本文提出了一种从过程系统的框图表示中获取系统可靠性和可用性参数的统一方法。它从获得系统中最小路径的计算机算法开始，然后展示了如何将这些信息与单元可靠性数据相结合来获得整体系统可靠性，以及系统可靠性对单元可靠性(灵敏度)变化的响应。然后演示如何利用这些敏感度通过设备冗余来优化系统可靠性和可用性。该方法被扩展到自动生成系统故障树，以及故障树和框图之间的数学关系。
This paper presents a unified approach for obtaining system reliability and availability parameters from block diagram representations of process systems. It starts with computer algorithms for obtaining the minimal paths in a system, then shows how this information can be combined with unit reliability data to obtain the overall system reliability, and the response of system reliability to changes in unit reliability (sensitivities). It then demonstrates how these sensitivities can be used to optimize the system reliability and availability by equipment redundancy. Extension of the methodology to the automated production of system fault trees as well as the mathematical relationship between fault trees and block diagrams are noted.
