CURIA, Lisandro e LAVALLE, Andrea. Decision strategies in dynamic systems using fuzzy cognitive maps: Application to a socio - economic example. JISTEM J.Inf.Syst. Technol. Manag. [online]. 2011, vol.8, n.3, pp. 663-680. ISSN 1807-1775. http://dx.doi.org/10.4301/S1807-17752011000300008.
Situations in which human beings develop their daily tasks are extremely complex and dynamic. In each field, the analysis of the system's variables under consideration can be simplified if the system is conceived as a set of concepts, where a change in each of them will cause changes in the remainder. In the analysis of a particular problem, the representation of concepts in the form of a map helps to synthesize information detecting the main concepts that are linked to the problem. In these cases, Fuzzy Cognitive Maps (FCM) are able to synthesize much of this information. Also with this technique is possible to follow the evolution of the concepts to a state of equilibrium and therefore allow us to study the dynamics that takes the passage from one state to another given the situation under review. This paper describes the construction and analysis of the Fuzzy Cognitive Maps technique through an economy application example. The aim is to present a methodology supported by the FCM to analyze the evolution and impact on the system causing by the change in the value of one or more concepts involved.
