B.8 Summary
In this chapter you learned how to analyze data in order to model the input distributions for a simulation model. The input distributions drive the stochastic behavior of the simulation model.
The modeling of the input distributions requires:
Understanding how the system being modeled works. This understanding improves overall model construction in an iterative fashion: model the system, observe some data, model the data, model the system, etc.
Carefully collecting the data using well thought out collection and sampling plans
Analyzing the data using appropriate statistical techniques
Hypothesizing and testing appropriate probability distributions
Incorporating the models in to your simulations
Properly modeling the inputs to the simulation model form a critical foundation to increasing the validity of the simulation model and subsequently, the credibility of the simulation outputs.
