Timing on when to use simulation
When is Simulation an Appropriate tool ?
Simulation may be used for playing with new concepts or prior policies where to incorporate, to plan for what will occur.
One can use simulation to validate analytical solutions which can be used to predict impact of the system that behaves in a particular environment
Models of simulation developed for training allow to learn at no cost and perturbing on-the-job learning.
study and experimentation with the internal
interactions of a complex system
Knowledge gained in the design of a simulation model may be of great benefit to suggest changes in the investigated system
When is Simulation is not an Appropriate tool to use
The first rule notes that simulation should not be used where common sense can solve the problem.
Second rule says simulation should not be used when the issue occurs can be analytically solved.
easier to
perform direct experiments
costs of conducting a simulation exceed the savings of conducting a prototyping of the specific experiment
Where time and resources in conducting a simulation is unavailable
Where data is unavailable
The ability to verify and validate the model where time is insufficient and lack of experience personnel
System behavior is too complex or cant be defined such as Human Behavior
