 1.15 10,000 or more 1.10 a. Determine the optimal order quantity. (Round your answer to the nearest whole number.) Optimal order quantity __________ boxes b. Determine the number of orders per year. (Round your answer to 2 decimal places.)

Immediately upon receiving an order, the logging company’ssupplier begins delivery to the lumber mill at the rate of 60logs per day. The lumber mill has determined that the ordering cost is $1600 per order, and the cost of carrying logsin inventory before they are processed is $15 per log on anannual basis. Determine the following:a. The optimal order sizeb. The total inventory cost associated with the optimalorder quantityc. The number of operating days between ordersd. The number of operating days required to receive anordearrow_forwardConsider the supply : Last year, the retailer’s weekly variance of demand was 200 units.The variance of orders was 500, 600, 750, and 1,350 units for theretailer, wholesaler, distributor, and manufacturer, respectively.(Note that the variance of orders equals the variance of demandfor that firm’s supplier.)a) Calculate the bullwhip measure for the retailer.b) Calculate the bullwhip measure for the wholesaler.c) Calculate the bullwhip measure for the distributor.d) Calculate the bullwhip measure for the manufacturer. e) Which firm appears to be contributing the most to the bull-whip effect in this supply chain?arrow_forward
- A Mercedes dealer must pay $20,000 for each car purchased. The annual holding cost is estimated to be 25% of the dollar value of inventory. The dealer sells an average of 500 cars per year. He considers the lawsuit to be behind schedule but estimates that if he is short on one car in one year he will lose $20,000 worth of future profits. Each time the dealer places an order for automobiles, the ordering cost adds up to $10,000. Determine the distributor's optimal ordering policy. What is the maximum deficit that will occur? What is the total annual cost?arrow_forwardSkinnerís Fish Market buys fresh Boston bluefish daily for $5.60 per pound and sells it for $9.80 per pound. At the end of each business day, any remaining bluefish is sold to a producer of cat food for $3.80 per pound. Daily demand can be approximated by a normal distribution with a mean of 105 pounds and a standard deviation of 24 pounds. 1. What inventory model should be used to determine the order quantity to maximize the total expected proÖt? Why? 2. What is the service level under the optimal order quantity? 3. How much fresh Boston blueÖsh should Skinnerís Fish Market order so as to maximize the total expected proÖt?arrow_forwardHayes 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 as follows: (a) both ordering cost and carrying cost are 10% less that 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.arrow_forward
- The manager of a large electronics store wants to begin stocking a universal TV remote control device. Expected daily demand is 25 units (250 working days a year). The remote controls can be purchased from either supplier A or supplier B. Their price lists are as follows: Supplier A Supplier B Quantity Unit price Quantity Unit price 1-199 $14 1-149 $14.1 200-499 $13.8 150-349 $13.9 500+ $13.6 350+ $13.7 Ordering cost is $40 per order and annual holding cost is 25 percent of unit price. Lead time for either supplier is 10 days. Which supplier should be chosen and what kind of inventory ordering policy should be adopted?arrow_forwardThe Soon Company is a multinational company that purchases one of its crucial components from a supplier who offers quantity discounts to encourage larger order quantities. The supply chain manager of the company wants to determine the optimal order quantity to minimize the total annual inventory cost. The company’s annual demand forecast for the item is 850 units, the order cost is $10 per order, and the annual holding rate is 41 percent. The price schedule for the item is: Order Quantity Price per Unit ($) 1–150 6.00 151–350 5.50 351 and above 5.00 The first break point is 151 units and the second is 351 units.

- Helen needs 1159 kgs of chicken per day on average to make enchiladas for her store. The supplier charges a $67 delivery fee per order (which is independent of the order size) and $3.90 per kg. Helen’s annual holding cost is 20%. Assume 52 weeks per year and 7 days per week. If Helen wants to minimize inventory holding and ordering costs, how much chicken should she purchase with each order (in kgs)?
