Parts arrive at a four-machine system according to an exponential interarrival distribution with mean 10 minutes. The four machines are all different, and there’s just one of each. There are five part types with the arrival percentages and process plans given here. The entries for the process times are the parameters for a triangular distribution (in minutes).
Part Type % Machine/ Process Time Machine/ Process Time Machine/ Process Time Machine/ Process Time
1 12 1) 10.5,11.9,13.2 2) 7.1,8.5,9.8 3) 6.7,8.8,10.1 4) 6.8.9.10.3
2 14 1) 7.3,8.6,10.1 3) 5.4,7.2,11.3 2) 9.6,11.4,15.3

4 24 3) 7.9,9.4,10.9 4) 7.6,8.9,10.3 3) 6.5,8.3,9.7 2) 6.7.7.8,9.4
5 19 2) 5.6,7.1,8.8 1) 8.1,9.4,11.7 4) 9.2,10.7,12.8
The transfer time between arrival and the first machine, between all machines, and between the last machine and the system exit follows a triangular distribution with parameters 8, 10, 12 (minutes). Model the system using ARENA syntax and explain the modules why you used with the data supplied.
