HW$7/$Sequencing Processes

All parts arrive every ten minutes to a system having three cells $($or workstations$)$ A$,$ B$,$ and C$,$

the first part arrives at time $0,$ subsequent parts arrive at predicted delays $($see below$).$ There are

four part types, each with equal probability of arriving. The process times for the four part types

are given below. The process time parameters are for a triangular distribution $($in minutes$).$

Assume that the transfer time between each station is two minutes. Use the Sequence feature to

direct the parts through the system and to assign the processing times at each station. Use the Sets

feature to collect cycle times $($total times in system$)$ for each of the part types separately. Increase

each of your machine resource capacities to $4.$ Animate your model $($including the part transfers$)$

and run the simulation for $2,400$ minutes.
