Abstract: For the parameters of product reliability design are uncertain, based on the Liu’s fuzzy chance constrained theory, provides a fuzzy chance constrained programming module of product reliability design that has N sub-systems and several designs can be chosen in every sub-system, on the basis of Liu’s fuzzy simulated based genetic algorithm, improves to check fuzzy simulation for the fuzzy chance constrains. And provides the steps of a fuzzy simulated based genetic algorithm, an instance is given to test that the improvement is reliable, and in search of solution can converge from feasible and unfeasible field, and the searching speed can be improved.

Key words: Chance constrained programming, Genetic algorithm, Reliability
