Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the examples.

[0024] The minimum road set algorithm for reliability calculation in the GO method of the two-state system provided by the present invention obtains the reliability of the system by solving the minimum road set of the system, and then calculating the reliability of the system by applying the tolerance-exclusion theorem to all the minimum road sets. The so-called minimum path set refers to the set of minimum basic events necessary to prevent the top event from occurring. Basic method of the present invention is as follows:

[0025] Assuming that all the minimum path sets of the system have been obtained, each minimum path set R i Expressed as a vector [m,n,p...], where m,n,p...represents the minimum road set R i The function operator number contained in .

[0026] Suppose the two-state system has n minimum path sets, which are R 1 , R 2 …R n , the reliability A of the system...

Abstract

The invention belongs to a system reliability analysis technology, and specifically relates to a method for calculating reliability of a GO method in a two-state system. The method comprises the following steps of: solving minimal path sets of the system; and calculating the reliability of the system through an application inclusion-exclusion principle of all the minimal path set. The method is suitable for the reliability calculation in the GO method analysis of the two-state system with multiple shared signals, and is simple in principle and easy to program.

Description

technical field [0001] The invention belongs to the technical field of system reliability analysis, and in particular relates to a reliability calculation method in the GO method of a two-state system. Background technique [0002] GO method is an effective system reliability analysis method. The basic principle of the GO method is to represent the unit by the operator, and the connection between the units by the signal flow, and convert the system diagram into a GO diagram. The quantitative calculation of the GO method starts from the input operator, along the signal flow sequence, and according to the operation rules of the operator, gradually calculates the state probability of the signal flow until it represents the final output signal of the system. The GO method has been developing continuously at the beginning of this century, and gradually has a new algorithm for the quantitative calculation of the GO method; and has the calculation method and transmission rules of ...
