网络信息体系联动的影响因素重要性等级评估方法

Method for assessing the importance level of influencing factors of network information system-of-systems linkage

开展了网络信息体系联动的影响因素重要性等级评估问题研究。首先,描述了网络信息体系及其联动的概念,并从物理域、信息域、认知域和社会域4个方面提炼了网络信息体系联动的影响因素;然后,基于群决策理论,设计了联动影响因素重要度系数评估方法以及重要度等级映射方法,详细描述了评估方法中的领域专家群体意见一致性检验和权威度高且意见一致的领域专家子群体选取的方法步骤;最后,以典型案例仿真验证了所提出的网络信息体系联动的影响因素重要性等级评估方法的有效性和适用性。

The importance level evaluation of the influencing factors of the network information system-of-systems linkage is studied. Firstly, the concept of network information system-of-systems and its linkage are proposed, and the influencing factors of the network information system-of-systems linkage are extracted from the four aspects of physical domain, information domain, cognitive domain and social domain. Then, a method evaluating the importance coefficient of linkage influencing factors and mapping the importance rank which includes expert group opinion consistency test and selection steps of domain expert subgroup with high authority and consistent opinion is designed based on the group decision theory. Finally, the validity and applicability of the proposed method are illustrated by typical cases.
