1. Consider a 4-step process with all the steps in a series. Each step takes 6 min/unit. If the processing time of the first step is reduced to 5 min/unit, the minimum flow time of the process will not reduce.
True
False
2. A process has three steps. There is one worker at each step. The time taken at step 1 is 4 minutes, at step 2 is 6 minutes and at step 3 is 10 minutes. Steps 1 and 2 are sub-assemblies that are done in parallel, and feed to the assembly step 3. The minimum flow time of the process is:
a. 11 minutes
b. 13 minutes
c. 16 minutes
d. 19 minutes
3. Capacity utilization and labor utilization of a process are always equal.
True
False
4. A process has three steps. There is one worker at each step. The time taken at step 1 is 4 minutes, at step 2 is 6 minutes and at step 3 is 10 minutes. If one more worker is added at step 3, the capacity of the process before and after adding these workers is
a. 6 units/hour; 12 units/hr
b. 4 units/hour; 8 units/hr
c. 6 units/hr; 10 units/hr
d. 4 units/hour; 6 units/hr
