某型高炮自动机故障树模块化分解与结构重要度研究

某型高炮自动机系统是单调关联系统，由于自身结构的复杂性，故障树分析（FTA）的最小割集数量众多，为了有针对性地研究重要底事件，提高故障树分析的效率，采用深度优化最左遍历的方式搜索故障树，将故障树分为若干子模块，运用结构重要度分析方法确定子模块的重要度次序，为测试研究自动机关重件提供了依据。

Research on Modular Decomposition and Structure Importance of FTA of Automaton of Anti-aircraft Gun

The anti-aircraft gun automaton system is coherent system, because of the complexity of its structure, there are enormous minimal cut sets during it＇s fault tree analysis （FTA） process. In order to research important bottom events and imprve the efficiency of FTA, the depth first left most （DFLM） traverse method was introduced to search fault trees and divide them into some sub-modules, then the order sub-modules using structure importance method was determined. A- nalysis results provided testing advices for experimental studies of automaton.
