Method and system for analyzing change risk of software repair

Abstract

The invention provides a method and system for analyzing the change risk of a software repair, and the method comprises a module division step: dividing software into different modules according to software functions, and determining the modules related to the software repair; a defining step: defining correlation according to the coupling degree between the modules, and when the function of one module is modified, defining the calculation coefficient of risk change of the module with different correlation with the module , and obtaining a correlation matrix M between the modules; a risk calculation step: analyzing modules involved when the software is changed, and designing a method to quantify a change risk; and a verification step: proposing a change risk analysis method, and providing a verification strategy for the repair work of the software according to the calculated change risk. According to the method, the risk is quantified by introducing the concept of change risk and change risk density. Verification after software repair is provided, and timeliness and reliability of software repair are guaranteed. Program design developers can be helped to understand the risk distribution condition and formulate a proper repair strategy.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a method and system for analyzing the change risk of software repair. Background technique [0002] With the continuous development of computer technology, the functions of software systems are becoming more and more powerful, and more and more functional modules are involved. There must be mutual correlation between each module. In order to meet the needs of the business, the software needs to be regularly upgraded, and to improve some functions, the software also needs to be improved to a certain extent, all of which involve the issue of software repair and verification. Due to the inadequacy of software repair verification, it is likely to introduce new risks, and even the newly introduced risks are more serious than the problems faced by the unrepaired software, which seriously affects the implementation process of software repair. [0003] In fact, the current main research...
