Description:
The following is meant to be an example of the combination of an Expert System (XPS) and a System Dynamics (SD) model in which the farreaching effects of cash management decisions in a complex of feedback relationships in a company are illustrated.The great advantage in proceeding this way is to use the results of an Expert System as constants and initials in a System Dynamics model. That means, that the user is enabled to study the results of a static Expert System in a dynamic model.The mentioned System Dynamics model is created on the background of an ancillary supplier for the car industry. Rather to simulate the real system in a very detailed way the model reduces this real system to the main areas of the company. As in this paper the point of main emphasis is to demonstrate a possible way of linkage of the two systems a short problem definition is followed by the description of the most important feedback-loops in causal-loop diagrams of the System Dynamic model. Subsequently the outcome of a model simulation with it's graphic and tabular results is to be analysed under the aspect of influence of constants and initials originating from the Expert System concerning cash management decisions.
