IT Service Combination Reliability Analysis Method and Simulation

Research the reliability of IT service combination of accurate analysis problem.A single IT service resources often cannot meet the service mission needs,and multiple IT service portfolios need new services to be derived,the deriving process is of much randomness and nonlinearity.Multiple derivation of project in dynamic combination,once the project exists between random conflict,will affect the dynamic reliability assessment of the accuracy of the models.The algorithm is based on the traditional single dynamic stability analysis of comprehensive model,Once the descendents of the new service projects conflict,it will cause a single model in the process of superposition ZhongLu great sex drop,and reduce the IT services combination reliability analysis accuracy.The paper put forward an IT services combination reliability analysis method based on rough set model.According to service attribute weight calculation attribute weights coefficient,a rough set model of analysis and decision was established to achieve the combination IT service reliability analysis.The simulation results show that the algorithm enhances the accuracy of analysis.
