Development of Reliability and Safety Analysis Support System for Man-Machine Systems

在分析系统可靠性和安全性时，重要的是不仅要考虑系统硬件，而且还要考虑与系统相关的人员。本研究的目的是构建一个人机系统可靠性与安全性分析支持系统。取得的主要研究成果如下：1.对人机系统的人因失误分析评价方法和可靠性安全分析支持系统的研究现状进行了综述。提出并发展了基于简单和有色Petri网思想和技术的人机系统可靠性与安全性建模与定性定量分析方法，并在PC机上实现了人机系统可靠性与安全性分析支持系统的原型系统。建立了监控组态下大型复杂系统报警时应采用的安全管理方案的概率分析和概率模型。并以某泵站的控制和运行为例，对所开发的可靠性安全分析支持系统的可行性和适用性进行了研究。

In the analysis of system reliability and safety, it is important to include not only system hardware but also men who are with the system. The objective of this research is to construct a reliability and safety analysis support system for man-machine systems. The main research results obtained are as follows :1. Research surveys are conducted on the state of arts of the human error analysis and evaluation methodology and the reliability and safety analysis support system for man-machine systems.2. Modelling and qualitative and quantitative analysis methods of reliability and safety for man-machine systems are proposed and developed by use of both simple and colored petri-net ideas and techniques, and then a prototype system of reliability and safety analysis support system for man-machine systems is installed on a personal computer.3. A probabilistic analysis and probabilistic models are developed of safety management schemes that should be used upon an alarm in a large-complex system under supervisory control configuration.4. Feasibility and applicability study of the developed reliability and safety analysis support system is made especially on the control and operation of a pumping station.
