Multiobjective fuzzy and stochastic engineering optimization with maximizing reliability

This paper introduces a design methodology using fuzzy theory to find random design variables by maximizing the reliability as well as optimizing multiobjectives. The formulation of the problem involves random parameters and probabilistic and fuzzy probabilistic constraints. The objective weighting strategy in the multiobjective fuzzy formulation is presented. An engineering design example illustrates this optimization process and the solution techniques.
