Consider the following continuously operating job
shop. Inter-arrival times of jobs are distributed as
follows:
• Processing times for jobs are normally distributed,
with mean 50 minutes and standard deviation 8
minutes.
• Construct a simulation table and perform a
simulation for 100 new customers.
Time Between Arrivals (Hours) Probability
0 0.23
1 0.37
2 0.30
3 0.10
• Assume that, when the simulation begins, there is
one job being processed (scheduled to be completed
in 25 minutes) and there is one job with a 50-minute
processing time in the queue.
• Using a spreadsheet estimates:
1. What was the average time in the queue for the
100 new jobs?
2. What was the average processing time of the 100
new jobs?
3. What was the maximum time in the system for
the 100 new jobs?
