In Problem 12 of the previous section, suppose that the demand for cars is normally distributed with mean 100 and standard deviation 15. Use @RISK to determine the best order quantityin this case, the one with the largest mean profit. Using the statistics and/or graphs from @RISK, discuss whether this order quantity would be considered best by the car dealer. (The point is that a decision maker can use more than just mean profit in making a decision.)
A manufacturer has a production facility that requires 15,604 units of component JY21 per year. Following a long-term contract, the manufacturer purchases component JY21 from a supplier with a lead time of 7 days. The unit purchase cost is $25.6 per unit. The cost to place and process an order from the supplier is $121 per order. The unit inventory carrying cost per year is 10.5 percent of the unit purchase cost. The manufacturer operates 250 days a year. Assume EOQ model is appropriate. If the manufacturer uses a constant order quantity of 2,640 units per order, what is the annual holding cost? Use at least 4 decimal places.

A retail outlet sells a seasonal product for $10 per unit. The cost of the product is $8 per unit. All units not sold during the regular season are sold for half the retail price in an end-of-season clearance sale. Assume that demand for the product is uniformly distributed between 200 and 800. What is the recommended order quantity? What is the probability that at least some customers will ask to purchase the product after the outlet is sold out? That is, what is the probability of a stock-out using your order quantity in part (a)? To keep customers happy and returning to the store later, the owner feels that stock-outs should be avoided if at all possible. What is your recommended order quantity if the owner is willing to tolerate a 0.15 probability of a stock-out?
Aboloway Company stocks a part that has a daily demand represented by the empirical distribution (shown in the table below). When restocking this part, the average lead time from the supplier is 3 days with a standard deviation of 0.5 days. The plant manager wants to determine how much safety stock to maintain for this part to ensure that stock-outs will not be incurred in more than 5.5% of the order cycles. Daily demand (d) in units Frequency 5 10 10 35 15 65 20 32 25 8 Total Observations = 150 3a. Find the mean and standard deviation for demand. 3b. Based on the information in problems 3 and 3a, what is the mean and standard deviation of demand during the lead time? 3c. Based on the information in problems 3, 3a, and 3b, how much safety stock should the plant manager maintain to ensure that stock-out will not be incurred in more than 5.5% of the order cycles?
The bullwhip effect (also known as the Forrester effect) is defined as the demand distortion that travels upstream in the supply chain from the retailer through to the wholesaler and manufacturer due to the variance of orders which may be larger than that of sales. What causes the bullwhip effect in supply chain? Demand forecast updating: Members of the supply chain updating their demand forecasting Order batching: Members of the supply chain rounding up or down the quantity of orders Price fluctuations: Usually driven by discounting resulting in larger quantities of purchases Rationing and gaming: Buyers and sellers delivering over or under their order quantities An example of the bullwhip effect Let’s consider a retailer sells on average 10 ice creams per day in the summer season. Following a heatwave the retailer's sales increase to 30 units per day, in order to meet this new demand, the retailer increases their demand forecast and places an increased order on the wholesaler…
A shop is planning an order for a popular Christmas festive season product. Demand for the product usually starts from first week of December till first week of January and reduces sharply thereafter. For this reason, and to stimulate sales for leftovers, the product is sold at a significantly reduced price from the second week of January to the fourth week of January. Any leftover after the fourth week of January goes waste. The table below gives past data on total demand for the period from first week of December to first week of January, and from second week of January to fourth week of January, together with their respective chances of occurrence. The product can be purchased at a wholesale price of GHS60 per unit for a pack containing 600 products, GHS57 per unit for a pack containing 800 products, and GHS52 per unit for a pack containing 1000 products. The shop plans to sell the product for GHS80 per unit from first week of December to first week of January, and at a reduced…

Answer questions 5 & 6 based on the following information. A weekly sports magazine publishes a special edition for the World Series. The sales forecast is for the number of copies to be normally distributed with a mean of 800,000 copies and a standard deviation of 60,000 copies. It costs $0.35 to print a copy, and the newsstand price is $1.95. Unsold copies will be scrapped. Your job is to calculate the number of copies that should be printed. First, calculate P(demand
You are starting a Christmas tree business. You can purchase trees from local farmers at $25 per tree. You are able to sell the trees at $75 per tree. Any leftover trees can be sold to the local wood chip company at $5 per tree. Assume that the demand follows a uniform distribution ~U(94,382). How many trees should you stock through the holiday season? Note: round your answer to the nearest whole number. Answer: 285 Check X
Monsanto sells genetically modified seed to farmers. It needs to decide how much seed to put into a warehouse to serve demand for the next growing season. It will make one quantity decision. It costs Monsanto $8 to make each kilogram (kg) of seed. It sells each kg for $45. If it has more seed than demanded by the local farmers, the remaining seed is sent overseas. Unfortunately, it only earns $3 per kg from the overseas market (but this is better than destroying the seed because it cannot be stored until next year). If demand exceeds its quantity, then the sales are lost—the farmers go to another supplier. As a forecast for demand, it will use a normal distribution with a mean of 300,000 and a standard deviation of 100,000. Round your answer to 2 digits after the decimal point if it is not an integer. Do NOT use comma in your numeric answers. Use excel for accurate numbers. Don't round until the end. Monsanto’s maximum profit for this seed is $[xa]. The underage cost is $[xb]. The…
