The Simulation Assessment Of Availability For K/N Redundancy System Considering Failure Relevance Of Components, Haidong Du, Junhai Cao, Fusheng Liu, Xu Dan Dec 2019

The Simulation Assessment Of Availability For K/N Redundancy System Considering Failure Relevance Of Components, Haidong Du, Junhai Cao, Fusheng Liu, Xu Dan

Journal of System Simulation

Abstract: For the limitations existing in the system availability assessment based on the failure independent hypothesis,the availability assessment model for k/N system based on Copula function theory is built.A reliability evaluation method of fault-related system on the foundation of Agent technique is proposed. The completion of the simulation model from component entity to equipment entity resolves the question of reliability assessment existing in k/N system considering the effects of components relevance. And last, the evaluation results of system availability under different spare parts schemes are given under different material support program, the research results show that the relevance existing …


Evaluation Method Of Imminent Battle Situation In Air Combat, Huimin Cao, Anxiang Huang, Lei Xiang Feb 2019

Evaluation Method Of Imminent Battle Situation In Air Combat, Huimin Cao, Anxiang Huang, Lei Xiang

Journal of System Simulation

Abstract: In the state of air combat, the situation change rapidly. Quick and accurate assessment of the current situation and making decisions is the key to the victory of air combat and the preservation of own strength. Based on the specialty of the modern air battle and pelagic operation, this article adds the political factor, the pilot individual actual combat ability, and the formation cooperative tactical task to fight against the single constraint into the evaluation index system. This makes the evaluation more reasonable and comprehensive and closer to the actual combat, so as to provide more accurate basis for …


Simulation Assessment Of Degradation System Reliability Under Imperfect Maintenance, Haidong Du, Junhai Cao, Shen Ying, Shangru Teng Jan 2019

Simulation Assessment Of Degradation System Reliability Under Imperfect Maintenance, Haidong Du, Junhai Cao, Shen Ying, Shangru Teng

Journal of System Simulation

Abstract: For the state change characteristic of degradation system under imperfect maintenance, the common analysis method becomes useless. A simulation method for repairable system is presented. A change rule of system reliability was analyzed and a reliability assessment model was built on the foundation of components degradation process. A simulation tactics based on variable structure modeling was given which is realized through Agent technique. A maintenance optimization example was given for the determination of maintenance opportunity which is used to support the formulation and improvement of maintenance support program for repairable system.
