摘　　要：在可信性概念的基础上,结合电子信息系统的特点给出电子信息系统可信性概念及其形式化描述,建立层次结构的电子信息系统可信性模型及其评估模型;通过分析电子信息系统可信性属性,应用层次分析法的思想,建立电子信息系统可信性的指标体系;综合当前系统评估的主要方法,提出针对电子信息系统可信性特点的评估方法———基于熵权的电子信息系统可信性多层次综合评估法;最后,应用该方法对某电子信息系统的可信性进行了评估,验证了该方法的有效性。On the base of the concept of the dependability and combining the characters of electronic information system,it not only puts forward the definition of the dependability of electronic information system and its formal description,but also portrays concept model and evaluation model of the dependability of electronic information system.Through analyzing the factors related with the dependability,the indicators of dependability is established by AHP.Based on the synthesis the current primary methods of system evaluation,the multilayer synthesis evaluation method of the dependability of electronic information system based on entropy weight,is put forward which was used to evaluate the dependability of a system to prove that the method is effective.
