Two-workstation line with variation

Work Station 1 Processing time = U(0.5,1.5)

Work Station 2 Processing time = U(0.5,1.5)

Now suppose the processing time for each workstation averages one minute, but varies along a uniform distribution ranging from 0.5 to 1.5 minutes (represented by U(0.5,1.5)).

Q4. Qualitatively, how do you expect your answers to the three previous questions to change for this process?

See the below table workstations with Random Variations & no buffers & watch closely to illustrate how the process changes for this uniform distribution. Then answer question

Workstation A Task Time: 1.00 +-0.50 Time Unit: Mins Utilization: 87%

Work Station B Task Time: 1.00 +-0.50 Time Unit: Mins Utilization: 85%

Process Metrics Avg. Throughput Time (Min) = 2.16 Cycle Time = 1.16 Output Rate per Hour = 51.52 Utilization = 86.02%

Q5. Why do the operating performance measures have the effect noted in Question 4?
