Various processes and techniques are used to assure the model matches specifications and assumptions with respect to the model concept.
The objective of model verification is to ensure that the implementation of the model is correct.
Due to that, a model should be verified and validated to the degree needed for the models intended purpose or application.
In the context of computer simulation, verification of a model is the process of confirming that it is correctly implemented with respect to the conceptual model (it matches specifications and assumptions deemed acceptable for the given purpose of application).
"Simulation models are increasingly being used to solve problems and to aid in decision-making.
