Choices for the construction of appropriate models

The desires of the user of a modelling system are always moderated by the availability of techniques permitting these desires to be met. To alleviate the difficulties associated with this requires a methodology to guide the user to the best model and simulation technique to meet his needs. A primary requirement in the construction of such a methodology is a comprehensive and understandable classification of the choices inherent in the construction of a model and a categorisation of existing techniques in the light of this classification. This paper has presented such a classification. The modelling process was presented as consisting of three modelling choices involving the definition or adjustment of a number of model properties
