Help need. management accounting Lebar Daun Sdn Bhd is planning to use the economic order quantity model to determine the optimal order levels of raw materials. Material Z is consumed evenly over the year and the current usage is 120,000 units. The material is purchased in boxes and each box contains 12 units of material Z, at a price of RM252 per box. A safety stock of 200 boxes is kept. The cost of placing and handling orders is estimated to be RM6,300, which is based cost incurred for similar orders that have already made. The cost of RM6,300 was for 30 orders. The inflation of 2 per cent should be added to the above ordering costs. Besides, the company estimates to be charged the transporation cost of RM15 per order. It should be assumed that ordering costs change in proportion to the number of orders place. Other costs which relate to material Z such as insurance, interest and space costs for a year, were calculated at 15 % of the purchase price. Required: a. Calculate the order…
As with other products, Fisher-Price faces the decision of how many Weather Teddy units to order for the comingholiday season. Members of the management team suggested order quantities of 15,000, 18,000, 24,000, or28,000 units. The wide range of order quantities suggested indicates considerable disagreement concerning themarket potential. The product management team asks you for an analysis of the stock-out probabilities forvarious order quantities, an estimate of the profit potential, and to help make an order quantity recommendation.Fisher-Price expects to sell Weather Teddy for $24 based on a cost of $16 per unit. If inventory remains afterthe holiday season, Fisher-Price will sell all surplus inventory for $5 per unit. After reviewing the sales historyof similar products, Fisher-Price’s senior sales forecaster predicted an expected demand of 20,000 units with a.95 probability that demand would be between 10,000 units and 30,000 units. Question: One of Fisher-Price’s managers felt…
A jewelry manufacturer is creating a routine order schedule for some new products: J66 and J67. J66 can be ordered any time. J67 is set up to be ordered every 4 weeks. The company is closed 2 weeks out of a 52 week year otherwise it is open. Given the following, show me the calculation (I have provided the final answer) the questions at the end: J66 acceptable stockout risk = 2.5%, lead time = 2 weeks, ordering cost =$70, annual holding cost = 30%, unit cost =$15, standard deviation = 4 units per week, and average weekly demand is 60 units. J67 acceptable stockout risk = 2.5%, lead time = 2 weeks, ordering cost =$30, annual holding cost = 30%, unit cost =$20, standard deviation = 5 units per week, and average weekly demand is 70 units. I know the reorder point for j67 is 153 units on hand. 1) Show me the math to come up with the 153 units answer. 2) What is the reorder point for the J66? (I know the answer is 306 units so show me the calculation), 3) If the J67 has 110 units on…

Algro Inc. keeps a wide range of parts and materials on hand for use in its production processes. Management has recently had difficulty managing parts inventory as demand for its finished goods has increased; they frequently run out of some critical parts while having an endless supply of others. They would like to classify their parts inventory according to the ABC approach to better control inventory. The following is a list of parts, along with their annual usage and unit value: Item Annual Unit Item Annual Unit Number Usage Cost Number Usage Cost 1 36 $350 2 510 30 3 50 23 4 300 45 5 18 1900 6 500 8 7 710 4 8 80 26 9 344 28 10 67 440 11 510 2 12 682 35 13 1216 95 50 14 10 3 15 820 1 KARAN2222222222 16 60 $610 17 120 20 18 270 15 19 45 50 20 19 3200 21 910 3 12 4750 23 30 2710 24 24 1800 25 870 105 26 244 30 27 750 15 28 45 110 29 46 160 30 165 25 a.

Birka Styles & Co is introducing a new line of beachwear for their retail stores. The manager needs to decide how many lots of the new beachwear to order for their stores. The marketing came up with a payoff table (see below) considering information about the price, projected sales level, and cost of inventory and ordering. DEMAND Order size Low Medium High 1 lot 12,000 15,000 15,000 2 lots 9,000 25,000 35,000 3 lots 6,000 35,000 60,000 The owner found out that: P(Low demand) = 1/3; P(Med demand) = 1/2; P(High demand) = 1/6. Which of the following decision is NOT true? A)The best decision is to order 3 lots for a payoff of $29,500. The probabilities gave me enough information to perform a Laplace approach. B)The best decision is to order 3 lots for a payoff of $29,500. The probabilities gave me enough information to perform the EMV approach. C)The EVPI is $2,000. D)The EVwPI is $31,500.
