动态联盟企业的组织建立是一个复杂而又系统的任务，其中存在大量的问题急需决策支持系统给予决策支持。而动态联盟多企业合作的特点，决定了这其中大部分问题的决策是在动态联盟盟主和伙伴企业之间群体协同求解的。因此，本文在分析了动态联盟组织建立过程中决策问题的基础上，提出了面向动态联盟组织建立的分布式群体决策支持系统的结构框架，并阐述了其运行机理。 The establishment of a dynamic alliance enterprise is a complicated and systematic task, in which a large number of problems urgently need decision support system to give decision support. The characteristics of dynamic alliance and multi-enterprise cooperation determine that the decision-making of most of these problems is solved by groups of dynamic alliance leaders and partners. Therefore, based on the analysis of decision-making problems in the process of establishing dynamic alliances, this paper proposes a structural framework for distributed group decision support systems established by dynamic alliances, and expounds its operating mechanism.
