A firm experiences demand with a mean of 100 units perday. Lead time demand is normally distributed, with a meanof 1,000 units and a standard deviation of 200 units. It costs$6 to hold one unit for one year. If the firm wants to meet90% of all demand on time, what will be the annual cost ofholding safety stock? (Assume that each order costs $50.)
If the target in-stock probability increases, then the expected time between stockouts: a. increases.b. remains the same.c. decreases.d. could increase or decrease.
Change the ordering simulation so that emergencyorders are never made. If demand in any week isgreater than supply, the excess demand is simplylost. Simulate the same (s, S) policies as in theexample.

- Please do not give solution in image format thanku Deltic sells this component for 55 per unit with a 4-month delivery lead time. Assume Deltic covers all transportation and related processing until delivery. TCX’s demand forecast for the upcoming selling season (12 months) is a normal distribution with mean 13500 and standard deviation 3736,4 . TCX sells each unit, after integrating their proprietary software, for 135. Assume that TCX uses a holding cost rate of 25 %, and any leftover units can be sold for 30 on average. Due to the long lead time and high minimum order quantity required, TCX is planning on a single order from Deltic to meet their needs in the next year. How many of these components should TCX order? Calculate the resulting expected annual profits for TCX.arrow_forwardDemand each period is normally distributed and an order-up-to model is used to decideorder quantities.

- Please do not give solution in image formate thanku. A product’s demand over (l + 1) periods is normally distributed with a mean of 100 and standard deviation of 10. Lead time is 2 periods. The order-up-to model is used to manage inventory. If in-stock probability stays at 99%, what will happen to expected on-hand inventory when expected demand increases to 200? A) It will increase. B) It will stay the same. C) It will decrease. D) It may either increase or decrease.arrow_forwardThe best quantity to order One of the formulas for inventorymanagement says that the average weekly cost of ordering, payingfor, and holding merchandise iswhere q is the quantity you order when things run low (shoes,TVs, brooms, or whatever the item might be); k is the cost ofplacing an order (the same, no matter how often you order); c isthe cost of one item (a constant); m is the number of items soldeach week (a constant); and h is the weekly holding cost per item(a constant that takes into account things such as space, utilities,insurance, and security).

One particular part, a popular brand of oil filter, is purchased by the warehouse for $1.50 each. It is estimated that the cost of order processing and reciept is a $100 per order. The company uses an inventory carrying charge based on 28 percent annual interest rate. The monthly demand for the filters follows a normal distribution with mean 280 and a standard deviation 77. Order lead time is assumed to be 5 months. Assume that if a filter is demanded when the warehouse is out of stock, then the demand is back-ordered and the cost assessed for each back-ordered demand is $12.80. Determine the following quantities: a. The optimal values of the order quantity and the reorder level. b. The average annual cost of holding, setup, and stock-out associated with this item assuming that an optimal policy is used. c. Evaluate the cost of uncertanity for this process. That is, compare the average annual cost…arrow_forward
