一种基于特定领域的可信构件度量模型

基于构件的软件复用是提高软件生产率和软件质量的有效途径，并在计算机系统中得到了广泛的应用。随着软件质量需求的提高，可信构件的研究也越来越受重视。构件的可信度决定了软件质量的高低，只有高可信度的构件才能够满足高质量软件的需求。因此，本文基于ISO/IEC25010软件质量模型，并结合构件本身的质量特性及其所应用的领域特性，建立一种基于某个特定领域的可信构件度量模型。在此基础上深入探究其度量指标的分析及选择过程，并用形式化的方法描述该模型的可信性。 

Trusted Component Measurement Model Based on Specific Areas

The reuse of component-based software is an effective way to improve productivity and quality, and it has been widely used in the computer system.With the improvement of software quality, the research of trusted component has got more and more attention.The credibility of component determines the quality of software.Only those components with high credibility will meet the need of high quality software.So, this paper introduces the ISO/IEC25010 software quality model firstly, then studies the properties of components, and finally a trusted component model based on specific areas is established.After that, this paper ex-plores the selection process of its metrics and describes the credibility of the model with the method of formalization.
