Problems solved by technology

Software defects are the root cause of software failure, and software failure means that software is unreliable
At present, more and more software organizations pay attention to the collection and management of software defect data. At present, a certain amount of defect data has been accumulated, but the utilization of software defect data is not enough
Moreover, there is a certain relationship between software defects and reliability, but there is no corresponding method for using software defect data to serve software reliability design.

Abstract

The invention discloses a software reliability designing method driven by defects. According to the method, defect data of similar software are collected for recognizing potential defects in the software, make defect classification standards and establish a software detect model bank. On the basis of the detect model bank, causes of defects are perfected through software fault tree analysis (SFTA), and improvement measures are made according to the causes of defects, so that the implementation of a software reliability design technology is guided. According to the method disclosed by the invention, the implementation blindness of the software reliability design technology is overcome, the pertinence of a software reliability design is improved, the software reliability design can be carried out more effectively, defects can be prevented to the greatest extent and avoided as early as possible, the follow-up test and repair cost is greatly reduced, and the reliability of the software is improved more effectively.

Description

technical field [0001] The invention belongs to the field of software reliability engineering, and relates to a software reliability design method thereof, in particular to a defect-driven software reliability design method. Background technique [0002] Software reliability is one of the important attributes of software quality. Software reliability was proposed in the mid-1970s and developed in the mid-1980s. Around 1988, technicians were encouraged to use software reliability methods. Software reliability design is the key to ensure software quality and improve software reliability. The research on software reliability design method is an extremely important aspect in the field of software reliability engineering. [0003] Books and documents with different software reliability design methods have different contents, generally including implementing software engineering, simplified design, robust design, fault-tolerant design, software reliability design criteria, etc., b...
