Title:
RELIABILITY APPROXIMATION CALCULATION METHOD FOR LARGE-SCALE MULTI-STATE SYSTEM HAVING CASCADING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/134258
Kind Code:
A1
Abstract:
Disclosed is a reliability approximation calculation method for a large-scale multi-state system having a cascading structure. In a multi-state system having a cascading structure, connection structures between any parent node and all child nodes pertaining to the given parent node are divided into four types, and then different techniques are used for processing the four types. The four types are used to sequentially calculate state probability distributions of parent nodes at each layer of a complete tree structure starting from leaf nodes at the ends of the structure and moving upwards one by one, so as to finally obtain, according to the parent nodes, the state probability distribution of the entire multi-state system having a cascading structure, thereby obtaining the reliability of the multi-state system having a cascading structure. The present invention achieves reliability approximation calculation for a large-scale multi-state system having a cascading structure, and realizes a balance between calculation accuracy and computational efficiency. Computational complexity is upgraded from exponential complexity of an original exact calculation to binomial complexity, such that calculation speed is greatly improved.
