Robert and All:
Here is a set of possibilities:
Validation: the process of comparing the model's output with the behavior
of the phenomenon. In other words: comparing model execution to
reality (physical or otherwise)
Verification: the process of comparing the computer code with the model
to ensure that the code is a correct implementation of the model.
Calibration: the process of parameter estimation for a model. My understanding is
that calibration is a tweaking/tuning of existing parameters and doesn't
involve the introduction of new ones, changing the model structure.
The validation/verification definition is something that Zeigler put out in the 70s
and pretty much matches how the computer simulation community defines these
terms. Calibration seems to be an optimization procedure involved in system
identification or during experimental design.
