Embodiment Construction

[0069] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.

[0070] At present, the analysis of the impact range of software changes is carried out by nuclear power engineers. It mainly judges which basic items will be affected based on the engineer’s experience, and finally obtains the affected basic items. This analysis method is highly dependent on engineers and may cause analysis. There is a large error in the result, resulting in low accuracy of the range of influence of the change. This application proposes a method and system for identifying the impact range of software changes. Starting from the basic items of changes, the change impact analysis...

Abstract

The invention relates to a method and a system for identifying a software change influence range, belongs to the technical field of computer software, and solves the problems of poor precision and lowefficiency caused by analyzing the software change influence range in the prior art. The identification method comprises the steps of obtaining association factors on the basis of basic item identification of the software, basic items comprise function items and performance items of the software, and the association factors represent bearing content of association relations between the basic items; obtaining an incidence matrix of the software according to the incidence factor; wherein the incidence matrix of the software comprises incidence relations among all basic items of the software; comparing the basic items before and after the change to obtain a changed basic item; and performing change influence analysis in an incidence matrix based on the change basic item to obtain a change influence range of the software. Automatic identification of a software change influence range is realized, and the precision of an analysis result is improved.

Description

technical field [0001] The present invention relates to the technical field of computer software, in particular to a method and system for identifying the scope of influence of software changes. Background technique [0002] With the development of nuclear power technology, more and more digital products have entered the field of nuclear power, and more software technologies have been introduced. Based on the high security and high reliability of software and devices in the nuclear power industry, software used in nuclear power systems must undergo strict V&V (Verification and Validation). [0003] Current analysis of the impact of software changes is dominated by human analysis, relying on the analyst's personal experience. This method can identify the impact of changes between different development stages of the software, but it cannot obtain which functional items and performance items will be affected, that is, which basic items will be affected. Since the existing met...
