Fuzzy congnitive map
Definition
A Fuzzy Cognitive Map (FCM) is a semi-quantitative modeling methodology used to represent and analyze complex systems through causal relationships between concepts. It consists of a directed graph in which nodes represent system variables or concepts, and weighted links express the strength and direction (positive or negative) of causal influence, using fuzzy logic. FCMs are used to integrate expert knowledge, explore system behavior, simulate scenarios, and support decision-making in situations characterized by uncertainty, incomplete data, and multiple interacting factors.
