Title:
POLYMORPHIC DECISION DIAGRAM-BASED METHOD FOR ANALYZING AND CALCULATING RELIABILITY OF SYSTEM COMPRISING STANDBY
Document Type and Number:
WIPO Patent Application WO/2018/227673
Kind Code:
A1
Abstract:
Disclosed in the present invention is a polymorphic decision diagram-based method for analyzing and calculating reliability of a system comprising standby. A polymorphic system model comprising standby mode components is built; and a polymorphic decision diagram is established according to the state transfer possibility of each component in a system. By means of the building, simplification and decomposition of the polymorphic decision diagram of the system, the occurrence probability of each path in sub-diagrams of the polymorphic decision diagram of the system is obtained by utilizing integral operation, and the occurrence probability of each path in the polymorphic decision diagram is calculated by considering failure probability during startup of standby components, so that the system reliability is calculated. With the method according to the present invention, a polymorphic system comprising standby is used as an object, and polymorphic components comprising standby whose state transfer complies with any distribution may be processed in a programmed manner, so that accuracy is high and the calculation speed is fast; and the method is of important significance for reliability theoretical analysis of the polymorphic standby system whose state transfer complies with any distribution as well as the engineering application thereof.
