In this paper, a novel attempt is made to formulate a hybrid system by combining the Fuzzy Cognitive Map (FCM), the Delphi Method, and the VIKOR method through the Haar ranking of Hexagonal Fuzzy Number. To illustrate this technique, the solid waste management is taken. Solid Waste arises from human and animal activities can generate adverse effect on human health and affect the living environment drastically when proper solid waste management is not done efficiently. The proper disposal of solid waste management aids to diminish the horrible impacts on both human health and environment to sustain economic growth and better quality of life. Therefore, this present study analyses the Solid Waste Management through the novel Haar Hexagonal VIKOR with FCM techniques. © BEIESP.
