Abstract

In modern software engineering, the component-based development approach has become one of the important trends in software development technology. The trustworthiness of components plays a vital role in developing component-based trustworthy software. If there exist defects in components, then the trustworthiness of the component will be reduced, and the trustworthiness of the software system will be influenced. In this case, it is necessary to measure the trustworthiness of the component in terms of the defect. In this paper, a trustworthiness measurement model of components will be proposed based on defects. Firstly, the defect types are formalized according to the component specification. Secondly, the weight allocation method of defect types is designed based on the correlation between defect types and experts’ evaluation. The value of the trustworthiness attribute is estimated by using the risk value of the defect and the weight of the defect type. Furthermore, the trustworthiness measurement model of the component is proposed, the corresponding algorithm is designed, and some algebra properties are proved. Finally, a case study is used to illustrate the application of the model.
