TLDR
An effort towards the improvement of FCMs response is made, implementing for first time a new equation for the calculation of concept values and replacing the sigmoid function with Anti Windup control method.Abstract:
Effective decision making is the fundamental factor for the appropriate operation of any system. Several methods have been developed in recent years, and Fuzzy Cognitive Maps (FCMs) is one of them. Basics of FCMs are briefly presented. They have been used in a variety of applications with a very good degree of success. All these years some of their drawbacks have been detected and discussed by several researchers, who are searching for ways to improve FCMs performance and broaden their implementation area. An effort towards the improvement of FCMs response is made, implementing for first time a new equation for the calculation of concept values and replacing the sigmoid function with Anti Windup control method. Results are presented and discussed, and further thoughts leading towards new research directions are presented.read more
