A further study on model evaluation to assist policy analysts and decisionmakers in shaping their policy recommendations is presented.
The basic steps are listed in the modeling process and provides a minimal set of criteria necessary for model evaluation. It is emphasized that good documentation is important to ensure that the model is thoroughly understood, operated, and maintained. The relationship of the main subcategories of validity; i.e., theoretical validity, operational validity, and computer model verification, are discussed. Review and updating are important aspects of maintainability. Some factors that affect a model's usability include availability of data, the understandability of the model's output, the presentation format chosen, the transferability of the model to another computer system, the accessibility of the model, the size of the model, the time of a typical run, and the costs to set up and run the model.
