Timed Fuzzy Cognitive Maps

Taking time into consideration in the FCM model and the subsequent numerical calculation is a hot FCM issue. This work investigates an approach for introducing the time in Fuzzy Cognitive Maps (FCM) framework and it proposes the Timed-FCM (T-FCM) that incorporates time steps in their structure and constitutes an extension of FCMs. The proposed T-FCMs take into consideration the time evolution and the fact that the parameters of any system change with the time and it accepts intermediate states and results of the modeled system. In any problem, its factors change differently over time and so their influence as is presented on the interconnections between the concepts are time dependent.
