Economic production quantity. This type of problem can be recognized when a production rate (p) Problem 2is given in addition to the basic EOQ information. Use Formula 13–5 to compute the optimal runquantity. Production (run) time is Q/p. Imax is (Q/p)(p – u). The time between the end of one run andthe start of the next is (Imax)/u – setup time.The Dine Corporation is both a producer and a user of brass couplings. The firm operates 220days a year and uses the couplings at a steady rate of 50 per day. Couplings can be produced at a rateof 200 per day. Annual storage cost is $2 per coupling, and machine setup cost is $70 per run.a. Determine the economic run quantity.b. Approximately how many runs per year will there be?c.

[item no. 11] In a single period inventory model, the demand is assumed to follow a normal distribution. The value of ML/(ML+MP) is 0.6. The company used marginal analysis with the normal distribution to determine the optimal stocking level X*. If the mean demand is 100, then X* a. is less than 100 b. is equal to 100 c. cannot be determined from the information given d. is greater than 100
The maintenance department of a large hospital uses about 816 cases of liquid cleanserannually. Ordering costs are $12, carrying costs are $4 per case a year, and the new priceschedule indicates that orders of less than 50 cases will cost $20 per case, 50 to 79 caseswill cost $18 per case, 80 to 99 cases will cost $17 per case, and larger orders will cost $16per case. Determine the optimal order quantity and the total cost.
Single-period. This type of problem can be recognized when a probability distribution or empirical Problem 8distribution for demand for a “perishable” item is given along with unit shortage and excess costs, orinformation that can be used to calculate them. Use these steps to solve the problem:1. Compute the optimal service level using Formula 13–17.2. If the given distribution is uniform or normal, use that to obtain the exact stocking level.3. If the distribution is Poisson or empirical, SL will fall between two cumulative frequencies.Round up to the higher frequency to find the optimal stocking level. Note: If the distribution isempirical, first obtain the cumulative frequencies or probabilities.A firm that installs cable TV systems uses a certain piece of equipment for which it carries two spareparts as optimal.

Problem 20-40 (Algo) In the past, Taylor Industries has used a fixed−time period inventory system that involved taking a complete inventory count of all items each month. However, increasing labor costs are forcing Taylor Industries to examine alternative ways to reduce the amount of labor involved in inventory stockrooms, yet without increasing other costs, such as shortage costs. Here is a random sample of 20 of Taylor's items.

A warehouse has an end-of-period capacity of 3 units.During a period in which production takes place, a setupcost of $4 is incurred. A $1 holding cost is assessed against each unit of a period’s ending inventory. Also, a variableproduction cost of $1 per unit is incurred. During eachperiod, demand is equally likely to be 1 or 2 units. Alldemand must be met on time, and b .8. The goal is tominimize expected discounted costs over an infinite horizon. a Use the policy iteration method to determine an op-timal stationary policy. b Use linear programming to determine an optimalstationary policy.c Perform two iterations of value iteration.

A local outdoor vegetable stand has exactly 1,000 square feet of space to displaythree vegetables: tomatoes, lettuce, and zucchini. The appropriate data for theseitems are given in the following table.ItemTomatoes Lettuce ZucchiniAnnual demand 850 1,280 630(in pounds)Cost per pound $0.29 $0.45 $0.25The setup cost for replenishment of the vegetables is $100 in each case, and thespace consumed by each vegetable is proportional to its costs, with tomatoes requiring 0.5 square foot per pound. The annual interest rate used for computingholding costs is 25 percent. What are the optimal quantities that should be purchased of these three vegetables?
