Truss design optimization using fuzzy geometric programming in parametric form

Abstract

The main goal of the structural optimization is to minimize the weight of structures while satisfying all design requirements imposed by design codes. A truss design model in fuzzy environment has been developed. The present paper proposes a fuzzy geometric programming approach in parametric form .We have considered a single objective structural optimization problem with weight as an objective function. The structural related load and other parameters are taken as fuzzy in nature. This structural model is formulated as a fuzzy geometric programming problem in parametric form. Fuzzy geometric programming in parametric approach is used to solve this single objective structural optimization model. Numerical example is given to illustrate the model through this approximation method. This approach provides an alternative solution technique to this problem. This method is more reliable and acceptable.
