Your County has asked you to analyze the purchase of some dump trucks. Each truck wil cost $45,000 and have an operating and maintaining cost that starts at $15,000 the first year and increases by $ 2,000 per year. Assume the salvage value at the end of year is $9,000 and the interest rate is 12%. Estimate the equivalent annual cost of each truck.
Consider a product for which the average demand is 70 items per day (for 365 days per year) and the standard deviation of demand is 10 per day. The product value is $3, the order cost is $30 per order, and the inventory carrying cost is 20% per year. The stockout cost is $0.50 per unit short. The probability of being in stock is to be 99%. The supplier has an average lead time of 5 days with a standard deviation of 1.5 days.
a) Design a reorder point system using the 99% probability of being in stock and (i) state the policy (order size and when to order) and (ii) the total annual cost.
Policy (order size and when to order): ____________________________________
Total annual cost = ________
b) If the product must be ordered in multiples of 500 items, design a reorder point system using the 99% probability of being in stock and
(i) state the policy (order size and when to order),
(ii) the total annual cost,…
Barbara Flynn sells papers at a newspaper stand for $0.40. The papers cost her $0.30, giving her a $0.10 profit on each one she sells. From past experience Barbara
knows that:
a) 20% of the time she sells 150 papers.
b) 20% of the time she sells 200 papers.
c) 30% of the time she sells 250 papers.
d) 30% of the time she sells 300 papers.
Assuming that Barbara believes the cost of a lost sale to be $0.05 and any unsold papers cost her $0.30 and she orders 250 papers.
Use the following random numbers: 14, 4, 13, 9, and 25 for simulating Barbara's profit. (Note: Assume the random number interval begins at 01 and ends at 00.)
Based on the given probability distribution and the order size, for the given random number Barbara's sales and profit are (enter your responses for sales as integers
and round all profit responses to two decimal places):

- Assume the demand for a companys drug Wozac during the current year is 50,000, and assume demand will grow at 5% a year. If the company builds a plant that can produce x units of Wozac per year, it will cost 16x. Each unit of Wozac is sold for 3. Each unit of Wozac produced incurs a variable production cost of 0.20. It costs 0.40 per year to operate a unit of capacity. Determine how large a Wozac plant the company should build to maximize its expected profit over the next 10 years.arrow_forwardAlfa Inc. uses a 2-week periodic review for its notebook store inventory. Mean and standard deviation of weekly sales are 16 and 5 respectively. The lead time is 3 days. The mean and standard deviation of lead-time demand are 8 and 3.5 respectively. 1.What is the mean and standard deviation of demand during the review period plus the lead-time period? 2.Assuming that the demand has a normal probability distribution, what is the replenishment level that will provide an expected stockout rate of one per year? 3.lf there are 18 notebooks in the inventory, how many notebooks should be ordered?arrow_forwardConsider 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…arrow_forward
- 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?arrow_forwardA product with an annual demand of 800 units has Co = $20.00 and Ch = $6.

The storage cost is $3, the estimated backorder cost per gallon per month is $10. Assume that the demand follows a normal probability distribution, with an average of 100 gallons and a standard deviation of 4 gallons.arrow_forwardYou are managing a business that design products for specific medical purposes. Your potential demand is very short lived and uncertain. Your production cycle is very long which means you need to have the products ready in advance. If the demand for your product arises (only 30% chance), they will be sold well; if not, the products will remain unsold, and you will need to liquidate them for 500 each. You predict that the demand will be normally distributed with mean= 15000 and standard deviation= 7000. The production cost of your product is, on average, $5500. You will sell your product for $12500. Suppose you make 18000 products, and you get lucky and demand will occur this year. What is your expected profit?arrow_forward
