Method for carrying out automatic fault mode and influence analysis of software process

Abstract

The invention provides a method for carrying out an automatic fault mode and influence analysis of a software process. The software process is an approach for producing software, and the management of the software process is an important means for guaranteeing the software quality, thus the problems of organically combining each element of the software process, reducing the risk and the cost of software development and improving the quality of software products are concerned by a software process technology all the time. In the invention, on the basis of using a Little-JIL process modeling language for modeling the software process, defects and weak links of the software process are systemically analyzed, and influence which is probably caused by the defects and the weak links and potential reasons which cause the defects and the weak links are also analyzed so as to take corresponding measures, improve the safety of the software process, prevent faults, improve the quality of the software products and reduce the cost and the risk of the software development. The invention not only overcomes time consuming and error-prone defects of a conventional fault mode and influence analysismethod, but also realizes the effective combination of two complementary safe analysis methods of the fault mode and influence analysis method and a fault tree analysis method.

Description

technical field [0001] The present invention relates to a method for analyzing the safety of a software process and a method for modeling a software process with a process modeling language, in particular to a method for automatically analyzing the failure modes, effects and potential causes existing in a software process, as well as the failure modes and effects The effective combination of analysis method and fault tree analysis method. technical background [0002] With the development of computer technology, people pay more and more attention to the quality of computer software, especially high-security software, such as software in the aerospace field. The reliability of software is very important. How to develop reliable software is becoming more and more important. The focus of everyone's attention. However, through software development practices, people gradually realize that the quality of software products depends to a large extent on the process used in software ...

Problems solved by technology

This method does not propose a modeling method for the software process using the Littel-JIL process modeling language, and only analyzes the causal event and the combination of causal events that cause the fault event from the top down, and does not analyze the possible impact of the fault from the bottom up. Also not systematically analyzing all potential defects (failure modes) of the system, i.e. not integrated with failure mode and effects analysis methods
