Simulation Problems Jason R. W. Merrick
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
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
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. • Examine the effect on the results for 1 week of simulation
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
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%) • Examine the effect on the results for 1 week of simulation
