摘　　要：为保证复杂系统的安全生产,提出了基于网络流的复杂系统安全最优配置方法。结合实际系统特点建立了一系列基于网络流的形式化模型。利用网络割处理方法分析网络流的流量变化规律,定义了形成系统网络最优可行流必需的约束函数;构造了最大安全性与网络流的关系函数;给出了求解各种状态调节量的求解公式。使用标号算法对实际系统进行状态调节。最后通过一个例子说明了上述方法的实现过程,并表明该方法能够有效地稳定系统的状态,并能达到保障系统安全的目的。To guarantee the production safety of complex systems,a network flow based optimal allocation was presented.A series of formal models were set up based on practical system characteristics.Network flows change law was analyzed by utilizing the network cut and models,and the constraint function to construct optimal feasible flows was defined.The relationship functions of maximal safety and network flow were established,and solution formulae for all adjusting quantities were presented.The labeling algorithm was used to adjust status of actual systems.Finally,an example was used to demonstrate the implementation process of the proposed method.It revealed that the proposed method could effectively stabilize system status and satisfy the system safety requirements.
