Part A.
This is a variation of the Lab 8 assignment. Refer to the figure below.
In the earlier assignment, the processing times at the stations were the same regardless of the part type.
Here, the processing times depend on the part type as shown in table 1 below.

Part Type 1 (25%)
Station A (Pert(2,5,8))
Station C (Pert(2,6,11))
Part Type 2 (35%)
Station A (Pert(1,3,4))
Station B (Uniform(5,11))
Station C (Uniform(2,11))
Part Type 3 (15%)
Station A (Triangular(2,5,8))
Station B (Triangular(5,9,11))
Part Type 4 (25%)
Station B (Pert(5,9,11))
Station C (Triangular(2,6,11))
In the previous assignment, parts arrived from four separate sources with their own arrival process. In this assignment, there is only one arrival stream where parts arrive at an average of once every 10 minutes. There are four different part types based on the percentages specified in table 1. Use the same replication length as in the previous assignment (40 hours).
1.
How long is each part type in the system? _________ , __________ , __________ , __________
2.
What is the utilization of each of the servers? ________ , _________ , __________
3.
What is the overall time for all part types in the system? __________
4.
What is the utilization of the cart? __________
Name: __________________
UIN: ___________
Define your own state variable and tally statistic variable to determine the average overall time spent by
the parts in the system.
5.
What is the tally statistic value for the 40 hour run? __________
Determine the 95% confidence interval of the average amount of overall time spent by the parts in the system using your tally statistic variable. Create a scenario within your experiment that runs the model for 8 hours per day and runs for 10 days (replications). 6.
Point estimate: _________ ; Confidence Interval: [ , ]
Save Part A model and results. Make a copy for Part B.
Part B.
Develop a general Simio model to handle more than the four part types that we have used so far.
We will use Relational Data Tables (database concept) to facilitate the modeling of relationships. See figure below.
1.
What is the utilization of each of the servers? ________ , _________ , __________
2.
What is the overall time for all part types in the system? __________
3.
What is the utilization of the cart? __________
4.
Is there anything different in this model as compared to part A? (open ended question) ______________________________________________________________________________
