4Conceptual Modelling (Explanatory Model)
Introduction
As stated in chapter 1, DES takes a systems approach to create an explanatory model consisting of individual processes and their interdependencies. The explanatory model will provide a structural representation of the system. This structure enables a variety of future behaviours and provides a representative that helps explain the simulation model results. In general, pure explanatory models are seldom found, and in a DES model, we usually depend on descriptive sub-models (chapter 5) to describe individual relationships and variability. For conceptual modelling, in regard to the explanatory model, the emphasis should be on representing those processes which ...
