摘要
软件可靠性工程中的软件可靠性分配是一项重要的设计技术,软件可靠性优化分配方法应用的研究对软件可靠性影响十分关键。以某型导弹发射系统控制软件的功能特点为基础,建立了基于层次分析和频率比的软件可靠性优化分配模型。该模型首先运用层次分析法定量确定软件各部分的相对重要性,然后将得到指标再应用于基于频率比的软件可靠性分配模型,获得各组件的可靠性指标。通过算例计算表明,采用该种算法,由于综合权衡了用户方、程序开发方的观点,使得可靠性分配指标具有较好的可用性。
The software reliability engineering of software reliability allocation is an important design technology, so study of the software reliability allocation method is critical. Considering the function characteristics of launching system controlled-software, software the analytic hierarchy process and frequency ratio. By u reliability allocation model is presented based on tilizing analytic hierarchy process to quantitatively determine the relative weight value for each software component first, and then by applying the obtained datum to the frequency ratio models, the reliability index of each component is obtained by solving the model. Lastly, the reasonable and validity of this method of the launching system controlled-software is proved by integrating consumer and programmer.
