舰载指控系统的软件故障树分析

在现代舰载指控系统的设计中软件所占比例日益增加,软件故障对系统可靠性的影响也更突出,需要对软件故障进行分析。根据现代舰载指控系统的特点,采用软件故障树分析方法,以舰载指控系统的软件系统故障为根节点,从上至下找出导致软件系统故障的所有可能因素,分析其因果逻辑关系,最后建立了现代舰载指控系统的软件故障树。软件故障树以图形演绎的方法直观地反映了现代舰载指控系统的软件故障特性,有助于采取有效措施提高系统的可靠性。

Analysis on Software Fault Tree for Shipborne Command Control System

Software plays a more and more important role in modern shipborne Command Control System, and the influences of software fault on system reliability are more outstanding, it is necessary to analysis software fault. In this paper, a software fault tree analysis method is presented to analysis the software fault. Software system fault of shipborne Command Control System is chosen as the root node, then all possible ingredients which result in software system fault are found from the top down, and the causality between them are analyzed, finally a software fault tree of modern shipborne Command Control System is established. Software fault tree intuitionally reflects software fault characteristic of modern shipborne Command Control System with graphics mode, based on it some methods can be taken to improve system reliability.
