gregorbj/FSDM: Fuzzy Systems Dynamics Model

This package implements the Fuzzy Systems Dynamics Model which is similar to fuzzy cognitive maps (FCM) in representing a model of causal effects as a digraph but uses different mathematical and algorithmic approach to calculating the effects of the change in one concept on the change in another. Whereas the in the FCM approach the states of concepts are related to one another, in the FSDM approach the changes in the states of concepts are related to one another. The changes in state are a function of edge weights in the digraph which identify the causal strength and the respective values of the anterior and posterior concepts in the relationship. Because change in the model is a function of both the value of concepts and their changes, approach is somewhat similar to the systems dynamics model approach but with a simpler representation of dynamic relationships.
