Soft modeling of knowledge systems through fuzzy Petri nets

Abstract

Knowledge in the social and human Sciences cannot be modeled with old time mathematical modeling techniques. In this situation, it would be very useful to have modeling approaches capable to express the richness of social reality, including its vagueness and uncertainty. Aiming at this objective, a soft modeling approach is proposed, implemented as a generalized fuzzy Petri net. This model can be then used to make inferences and to solve problems related to the complex system. © 2005 by International Federation for Information Processing.
