    Hi Riza and all,

    John L. Casti's book (Would-be worlds) has a number of
    tips on how to understand models in general; I found
    that adapting some of his ideas I could "feel" better
    if my models were more or less correct.

    Depending on your problem, you can also use techniques
    such as the one described in John L. Miller's
    article "Active Nonlinear Tests of Complex Simulation
    Models".

    Remember that ultimately what you may be trying to test
    is the adequability of the model to the world you are
    trying to capture; and most of the time, only an
    experienced person on the subject can answer that.
