铁路物流信息系统安全等级评价方法的研究

摘要

This paper, based on the basic security factors of logistics information, brought up the security factors set, which was combined with the reality of Railway Logistics Information System. This paper used the method of DelPhi and AHP to calculate the weight of every factor. In the end, this paper fixed the single factor's security level set of Railway Logistics Information System using method and moddl of Fuzzy Synthesis Evaluation. Thereby this paper got the security score of Railway Logistics Information System, which was used to analyse the system security from quantitative aspect. This paper evaluated the Logistics Information System of CRE with this evaluation system and got a reasonable result.%论文在物流信息系统的基本安全因素基础上,结合铁路物流信息系统的实际情况,提出影响铁路物流信息系统安全的因素集合.利用专家打分法和层次分析法,计算出各因素的权重.再利用模糊综合评价方法和模型,计算出铁路物流信息系统各安全影响因素的单项安全等级集合,从而生成铁路物流信息系统安全评价分数,对系统的安全等级进行定量的分析.应用这一套方法,对中铁快运物流信息系统的安全等级进行评价,结果比较合理.
