基于客观赋权法的嵌入式软件可信性评估方法研究

Objective weighting approach based embedded software trustworthiness evaluation method

以基于证据推理方法的嵌入式软件可信性评估理论为基础,分析需求驱动的嵌入式软件可信性评估过程,并针对评估过程中存在的可信指标间相对权重难量化问题,提出一种基于可信证据熵的客观权重计算方法,用以改进传统方法中常用的主观判断方式。算例分析验证了该方法的合理性和有效性。

To discuss and explain the basic scientific problems in embedded software trustworthiness evaluation,the paper proposed a novel requirement-driven process model of software trustworthiness evaluation.Also,this paper set up a calculation method for indexing relative weight by trustworthy evidence entropy,which overcame the shortage of traditional method,in which the weight was set up by subjective manners.The experimental results show that the validity and rationality of the proposed model and it is suitable to embedded software.
