Problems solved by technology

[0003] At present, there are three main types of software credibility measurement methods: the first category is software credibility measurement based on test data, such as Beihang University’s patent No. 200910082587.4 "a software credibility measurement and testing process-oriented evaluation method”, Tianjin University’s No. 201010164611.1 patent “Software Credibility Quantitative Evaluation Method Based on Software Defects”. The reliability measurement is carried out at multiple levels and stages such as design, implementation, and testing, and software credibility is reflected in these levels and sta...

Embodiment Construction

[0031] In order to achieve the above object, the technical process of the present invention is as follows: figure 1 As shown, the specific implementation is as follows:

[0032] (1) Determine the trustworthy attributes that need to be measured according to the reliability measurement requirements of aerospace software. The credibility of software is composed of a series of credible attributes, which can be comprehensively measured from two dimensions of quality and stage, such as figure 2 shown.

[0033] In the quality dimension, it is divided into three layers: management layer, user layer and product layer. The credibility of software can be measured from these three layers. From the perspective of management, the management layer cares about the process of software development, which reflects the quality attribute of the software process. , is the measurement of the process, such as whether the credibility review activities are organized according to the plan, whether th...

Abstract

The invention discloses an aerospace system key software evaluation method based on a credible attribute. According to the method, firstly, software credible attribute measurement pentagons of different levels and different stages are established, and measurement of the software credible attribute is achieved; secondly, measurement driving chains are established through the measurement pentagons, and a measurement radar picture is established through the measurement driving chains and comprehensively reflects the credible degree of software; finally, whether the software can be applied in a key aerospace system or not is evaluated by computing and comparing the area of polygons formed by connecting credible attribute measurement values and the area of polygons formed by connecting credible attribute required values. According to the method, the software credible attribute mainly related to the aerospace software serves as the measurement basis, a reference method is provided for comprehensive credibility measuring of the aerospace software, and the method can be used for evaluating whether the software can be applied to the key aerospace system or not.

Description

technical field [0001] The invention relates to a credibility measurement method, in particular to a credibility attribute-based evaluation method for key software of aerospace systems. Background technique [0002] Software reliability refers to the ability of a software system to provide continuous services when its operating behavior and results always meet people's expectations and are disturbed. In the fields of aerospace and military applications, improving software reliability is an important method to ensure the successful completion of key tasks, and the measurement of software reliability is a necessary means to verify whether software is credible. [0003] At present, there are three main types of software credibility measurement methods: the first category is software credibility measurement based on test data, such as Beihang University’s patent No. 200910082587.4 "a software credibility measurement and testing process-oriented evaluation method”, Tianjin Unive...
