Selection of domotic systems by AHP based rules weights calculation on models of fuzzy rules

Abstract

Many methods exist for performing multi-criteria decision making; one of them is carrying out the decision making based on fuzzy logic. This method is useful when you have qualitative information that is difficult to handle by other methods that work with "crisp" values. This article presents a novel method using AHP (Analytic Hierarchy Process) to determine the weights of the rules that constitute the fuzzy inference model. The advantage provided by this new method is that the weights assigned to the rules are calculated using the AHP methodology, which appart from the values of the weights it gives us a value of the consistency of these weights. We have developed a fuzzy model to calculate weights by AHP and two cases were analyzed for the choice of the appropriate technology for home automation system. The results have been compared with a fuzzy model generated for the same purpose in a previous work and they are similar.
