Abstract

The invention relates to a system reliability block diagram computer automatic identification and rapid calculation method. The method comprises the following steps: inserting a parallel relationshipnode between a parallel component and a common import component in a system reliability block diagram, respectively setting a union-union central component and a voting component as a union-union relationship node and a voting relationship node, and setting other components in the system reliability block diagram as component nodes; generating a system reliability network according to the connection relationship between the nodes, and obtaining an output reliability value of the system reliability network according to a preset calculation rule, wherein the output reliability value is a reliability value of the system reliability block diagram. By using the method, the corresponding system reliability network can be generated; the whole process is simple and can be completely and automatically realized by a computer, the defects that the manual calculation efficiency is low and the method is not suitable for a complex system are avoided, and the problem that the Monte Carlo simulation method cannot accurately calculate the reliability value of the system is also solved.

Description

technical field [0001] The present application relates to the technical field of system reliability evaluation, in particular to a computer automatic identification and fast calculation method of a system reliability block diagram. Background technique [0002] Reliability refers to the ability of a product to complete specified functions under specified conditions and within a specified time, and reliability is a probability measure of reliability. The reliability block diagram is a logical diagram for studying the relationship between the system and components from the perspective of reliability, and it is a common tool for system reliability modeling and calculation. Common connections in reliability block diagrams include series connection, parallel connection, voting, and connection, etc. [0003] According to the reliability block diagram, the reliability value of the system can be calculated. The main degree calculation methods include manual method, Monte Carlo simu...
