Reduce Setup Time Vernon Inc. has analyzed the setup time on its computer-controlled lathe. The setup requires changing the type of fixture that holds a part. The average setup time has been 140 minutes, consisting of the following steps: a. A company plans to setup a machine to increase the productivity. The average setup time is 140 minutes. Do you think the management needs to minimize the setup time. Identify the reason that supports the answer. a. Yes b. No a. The setup time is not a concern of the company as it is not related to productivity of the company. b. The setup time should be considered because long setup time leads to increased economic cosi of the setup. c. The cost incurred for setup can be ignored as it is related to machinery. d. Long setup cost can be recovered as depreciation. b. A company plans to setup a machine to increase the productivity. The average setup time is 140 minutes. The company wishes to control the setup time. Identify the statement that suits the given situation. a. Identify the wait time and non-value-added time and eliminate that with effective planning so that the setup time can be reduced. b. Identify the machine that has less setup time. c. Identify the laborers are contributing less to the setup process and eliminate them from the process. d. None of the above. Isaacson Dental Inc. is considering a new lean product cell. The present manufacturing approach produces a product in four separate steps. The production batch sizes are 50 units. The process time for each step is as follows: The time required to move each batch between steps is 6 minutes. In addition, the time to move raw materials to Process Step 1 is also 6 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 50 units to 2 units. The time required to move each batch between steps and the inventory locations will be reduced to 1 minute. 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 (a) present and (b) proposed production approaches. If required, round percentages to one decimal place. time for each step is as follows: The time required to move each batch between steps is 6 minutes.
