Develop an understanding of the problem situation
Determine the modeling objectives
Design the conceptual model: inputs, outputs and model content
Collect and analyze the data required to develop the model
General objectives: Flexibility, Run-speed, Visual display, and Ease-of-use.
Model Scope: Table with Entities, Activities, Queues, and Resources
IID (Independent and Identically Distributed)
PRN is not random, but behaves as random numbers
Seed (starting value of random number generator)
Identical seed makes identical Random Number Streams
Repetition of random numbers in a Random Number Stream
A majority of the random numbers are identical. Random number seeds may be two consecutive random numbers in the stream.
An algorithm where a previous random number is used to calculate the next number.
This is data that are sampled from the same underlying distribution and independent from each other. Usually, output data from different replications must be IID to use simple statistical tools.
