摘　　要：软件可靠性分配是软件设计过程中一项重要的质量保证活动。介绍了层次分析法(AHP)的原理及其在指控系统软件可靠性指标分配中的应用过程,包括软件的层次结构模型的建立,系统中各层软件元素相对权值的确定,各软件模块相对于软件实用性的组合权重的确定以及获取软件实用性最大化的可靠性分配模型(基于成本约束)的建立。还讨论了应用信赖度算法求解可靠性分配非线性方程组,从而求得各软件模块的可靠性分配值的方法。The software reliability allocation is one of the most important quality assurance activities in the design process of software. The principle of the Analytical Hierarchy Process（AHP） is mainly introduced and the application of the AHP in the reliability allocation of the software in command control system is described： firstly,a hierarchical structure model of the software system is builded.Secondly, combined weights of every software module to the utility of software system are calculated and then the reliability allocation model for best utility is established within the cost limits. And how to solve the nonlinear equations of reliability using trust region algrithm is also discussed.
