Three simulation approaches have been proposed or employed to study the behavior of

causal maps:

1. Nozcika, Bonham and Shapiro (1976) have proposed an approach to the computer

simulation of individual belief systems.

2. As noted in Chapter I, the affinity of causal maps to system dynamics modeling has

prompted some to advocate influence diagrams as a way to analyze the behavior

of causal maps.

3. A third approach is based on fuzzy logic and the use of neural networks. Fuzzy logic

has been advocated and demonstrated in many IS designs, whereas the possibility

of linking fuzzy logic to neural networks has been demonstrated but not widely

adopted in the literature.

We will briefly sketch the main ideas in each approach.
