9.  Why do we use verification and validation in simulation?

Verification

  • Verification is concerned with building the model right.
  • It is performed by comparing the conceptual model to the computerized simulation implementation.
  • It tests whether the given model is implemented correctly in the simulation software.

Validation

  • Validation is concerned with building the right model.
  • It is performed by calibration of the model.
  • Calibration is the iterative process of comparing the model to the actual system behaviour.
  • It attempts to confirm that a model represents the real system accurately.


Verification and validation is used in simulation:

  • To produce a model that represents true system behavior closely enough for the model to be used as a substitute for the actual system for the purpose of experimenting with system.
  • To increase an acceptable, level the credibility of the model, so that the model will be used by managers and other decision makers.
