simulation assigment using Arena program

1.
Original model in Assignment 02 is shown to production manager. He pointed out that this is only the first shift of a two-shift day and should be run for 10 days 16 hours per day (10 replications). He suggested the following things based on the results from the previous model:



- On second shift there are two operators at Rework (the bottleneck station) 

-The Sealer fails sometimes

    - Uptimes ~ exponential, mean 120 minutes

    - Repair times ~ exponential, mean 4 minutes

Modify the existing model with the information above and then compare the

results with Assignment 02.doe.
