9. The Ace Manufacturing Company has orders for three similar products: Orders Product (units) A 2000 500 1200 B C Three machines are available for the manufacturing operations. All three machines can produce all the products at the same production rate. However, due to varying defect per- centages of each product on each machine, the unit costs of the products vary depending on the machine used. Machine capacities for the next week and the unit costs are as follows: Сараcity (units) Product Machine Machine A в C 1500 $1.00 $1.30 $1.10 $1.20 $1.40 $1.00 $0.90 $1.20 $1.20 1 1500 1000 3 Use the transportation model to develop the minimum cost production schedule for the products and machines.

The manager of a car wash must decide whether to have one or two wash lines. One line will mean a fixed cost of RM6000 a month, and two lines will mean a fixed cost of RM10500 a month. Each line would be able to process 15 cars an hour. Variable costs will be RM3 per car, and revenue will be RM5.95 per car. The manager projects an average demand of between 14 and 18 cars an hour. Would you recommend one or two lines? The car wash is open 300 hours a month.

An airline company must plan its fleet capacity and itslong-term schedule of aircraft usage. For one flight seg-ment, the average number of customers per day is 70,which represents a 65 percent utilization rate of the equipment assigned to the flight segment. If demand isexpected to increase to 84 customers for this flight seg-ment in three years, what capacity requirement should beplanned? Assume that management deems that a capacitycushion of 25 percent is appropriate.
QuestionByron Sports is a manufacturer of sportswear. It produces all of its products in one department using a process costing system.The information for the current month is as follows:Beginning work in process (30% complete as to conversion cost) 12,000 unitsUnits started 90,000 unitsUnits completed and transferred out ?Ending work in process (70% complete as to conversion) 8,000 unitsCosts:Beginning work-in-process direct materials $28,800Beginning work-in-process conversion $5,040Direct materials added during month $216,000Conversion costs incurred during the month $139,200Direct materials are added at the beginning of the process. Conversion costs are incurred uniformlythroughout the production process. Costing is handled on a FIFO basis Required:a. Prepare a production cost worksheet using 5 steps approach.b. Under what conditions would a process costing system be more appropriate than a job order costing system? Explain.
4. The Spencer Optics Company produces an inexpensive line of sunglasses. The manufacturing process consists of assembling two plastic lenses (produced by the firm's plastic molding depart- ment) into a finished frame (purchased from an outside supplier). The company is interested in using material requirements planning to schedule its operations and has asked you to prepare an example to illustrate the technique. The firm's sales manager has prepared a 10-week sales forecast for one of the more popular sunglasses (the Classic model) for your example. The forecast is 100 units per week. Spencer has customer orders of 110 units, 80 units, 50 units, and 20 units in weeks 1, 2, 3, and 4, respectively. The sunglasses are assembled in batches of 300 units. Presently, three such batches are sched- uled: one in week 2, one in week 5, and one in week 8. Complete the following time-phased record: Week hand 1 2 3 4 5 6 7 8 9 10 Classic Model On MPS Record Forecast Orders Projected available…
er A product line includes 8 different product styles, each consisting of 93 components. Assume that 9 processing operations are needed to produce each component on average with each operation taking an average 1.2 min, which includes setup time and part handling time. All operations need a production machine, and currently 25 machines are dedicated to this task. The plant operates 52 hours per week, 52 weeks a year. Determine the yearly production of each style in units (round downward). 63 504
d CE Additional Algo 5-11 Attrition Losses and Yields A process has three resources and two types of flows. The first flow has a demand of 20 units per day, and the second flow has a demand of 40 units per day. The first flow type visits all three resources, while the second flow type only visits the first and the third resources. The capacity is 100 units per day at the first resource, 40 units per day at the second resource, and 70 units per day at the third resource. 1. What is the demand total for each resource?

Charles Lackey operates a bakery in Idaho Falls, Idaho. Because of its excellent product and excellent location, demand has increased by 5555% in the last year. On far too many occasions, customers have not been able to purchase the bread of their choice. Because of the size of the store, no new ovens can be added. At a staff meeting, one employee suggested ways to load the ovens differently so that more loaves of bread can be baked at one time. This new process will require that the ovens be loaded by hand, requiring additional manpower. This is the only production change that will be made in order to meet the increased demand. The bakery currently makes 1,800 loaves per month. Employees are paid $8 per hour. In addition to the labor cost, Charles also has a constant utility cost per month of $800 and a per loaf ingredient cost of $0.35 Current multifactor productivity for 640 work hours per month =0.27loaves/dollar (round your response to three decimal places).
