A Reliability Assessment Method of Urban Mass Transport Software Based on Markov Model

Urban Mass Transport (UMT) software is frequently used in multi-tasking, multi-module approach to software development, integration and expansion. Because differences in the architecture, function relatively independent of each task module, the implementation process of different software modules, the system reliability of the sensitivity of different software modules. Traditional reliability block model approach cannot identify the software modules of the system reliability impact, and therefore cannot for the corresponding module design, allocation of resources to provide any valid information. Therefore, this article presents a Markov model based software system reliability evaluation method, based on UMT to establish the reliability model of software architecture, analysis, system reliability, the reliability of the sensitivity of the module, identify the impact on system reliability large software modules, in order to achieve software reliability evaluation of UMT.
