The development of toolkit of cognitive modelling for research of difficult systems
In the article the approach to modelling and the analysis of functioning of difficult systems based on indistinct cognitive maps is described. The theoretical part of the article is devoted description of modern family cognitive maps, the short characteristic and the analysis of following groups is given: Cognitive Maps, Fuzzy Cognitive Maps, Fuzzy Cognitive Maps by Silov, Rules Based Fuzzy Cognitive Maps, Generalized Rules Based Fuzzy Cognitive Maps, Relational Fuzzy Cognitive Maps, Neutrosophic Relational Maps, Dynamic cognitive networks. The concept of fuzzy way is entered for the development of mathematical toolkit and the model of fuzzy pulse process is offered. The practical component of the article is directed on the description of examples of the decision of separate problems of cognitive modelling with application of the device fuzzy directed graph of the 1st kind. The offered approach will allow to develop forecast scenarios of development of difficult system taking into account its reaction on external influences.
