AI Technical Summary

Technical Problem

Existing technologies are insufficient for effectively analyzing the reliability of reconfigurable multi-stage systems (RMS). Traditional methods face the state space explosion problem and fail to adequately consider the sequential disconnection constraints between stages when dealing with large-scale multi-stage systems.

Method used

By determining the initial set of the system graph model, including the set of connected nodes, the set of unverified connected nodes, and the set of nodes that are not directly connected, connectivity verification and path elimination are performed, transforming the problem into a path search problem of the graph model, and analyzing the reliability of the reconfigurable multi-stage system.

Benefits of technology

It effectively solves the path feasibility problem in RMS reliability analysis, avoids directly traversing all system states, and improves computational efficiency and accuracy.

Abstract

The invention provides a method and device for reliability analysis of a reconfigurable multi-stage system.The method comprises the steps that an initial set of a system diagram model is determined, and the initial set comprises a first node set C, a second node set U and a third node set I, and selecting a first node from the second node set U to perform communication verification with the nodes in the first node set C, updating the second node set U according to a communication verification result, and repeatedly executing until the second node set U is an empty set, thereby generating an effective working path, and analyzing the reliability of the reconfigurable multi-stage system based on the effective working path. According to the embodiment of the invention, the probability enumeration problem in the traditional reliability analysis is converted into the path search problem of the graph model, so that all system states are prevented from being directly traversed. And the path feasibility during reliability calculation is ensured.
