Abstract

A fuzzy multi-objective software reliability allocation model was established,and bacteria foraging optimization algorithm based on estimation of distribution was proposed to solve software reliability redundancy allocation problem.As the fuzzy target function,software reliability and cost were regarded as triangular fuzzy members,and bacterial foraging algorithm optimization based on Gauss distribution was applied.Different membership function parameters were set up,and different Pareto optimal solutions could be obtained.The experimental results show that the proposed swarm intelligence algorithm can solve multi-objective software reliability allocation effectively and correctly,Pareto optimal solution can help the decision between software reliability and cost.
