基于群智能的模糊多目标软件可靠性冗余分配

针对软件可靠性冗余分配问题，建立了一种模糊多目标分配模型，并提出了基于分布估计的细菌觅食优化算法求解该模型。将软件可靠性和成本作为模糊目标函数，通过三角形隶属函数对模糊多目标进行处理，用高斯分布对细菌觅食算法进行优化，并将该优化算法用来求解多目标软件可靠性冗余分配问题，设置不同的隶属函数参数可以得到不同的Pareto最优解，实验数据验证了该群智能算法对解决多目标软件可靠性分配的有效性和正确性，Pareto最优解可为在可靠性和成本之间决策提供依据。

Fuzzy multi-objective software reliability redundancy allocation based on swarm intelligence algorithm

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.
