基于子系统综合因子的软件可靠性分配方法

针对拥有多个分配在不同配置硬件环境上的软件子系统的综合软件系统，介绍了一种基于各子系统综合因子的软件可靠性分配方法。综合因子的确定涉及到子系统利用率等诸多因素，它的数值可以是软件详细规划时计算给出，从而对整个系统进行可靠性预分配，也可以在实际开发扣测试进程中动态地确定，从而不断地重新修正分配数值。给出详细的实例运算过程，并与传统方法进行了比较。

A Method of Software Reliability Allocation Based on Subsystem Integrative Factor of Software Subsystem

In order to deal with a software system including several subsystems which hold on different hardware configuration items,a method based on the integrative factor of each subsystem is raised.The calculation of the integrative factor involves several important parts of each subsystem,and it can be given by the system's specification so as to use to do pre-llocation.Also it can be changed with the development of the software system and adjust the allocation values.A detailed instance has been given to describe this method and the result is also compared with the original allocation results.
