Question 2 15 Points A system is composed from two stations in series. Parts arrive to the system exactly every 55 minutes from the warehouse. Parts then arrive to station 1, this station has two workers (capacity 2) processing times is expo(8.2) minutes. The workers have a break after 4 hours of the shift for a duration of 1 hour. The workers do not take the break together (staggered) use wait policy. After that the parts arrive to an automatic machine, the machine has a processing time of unif(4.8.5.2) minutes. However this machine suffers from two failure modes the 1st has a up-time of expo(5) hrs and down-time of expo(20) minutes. The second failure mode has an up-time of UNIR10,50) hours and a downtime of exactly 1 hr (use preempt rule for all failure modes). Run the system for 20 days, 8 hours per day. Do 10 replications and select the correct answers only: A The percentage of time the automatic machine is in the failed state is about 21% of the simulation time B The total time in parts spend in the system is more than or equal to 200 minutes. The parts waiting time for station 2 is higher than station 1 The maximum WIP in the system (in the 10 runs) is 135 parts The parts waiting time for station 1 is higher than station 2 The average WIP in the system is about 24.7 parts The total time in parts spend in the system is less than 200 minutes. H) The percentage of time the automatic machine is in the failed state is about 8.7% of the simulation time
