Software Reliability Evaluation Method Based on a Software Network

This paper proposes a method for the comprehensive measurement of software quality and reliability based on the complex network theory. The quality of the overall network structure of software is evaluated in terms of modularity, hierarchy, complexity, and fault propagation. The importance and reliability risks of the software module are combined to evaluate the overall reliability risk of software. According to the historical defect information of software, the characteristics of the defect node are analyzed to predict the software's current version of the high defect risk module. The software reliability level is comprehensively evaluated by combining the software's overall structural quality, reliability risk and defect risk.
