Assignment:
1. Dairy Queen restaurant in a small West Texas town is being studied using simulation modeling where the objective of the study is to investigate limitations in throughput (number of customers served per time period. For this modeling exercise give:
a. Components
b. Parameters
c. Variables
d. Relationship
2. If we had some other objective instead of throughput (something related to electrical power used, for example), would you expect Why or why not?
3. A production line has two stations in series with the following features: Every 10 minutes a new unit arrives for assembly; station 1 has 1 operator who minutes uniformly distributed. Station 2 has 2 operators who work in parallel (a unit has to go through only 1 of the 2 operators. Processing times are normally distributed with mean 1 minutes and standard deviation 4 minutes. Give the Arena model.
4. For the system in problem 3 compute theoretical utilization of the two stations
5. Iif we want to compute total time in system (time elapsing beginning with entry into the system and ending with completion at the second station, show the additional Arena modules necessary to have each entity having its time in system computed.
6. When we use a single Process Module that is a Seize Delay Release to model two servers in parallel (an arriving entity is served by only one of the two about the two servers and the entire process of serving arriving entities. State what these assumptions are (at least two).
7. What is the significance of the Base Time Units in the Arena Setup menu? (The default is Hours.)
8. In a Create module we might have time between entries to be NORM(30,20) minutes. What might be troublesome about this time between creations?
9. Give an example that might be found in a real system where we would use in the Create module something different from the default of 1 entity per arrival.
