一种基于软件属性相互影响和重要性的属性权重分配方法

摘要

To assess the weight of the software trustworthiness attributes,this paper proposed a new software attribute weight dis-tribution method.Firstly,it divided the software attributes into trustworthiness attribute model hierarchically.Furthermore,it in-troduced the concept of software attributes affection with each other and predicted the weight of attributes combined the weight distribution method based on attributes affection and attribute importance.Finally,it used a practical example of the attribute weights with the statistical analysis to elaborate the measuring process at length.The proposed method is a general mea-surement method which can be applied to different software trustworthiness attribute weight distribution.The method has certain practical significance and makes active exploration in software trustworthiness research.%为了确定可信度量中的属性权重，提出一种新的软件属性权重的分配方法。对软件属性模型进行分层划分属性，引入软件属性互相影响的概念，结合基于属性相互影响和属性重要性的权重分配方法，从两个层次对属性的权重进行综合预测，最后通过实际的例子对软件属性权重进行量化的分析，详细描述了该方法的具体过程。提出的软件属性权重的分配方法是一个通用的方法，对于各种软件可信度量中的属性权重可以进行相应的分析，在可信度量中软件属性权重的确定上有一定的实际意义和作了积极的探索。
