“…They have provided many possible solutions, and we will discuss a few of them in the following sections. Similarly, Roychowdhury and Wang 21 have attempted to understand the problem of defuzzification from the scope of optimal selection of an element from a fuzzy set. They have used the concepts of interaction, variability, and voting techniques to compute an optimal solution.…”

Defuzzification is an important operation in the theory of fuzzy sets. It transforms a fuzzy set information into a numeric data information. This operation along with the operation of fuzzification is critical to the design of fuzzy systems as both of these operations provide nexus between the fuzzy set domain and the real-valued scalar domain. We need the synergy of both of these domains to solve many of our ill-posed problems effectively. In this paper, we address the problem of defuzzification, we present merits and demerits of various defuzzification strategies that are used in the theory and practice, and in design and implementation of applications involving fuzzy theory, fuzzy control, and fuzzy rule base, and fuzzy inference-based systems. We also present in this paper a simple and yet a novel defuzzification mechanism. ᮊ

“…21, Roychowdhury and Wang attempted to explain the concept of defuzzification using the ideas of evolutionary biology. In evolutionary biology, the ecology is functionally dependent on the interaction of the different species, and is guided by the principle of natural selection.…”

“…One of them, pursued by Roychowdhury and Wang (1996) and Roychowdhury et al (1999) is based on exploring the interaction between the chosen element and its neighbors in a way inspired by evolutionary biology. The authors show that the method is suitable for adaptation to search for optimal value.…”

“…The robust strongly satisficing set can now be defined by restricting the robust satisficing set to the region of support defined by the robust equilibrium set . The robust satisficing set can be expressed as (13) otherwise (14) from which we see that (7) and (8) are special cases with a singleton and a delta function placing all belief mass on the single value . We now have a general definition for a robust strongly satisficing control.…”
