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 90 parts. A part requires 5 minutes in milling and 9 minutes in finishing. The move time between the two operations for a complete batch is 10 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. If required, round percentages to one decimal place.

Mabbut Company has the following departmental manufacturing layout for one of its plants: Required:1. Calculate the total time it takes to produce a batch of 10 units using the traditionaldepartmental manufacturing layout.2. Using cellular manufacturing, how much time is saved producing the same batch of10 units? Assuming the cell operates continuously, what is the production rate? Whichprocess controls this production rate?3. Assume the processing time of Welding is reduced to 6 minutes, while the times ofthe other processes stay the same. What is the production rate now, and how longwill it take to produce a batch of 10 units if the cell is in a continuous productionmode?
Lead Time ¡Sounds Inc. manufactures electronic stereo equipment. The manufacturing process includes printed circuit (PC) board assembly, final assembly, testing, and shipping. In the PC board assembly operation, a number of individuals are responsible for assembling electronic components into printed circuit boards. Each operator is responsible for soldering components according to a given set of instructions. Operators work on batches of 50 printed circuit boards. Each board requires 4 minutes of board assembly time. After each batch is completed, the operator moves the assembled boards to the final assembly area. This move takes 9 minutes to complete. The final assembly for each stereo unit requires 21 minutes and is also done in batches of 50 units. A batch of 50 stereos is moved into the test building, which is across the street. The move takes 20 minutes. Before conducting the test, the test equipment must be set up for the particular stereo model. The test setup requires 30…

Williams Optical Inc. is considering a new lean product cell. The present manufacturing approach produces a product in four separate steps. The production batch sizes are 45 units. The process time for each step is as follows: Step Time (in minutes) Process Step 1 5 Process Step 2 8 Process Step 3 4 Process Step 4 3 The time required to move each batch between steps is 4 minutes. In addition, the time to move raw materials to Process Step 1 is also 4 minutes, and the time to move completed units from Process Step 4 to finished goods inventory is 6 minutes. The new lean layout will allow the company to reduce the batch sizes from 45 units to 3 units. The time required to move each batch between steps and the inventory locations will be reduced to 2 minutes. The processing time in each step will stay the same. Determine the value-added, non-value-added, and total lead times, and the value-added ratio under the: present and proposed production…
