1. Simulation Problems
Jason R. W. Merrick

2. Problem 1 Implement Exercise 3.1
Use an attribute that specifies which plating processes is to be performed first: front or rear.
Use Decide modules to route the entities through the system

3. Problem 2 a) Open Model 03-01.doe in the Arena Book directory
Add a second machine to which all parts go immediately after exiting the first machine
Processing times are the same as the first machine
Examine the effect on the results for 1 week of simulation

4. Problem 2 b) After the second machine there is a pass/fail inspection
The inspection take 5 minutes every time
There is an 80% chance of passing
Failed entities must go back through the second machine and be re-inspected
Entities may pass through the process-inspection route as many times as needed.

5. Problem 2 c) Entities can now either pass, fail or be sent for re-work
Assume a 80% passing rate, 9% failure rate and a 11% re-work rate
Failed items must exit the system and be counted
Examine the effect on the results for 1 week of simulation

6. Problem 2 d) Entities cannot be re-worked more than once
Ensure that entities that have gone through re-work can either pass (80%) or fail (20%)
