... functional as well as physical fitness for ease of upgrade. This paper presents the development of a novel approach and its implementation algorithm for a systematic design of product upgradability. The framework of this approach consists of two major phases––modeling and optimization. Fuzzy logic is used...

... simplex is an effective optimization algorithm. It expands and contracts a simplex based on comparing the function values of the simplex points with the highest and the lowest function values. The decisions to expand and contract the simplex as well as changing its orientation are based on fuzzy logic...

... by incorporating fuzzy logic in optimization algorithms. The proposed ideas are used to develop a new adaptive form of the simplex search algorithm whose objective is to minimize a function of n variables. The new algorithm is labeled Fuzzy Simplex . The search starts by generating a simplex with n + 1 vertices...
