Problems solved by technology

[0003] It can be seen from the above description that when software defects reach the running stage, there will be a risk of software failure. Therefore, the concept of software reliability appears in reality. Software reliability refers to the software under specified conditions and within a specified time. The ability not to cause system failure, the generation of reliability, it is necessary to analyze the reliability, but there is no good method for reliability analysis.

Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0044] figure 1 It is a schematic flowchart of the analysis method of software reliability in the first embodiment of the present invention. In specific implementation, the software in the embodiment of the present invention can be the digital system software of a nuclear power plant.

[0045] like figure 1 As shown, the method of the present embodiment includes:

[0046] Step S13, acquiring and screening the number of defects in the software testing phase; Step S14, fitting the screened defects according to time to obtain the fitting result;

[0047] In step S15, trend analysis is performed according to the obtained fitting results to obtain the frequency of software failures under the test conditions.

[0048] Wherein, in step S13, acquiring and screening defect data in t...

Abstract

The embodiment of the invention discloses a method for analyzing software reliability and a system thereof capable of analyzing the reliability of software effectively. The method comprises the following steps: obtaining and screening the number of defects during the software test period; fitting the screened defects in chronological order to obtain a fitting result; performing a trend analysis on the obtained fitting result, obtaining the failure frequency of the software under the test condition.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a software reliability analysis method and system. Background technique [0002] Generally, the life cycle of software can be divided into three stages: software design, software testing, and software operation. Among them, the software design stage refers to the stage of developing software codes. Usually, various defects will appear in the software design stage. Defects in software are inherent, errors in software compilation, or code errors. The testing phase of software can be divided into two types of testing: functional testing and performance testing. Among them, functional testing refers to testing whether the software can realize its functions; performance testing includes load testing and stress testing, which refers to verifying the performance of the software in Whether repeated use under normal environment and complex system conditions can still meet the performance indic...
