摘要:

由于现有的信息系统服务评估没有考虑用户评价,因此提出根据用户业务的重要程度对用户进行分级,基于分级用户的评价建立信息系统服务质量评估模型,采用层次分析法(AHP)和专家打分法确定相关指标权值. 仿真结果表明,受到分布式拒绝服务攻击(DDoS)后,优先保障高级用户业务可有效降低信息系统业务损失,提高信息系统服务质量评估值.

关键词: 用户评价, 用户分级, 评估, 层次分析法

Abstract:

To classify users according to the importance of their business with the information system and establish an evaluation model on service quality of information system based on classified users appraisal, the weights of relevant indexes are proposed using analytical hierarchy process(AHP) and expert scoring. Simulation shows that, under distribution denial of service (DDoS) attack, it can effectively reduce the loss of business of the information system and improve its service quality evaluation to ensure advanced users business firstly.

Key words: user's appraisal, user classification, evaluation, analytical hierarchy process
