1. If the minimum flow time increases, the cycle time would also increase.

True

False

2. A product requires two steps, A and B. Step A is the predecessor of Step B. Two workers are assigned to A, and one worker is assigned to B. For each product, the process time in Step A if the work is done by one worker is 20 min. The process time in Step B if the work is done by one worker is 15 min. Each worker works for 480 minutes/day. Suppose the process is producing at 25 units/day. What is the labor utilization?

a. 50%-79%

b. 80%-100%

c. 20%-49%

d. <10%

3. 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 capacity of the process is

a. 12 units/hour

b. 6 units/hour

c. (12+10+7.5)/3= 9.83 units/ hour

d. 10 units/hour

4. 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 cycle time of the process will not reduce.
