摘　　要：在考虑开发成本约束的基础上,通过建立一种开发成本-可靠度-满意度三者平衡的软件可靠性分配和优化模型,将对软件可靠性最优分配问题转化为对模糊非线性规划问题的求解,从而为软件可靠性分配的最优化问题提供了一种新方法。为获得具有实际意义的数值解,提出一种沿着加权梯度方向进行变异的特殊遗传算法。最后结合实例,证明了该方法的有效性和合理性。A new method of software reliability allocation and optimization was presented.The problem of allocation and optimization of software reliability allocation which was constructed on restricts of software development cost was reduced to the problem of fuzzy nonlinear programming by building a model balancing the relationship of software development cost,reliability degree and satisfaction degree.In order to gain feasible numerical solution to the problem,an improved genetic algorithm which has its mutation in the weighted gradient direction was proposed.By using this method,allocation and optimization of software reliability of can be solved effectively and efficiently.
