Research on the establishment of economic reliability analysis model based on computer Bayesian network

With the development and application of computer information system, the related problems of reliability are increasing, which directly promote the reliability research and quantitative analysis of information system. But there is still a long distance between the theory and the application of the establishment of reliability analysis model, the application situation is not satisfactory. Therefore, this paper mainly focuses on the research on the establishment of economic reliability analysis model based on computer Bayesian network. Based on a brief introduction of the related theories and technologies, the Bayesian network and its qualitative and quantitative analysis are elaborated in detail, according to Modern Bayesian network method with the characteristics of precise reasoning, intuitive understanding and good operating, the analysis results of system reliability calculation probability and system diagnosis can be obtained through the example analysis of economic information system. Experimental results show that the model can be easily used in reliability calculation and system reliability diagnosis of economic information system, and can be used in the reliability analysis of third party components and heterogeneous environment. © 2015, UK Simulation Society.
