M&D Chemicals produces two products that are sold as raw materials to companies thatmanufacture bath soaps and laundry detergents.Based on an analysis of current inventory levels and potential demand for the coming month, M&D'smanagement specified that the combined production for products A and B must total at least 350gallons. Separately, a major customer's order for 125 gallons of product A must also be satisfied.Product A requires 2 hours of processing time per gallon, and product B requires 1 hour ofprocessing time per gallon. For the coming month, 600 hours of processing time are available.M&D's objective is to satisfy these requirements at a minimum total production cost. Productioncosts are $2 per gallon for product A and $3 per gallon for product B.Develop a Linear Programming Model to determine how many gallons of each product should beproduced. Based on your solution to the M&D Chemicals problem, what is the resulting Total Production cost ?

Scenario 3 Ben Gibson, the purchasing manager at Coastal Products, was reviewing purchasing expenditures for packaging materials with Jeff Joyner. Ben was particularly disturbed about the amount spent on corrugated boxes purchased from Southeastern Corrugated. Ben said, I dont like the salesman from that company. He comes around here acting like he owns the place. He loves to tell us about his fancy car, house, and vacations. It seems to me he must be making too much money off of us! Jeff responded that he heard Southeastern Corrugated was going to ask for a price increase to cover the rising costs of raw material paper stock. Jeff further stated that Southeastern would probably ask for more than what was justified simply from rising paper stock costs. After the meeting, Ben decided he had heard enough. After all, he prided himself on being a results-oriented manager. There was no way he was going to allow that salesman to keep taking advantage of Coastal Products. Ben called Jeff and told him it was time to rebid the corrugated contract before Southeastern came in with a price increase request. Who did Jeff know that might be interested in the business? Jeff replied he had several companies in mind to include in the bidding process. These companies would surely come in at a lower price, partly because they used lower-grade boxes that would probably work well enough in Coastal Products process. Jeff also explained that these suppliers were not serious contenders for the business. Their purpose was to create competition with the bids. Ben told Jeff to make sure that Southeastern was well aware that these new suppliers were bidding on the contract. He also said to make sure the suppliers knew that price was going to be the determining factor in this quote, because he considered corrugated boxes to be a standard industry item. As the Marketing Manager for Southeastern Corrugated, what would you do upon receiving the request for quotation from Coastal Products?

Demand for stereo headphones and music players for joggers has caused Nina Industries to grow almost 50 percent over the past year. The number of joggers continues to expand, so Nina expects demand for headsets to also expand, because, as yet, no safety laws have been passed to prevent joggers from wearing them. Demand for the players for this year was as follows: MONTH DEMAND (UNITS) January 4,150 February 4,250 March 3,950 April 4,350 May 4,950 June 4,650 July 5,250 August 4,850 September 5,350 October 5,650 November 6,250 December 5,950 a. Using linear regression analysis, what would you estimate demand to be for each month next year? Using a spreadsheet, follow the general format in Exhibit 3.8. (Do not round intermediate calculations. Round your answers to 2 decimal places.) b. To be reasonably confident of meeting demand, Nina decides to use 3 standard errors of estimate for safety. How many additional units should be held to meet this…
1. Which of the following quantities has no effect on the first period’s ATP calculation? a) Current on-hand Inventory b) Booked customer orders for the first periods c) MPS quantity for the first period d) Forecasted demand for the first period 2. Which one of the following is an MRP lot-sizing rule that attempts to minimize the amount to minimize the amount of average inventory? a) Periodic order quantity (POQ), WITH P=2 b)Fixed order quantity (FOQ) c) Economic order quantity (EOQ) d)Lot for Lot (L4L). 3. Which of the following statements about lot-sizing rules for MRP is true? a) The periodic order quantity (POQ) rule generates a higher level of average inventory since it creates inventory remnants. b) FOQ is a dynamic lot-sizing rule which reduces the amount of inventory, by doing a better job of matching the order quantity to the projected on-hand inventory quantity. c) The lot for lot rule minimizes inventory investment but maximizes the number of orders placed. d) In…
Old Pueblo Engineering Contractors creates six-month “rolling” schedules, which are recomputed monthly. For competitive reasons (it would need to divulge proprietary design criteria, methods, and so on), Old Pueblo does not subcontract. Therefore, its only options to meet customer requirements are (1) work on regular time; (2) work on overtime, which is limited to 30 percent of regular time; (3) do customers’ work early, which would costan additional $5 per hour per month; and (4) perform customers’ work late, which would cost an additional $10 per hour per month penalty, as provided by their contract. Old Pueblo has 25 engineers on its staff at an hourly rate of $30. The overtime rate is $45. Customers’ hourly requirements for the six months from January to June are January 5000 February 4000 March 6000 April 6000 May 5000 June 4000 Develop an aggregate plan using a spreadsheet. Assume 20 working days in each month. 12. Alan Industries is expanding its product line to include three…

A bagel store orders cream cheese from three suppliers, Cheesy Cream Corp. (CCC), Super Smooth & Sons (SSS), and Bagel's Best Friend Co. (BBF). One month, the total order of cheese came to 100 tons. (The store does do a booming trade.) The costs were $80, $50 and $65 per ton from the three suppliers respectively, with the total cost amounting to $6,485. Given that the store ordered the same amount from CCC and BBF, how many tons of cream cheese were ordered from each supplier? Cheesy Cream Corp: Super Smooth & Sons: Bagel's Best Friend Co:

Franklin Tooling, Inc., manufactures specialty tooling for firms in the paper-making industry. All of their products are engineer-to-order and so the company never knows exactly what components to purchase for a tool until a customer places an order. However, the company believes that weekly demand for a few components is fairly stable. Component 135.AG is one such item. The last 26 weeks of historical use of component 135.AG is recorded below.
