Textbook Question
Chapter 16, Problem 1CTE
One approach that can be effective in reducing the impact of production bottlenecks in a job shop or batch operations setting is to use smaller lot sizes.
a. What is the impact of a production bottleneck?
b. Explain how small lot sizes can reduce the impact of bottleneck operations.
c. What are the key trade-offs in using small lot sizes for the purpose of reducing the bottleneck effect?
d. In some cases, the location of a bottleneck will shift (i.e., sometimes it is at workstation 3, another time it is at workstation 12). Furthermore, there can be more than one bottleneck operation at the same time. How would these situations impact

- Ripeka, the warehouse manager at Hine would like to update the company’s inventory locator system so that the picking operation can be streamlined. While conceptually simple to do, she knows that there will be several steps to the update process that will have to be carefully managed.
