Keyword:  复杂系统连锁性故障博弈论协同学序参量;
Abstract: 针对故障树法和贝叶斯网络方法存在的复杂系统连锁故障非动态性分析的问题,结合博弈论和协同学中序参量的概念提出一种连锁故障预测方法.在系统众多状态参量中,序参量主宰着系统演化的方向.每个序参量都企图主宰系统的格局,这一过程恰恰体现了参与人之间的博弈行为.将子系统中的多个序参量映射为博弈中的参与人,在得益函数的定义中,还考虑到序参量之间除了竞争外也有合作,建立了一种基于协同学的非合作博弈模型.以火灾报警控制网络为应用实例,仿真结果表明接近临界阈值的序参量会导致故障子系统与其他子系统的关联作用增强,为复杂系统连锁性故障预防提供了新的途径.
