Abstract

The application relates to a computer automatic identification and fast calculation method of a system reliability block diagram. The method includes: inserting a parallel connection node between the parallel connection components and their common input components in the system reliability block diagram, setting the harmony connection central component and the voting component as the harmony connection connection node and the voting relationship node respectively, and setting the system The other components in the reliability block diagram are component nodes. The system reliability network is generated according to the connection relationship between the nodes, and the output reliability value of the system reliability network is obtained according to the preset calculation rules, and the output reliability value is the reliability value of the system reliability block diagram. Using the above method can generate the corresponding system reliability network, and then obtain the reliability value of the system reliability block diagram. It overcomes the problem that the Monte Carlo simulation method cannot accurately calculate the system reliability value.

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...
