Abstract

The invention discloses a software system reliability prediction method which comprises the following specific steps: performing functional decomposition on software to decompose the software into software modules; extracting factors influencing the reliability of the software module according to inherent characteristics and development process characteristics of the software module, and determining the influence degree of each factor on the reliability of the software; building a module reliability prediction model, and finishing module reliability prediction; and establishing a software reliability prediction model, and predicting the software reliability by utilizing the obtained module reliability. The software reliability prediction method and device, the computer equipment and the storage medium are used for early prediction of software reliability, the reliability of software is improved in the software development process, and the software reliability prediction method and device have important significance in achieving resource planning and quality prediction.

Description

technical field [0001] The present invention relates to the technical field of software testing, and more specifically relates to a software system reliability prediction method, device, computer equipment and storage medium. Background technique [0002] There are three elements in software reliability prediction: software reliability model, parameter estimation method (algorithm) and data. Since Jelinski and Moranda proposed "Software Reliability Prediction Model" in 1972, dozens of models have been proposed successively after the research of many scholars. Software reliability prediction and evaluation models play a very important role in estimating software reliability, but these software reliability models use the failure data obtained during software operation and testing to perform reliability analysis after the software development is completed. It is estimated that it only estimates the reliability index of the software, and cannot improve the reliability of the so...
