中文摘要：

提出一种安全监测系统传感器逻辑结构的动态优化方法，通过一个动态贝叶斯网络描述被监测系统（设备）与安全监测系统的关系，使由于安全监测系统“漏报”和“虚警”两类故障引起的总预期损失降到最小，从而确定传感器系统最优的动态逻辑结构。用一个三传感器安全监测系统逻辑结构动态优化的算例说明所提方法的特性和优点。

英文摘要：

A dynamic optimization method to determine the optimal dynamic sensor logic structure （or decision criteria） of safety monitoring system is proposed, which models the entire system behavior composed of the system （ or equipment） and its safety monitoring system using dynamic Bayesian networks （ DBN）, minimizes the total expected loss caused by two types of the safety monitoring system failure： a failed-dangerous （FD） failure and a failed-safe （FS） failure. An illustrative example of a three-sensor system shows the characteristies and merits of the proposed method.
