Question: The interarrival time for parts needing processing is given as follows:

Interarrival Time (Seconds)            Proportion

           10-20                                0.20

           20-30                                0.30

           30-40                                0.50

There are three types of parts: A, B, and C. The proportion of each part, and the mean and standard deviation of the normally distributed processing times are as follows:

Part Type            Proportion             Mean              Standard Deviation

A                           0.5              30 seconds                3 seconds

B                           0.5              40 seconds                4 seconds                         

C                           0.5              50 seconds                7 seconds

Each machine processes any type of part, one part at a time. Use simulation to compare one with two with three machines working in parallel. What criteria would be appropriate for such a comparison?
