Problems solved by technology

However, the current analysis methods mainly use BDD, minimum path set, minimum cut set, and fault tree to describe the system reliability relationship. This description method is difficult to reflect the correlation and diversity of unit states, and is not suitable for cold storage. State-related reliability logical relationship limits its application range

Embodiment Construction

[0056] Below in conjunction with embodiment the present invention is described in further detail:

[0057] Phased-Mission Systems (PMS) refers to systems that can divide the mission cycle of the system into a series of continuous disjoint independent time periods according to the differences in system configuration, mission success criteria, and subsystem behavior. These consecutive disjoint independent time periods are defined as phases. Since it was proposed by Esary and Ziehms in 1975, it has attracted the attention and research of many scholars. The current PMS task reliability analysis methods can be roughly divided into two categories: analytical method and simulation method. Analytical methods mainly include methods based on Markov and methods based on BDD (Binary Decision Diagrams). The former method is based on the theory of stochastic process, which may have the problem of state space explosion, which limits its practical application. The latter method is only app...

Abstract

The invention discloses a multi-state multi-task system reliability parameter analyzing method. The method comprises the steps that AS trees are utilized to describe logic structure relation of each stage of a multi-stage task system, and a multi-state multi-stage task system simulation algorithm is given based on a discrete event simulation thought. The simulation algorithm can calculate multiple parameters such as multi-state PMS system reliability, required input parameters are few, programming realization is simple, the simulation algorithm can well describe complicated behaviors of the multi-stage task system, multiple reliability parameters for knowing a system reliability parameter can be obtained, and the simulation algorithm has very strong universality and practicability.

Description

technical field [0001] The invention belongs to the field of system reliability analysis algorithms, and in particular relates to an analysis method for reliability parameters of a multi-state and multi-stage task system. Background technique [0002] As modern systems become more and more complex and intelligent, the operation of the system is no longer a single process, but includes the transformation of multiple functional processes, or the process of forming a new system by reorganizing units at different stages, such The system is called a multi-stage mission system (phased-mission system, PMS). A multi-stage mission system means that the mission cycle of the system can be divided into a series of continuous disjoint independent time period system. These consecutive disjoint independent time periods are defined as phases. [0003] The current PMS task reliability analysis methods can be roughly divided into two categories: analytical method and simulation method. Ana...
