Use the following information for Exercises 5-44 through 5-46: The following six situations at Diviney Manufacturing Inc. are independent. a. A manual insertion process takes 30 minutes and 8 pounds of material to produce a product. Automating the insertion process requires 15 minutes of machine time and 7.5 pounds of material. The cost per labor hour is 12, the cost per machine hour is 8, and the cost per pound of materials is 10. b. With its original design, a gear requires 8 hours of setup time. By redesigning the gear so that the number of different grooves needed is reduced by 50%, the setup time is reduced by 75%. The cost per setup hour is 50. c. A product currently requires 6 moves. By redesigning the manufacturing layout, the number of moves can be reduced from 6 to 0. The cost per move is 20. d. Inspection time for a plant is 16,000 hours per year. The cost of inspection consists of salaries of 8 inspectors, totaling 320,000. Inspection also uses supplies costing 5 per inspection hour. The company eliminated most defective components by eliminating low-quality suppliers. The number of production errors was reduced dramatically by installing a system of statistical process control. Further quality improvements were realized by redesigning the products, making them easier to manufacture. The net effect was to achieve a close to zero-defect state and eliminate the need for any inspection activity. e. Each unit of a product requires 6 components. The average number of components is 6.5 due to component failure, requiring rework and extra components. Developing relations with the right suppliers and increasing the quality of the purchased component can reduce the average number of components to 6 components per unit. The cost per component is 500. f. A plant produces 100 different electronic products. Each product requires an average of 8 components that are purchased externally. The components are different for each part. By redesigning the products, it is possible to produce the 100 products so that they all have 4 components in common. This will reduce the demand for purchasing, receiving, and paying bills. Estimated savings from the reduced demand are 900,000 per year. 5-44 Nonvalue-Added Costs Refer to the information for Diviney Manufacturing on the previous page. Required: Estimate the nonvalue-added cost for each situation.
Pratt Company produces two replacement parts for a popular line of Blu-ray disc players: Part A and Part B. Part A is made up of two components, one manufactured internally and one purchased from external suppliers. Part B is made up of three components, one manufactured internally and two purchased from suppliers. The company has two processes: fabrication and assembly. In fabrication, the internally produced components are made. Each component takes 20 minutes to produce. In assembly, it takes 30 minutes to assemble the components for Part A and 40 minutes to assemble the components for Part B. Pratt Company operates one shift per day. Each process employs 100 workers who each work eight hours per day. Part A earns a unit contribution margin of 20, and Part B earns a unit contribution margin of 24 (calculated as the difference between revenue and the cost of materials and energy). Pratt can sell all that it produces of either part. There are no other constraints. Pratt can add a second shift of either process. Although a second shift would work eight hours, there is no mandate that it employ the same number of workers. The labor cost per hour for fabrication is 15, and the labor cost per hour for assembly is 12. Required: 1. Identify the constraints facing Pratt, and graph them. How many binding constraints are possible? What is Pratts optimal product mix? What daily contribution margin is produced by this mix? 2. What is the drummer constraint? How much excess capacity does the other constraint have? Assume that a 1.5-day buffer inventory is needed to deal with any production interruptions. Describe the drum-buffer-rope concept using the Pratt data to illustrate the process. 3. Explain why the use of local labor efficiency measures will not work in Pratts TOC environment. 4. Suppose Pratt decides to elevate the binding constraint by adding a second shift of 50 workers (labor rates are the same as those of the first shift). Would elevation of Pratts binding constraint improve its system performance? Explain with supporting computations.
Computador has a manufacturing plant in Des Moines that has the theoretical capability to produce 243,000 laptops per quarter but currently produces 91,125 units. The conversion cost per quarter is 7,290,000. There are 60,750 production hours available within the plant per quarter. In addition to the processing minutes per unit used, the production of the laptops uses 10 minutes of move time, 20 minutes of wait time, and 5 minutes of rework time. (All work is done by cell workers.) Required: 1. Compute the theoretical and actual velocities (per hour) and the theoretical and actual cycle times (minutes per unit produced). 2. Compute the ideal and actual amounts of conversion cost assigned per laptop. 3. Calculate MCE. How does MCE relate to the conversion cost per laptop?

Determine the resin materials cost per foot of finished product for each month. Round to the nearest whole cent. b. Determine the ratio of the number of resin pounds output in conduit by the number of pounds input into the process for each month. Round percentages to one decimal place. c. Interpret the resin materials cost per foot for the three months. Use the information in (a) and (b) to explain what is happening. d. Determine the conversion cost per foot of finished product for each month and interpret the result.
