Same problem statement: Weekly demand for DVD-Rs at a retailer is normally distributed with a mean of 1,000 boxes and a standard deviation of 150. Currently, the store places orders to the supplier, with a reorder point of 4,200 boxes. The order quantity to the supplier is fixed at 5,000 boxes. Replenishment lead time is 4 weeks, fixed order cost per order is $100, each box costs the retailer $10, and the inventory holding cost is 25% per year. Assume 50 weeks in a year. Given the problem parameters, what is the optimal order quantity the retailer should order? Numeric Response 2040 a < Prev 4 of 5 Next >

St. John's Brewery (SJB) is getting ready for a busy tourist season. SJB wants to either increase production or produce the same amount as last year, depending on the demand level for the coming season. SJB estimates the probabilities for high, medium and low demands as 0.32, 0.31, and 0.37 respectively, on the basis of the number of tourists forecasted by the local recreational bureau. If SJB increases production, the expected profits corresponding to high, medium and low demands are $800,000, $400,000 and $100,000 respectively. If SJB does not increase production, the expected profits are $550,000, $325,000 and $200,000 respectively. (NOTE: Text answers are case sensitive and the value of different parts of this question is indicated in square brackets [*/*]) Construct a decision tree for SJB. On the basis of the EV, what should SJB do? What is the expected value of increasing production? What is the expected value of not increasing production? Should SJB increase production (enter…
A film processing service monitors the quality of the developing process with light-sensitive equipment. The accuracy measure is a number with a target value of zero. Suppose that an X- chart with subgroups of size five is used to monitor the process and the control limits are UCL = 1.5 and LCL = -1.5. Assume that the estimate for the process mean is zero and for the process standard deviation is 1.30.a. What is the value of α for this control chart?b. Find the UCL and LCL based on three-sigma limits.c. Suppose that the process mean shifts to 1. What is the probability that the shift is detected on the first subgroup after the shift occurs?
(c) The price of a 14 oz cup of coffee in Sunshine cafés is a random variable C with an expected value of $3.00 and a standard deviation of $1. At any given shop, the price doesn't vary, but it varies independently across shops. Tomorrow morning, you plan to buy two 14 oz cups of coffee from the same shop while your friend plans on buying two from two different shops. (i) How much do you expect to spend on coffee tomorrow and with what standard deviation? (ii) How much do you expect your friend to spend and with what standard deviation? (iii) Who do you think has a better idea and why?
A 28- year- old man pays $158 for one year life insurance policy with coverage of $110,000. If the probability he will live through the year is 0.9994, what is the expected value for the insurance policy?
A distribution company purchases two parts from the same supplier. When the company places an order there is a common procurement cost of $1750, in addition to $300 (Product I) and $100 (Product II) of individual procurement costs. Product I has a weekly demand of 500 units with a standard deviation of 50 units, Product I values $200, target CSL is 94%, and lead time is one month. Product II has a weekly demand of 60 units with a standard deviation of 15 units, each Product II values $1200, target CSL is 99%, and lead time is 3 months. The company uses 24% as the inventory holding rate per year (1 year is 52 weeks or 12 months) • Assuming each product is individually ordered using periodic review policy, compute T*, M*, and TC of Product I and II individually. . Assuming these products are jointly replenished, what will be the T*, M₁, M₁, TC? What is the amount of savings when products are jointly ordered compared to individual ordering?

The management of Brinkley Corporation is interested in using simulation to estimate the profit per unit for a new product. The selling price for the product will be $45 per unit. Probability distributions for the purchase cost, the labor cost, and the transportation cost are estimated as follows: Procurement Cost($) 10 $ 11 12 Probability 0.25 0.45 0.30 Labor Cost ($) 20 22 24 25 Probability 0.10 0.25 0.35 0.30 Transportation Cost ($) 3 5 (a) Compute profit per unit for the base-case, worst-case, and best-case scenarios. Base Case using most likely costs Profit = $ /unit Worst Case Profit = $ /unit Best Case Profit = $ /unit Probability 0.75 0.25 (b) Construct a simulation model to estimate the mean profit per unit. (Use at least 1,000 trials.) (c) Why is the simulation approach to risk analysis preferable to generating a variety of what-if scenarios? Simulation will provide ---Select--- of the profit per unit values which can then be used to find ---Select--- ◆ of an unacceptably low…

SJB wants to either increase production or produce the same amount as last year, depending on the demand level for the coming season.
