Research On Software Reliability Model And Application Of Network-based Social-security Audit Software

With the rapid development of computer technology, software deployed on the computer system is becoming more complex. People rely heavily on the correct performance of software, especially in key areas which have close relationship to human life and property. Software reliability modeling is a way to study software reliability.Software reliability modeling is a complex process, not only the architecture of the software is to be considered, but also the software development process and testing process are needed to take into consideration. In the Network-based Social-security Audit software development process, software reliability of the system is always an important component of the development work. Software reliability has a direct impact on the work efficiency of auditors and the quality of the results. The Network-based Social-security Audit system is a distributed system with the server in centre, and use an audit mode of data centralized multi-node parallel audit. On the basis of full analysis of the software architecture and audit mode, a concept of connection intensity is proposed. Connection intensity is described as a key factor which affects software reliability in the testing process. On the basis of non-homogeneous Poisson process software reliability model which has been proven successful, connection intensity is introduced in the form of COX's proportional hazard model. An imperfect debugging model with proportional intensity of connection intensity is built.Experimental results show that the model proposed here can describe the reliability growth process of the Network-based Social-security Audit system well.
