Chapter 13, Problem 6E
Compute lead time
Jackson Fabricators Inc. machines metal parts for the automotive industry. Under the traditional manufacturing approach, the parts are machined through two processes: milling and finishing. Parts are produced in batch sizes of 40 parts. A part requires 6 minutes in milling and 8 minutes in finishing. The move time between the two operations for a complete batch is 5 minutes.
Under the lean philosophy, the part is produced in a cell that includes both the milling and finishing operations. The operating time is unchanged; however, the batch size is reduced to 5 parts and the move time is eliminated.
Determine the value-added, non-value-added, and total lead times, and the value-added ratio under the traditional and lean manufacturing methods. Round percentages to one decimal place.

- Bienestar Inc., has the following departmental structure for producing a well-known multivitamin: A consultant designed the following cellular manufacturing structure for the same product: The times above the processes represent the time required to process one unit of product. Required: 1. Calculate the time required to produce a batch of 15 bottles using a batch-processing departmental structure. 2. Calculate the time to process 15 units using cellular manufacturing. 3. How much manufacturing time will the cellular manufacturing structure save for a batch of 15 units?arrow_forwardHealthway uses a process-costing system to compute the unit costs of the minerals that it produces. It has three departments: Mixing, Tableting, and Bottling. In Mixing, at the beginning of the process all materials are added and the ingredients for the minerals are measured, sifted, and blended together. The mix is transferred out in gallon containers. The Tableting Department takes the powdered mix and places it in capsules. One gallon of powdered mix converts to 1,600 capsules. After the capsules are filled and polished, they are transferred to Bottling where they are placed in bottles, which are then affixed with a safety seal and a lid and labeled. Each bottle receives 50 capsules. During July, the following results are available for the first two departments (direct materials are added at the beginning in both departments): Overhead in both departments is applied as a percentage of direct labor costs. In the Mixing Department, overhead is 200 percent of direct labor. In the Tableting Department, the overhead rate is 150 percent of direct labor. Required: 1. Prepare a production report for the Mixing Department using the weighted average method. Follow the five steps outlined in the chapter. Round unit cost to three decimal places. 2. Prepare a production report for the Tableting Department. Materials are added at the beginning of the process. Follow the five steps outlined in the chapter.

Each manufacturing cell is dedicated to the production of a single product or major subassembly. One cell, dedicated to the production of mopeds, has four operations: machining, finishing, assembly, and qualifying (testing). The machining process is automated, using computers. In this process, the model’s frame and engine are constructed. In finishing, the frame is sandblasted, buffed, and painted. In assembly, the frame and engine are assembled. Finally, each model is tested to ensure operational capability. For the coming year, the moped cell has the following budgeted costs and cell time (both at theoretical capacity): Budgeted conversion costs $5,541,120 Budgeted materials $18,668,000 Cell time 35,520 Theoretical output 17,760 models During the year, the following actual results were obtained: Actual conversion costs $5,541,120 Actual materials $4,009,000 Actual cell time…arrow_forwardWilliams Optical Inc. is considering a new lean product cell.
