摘　　要：分析了动态联盟企业对信息系统适应性的需求 ,提出了面向动态联盟的工作流概念模型。该模型的建立 ,采用了活动分解与分层递阶方法 ,将工作流系统分解为不同层次的方法 ,这一方法使每一工作流系统的问题复杂度得到降低 ,并增强了系统的重构能力。在此基础上 ,结合基于 CORBA的功能封装与代理技术 ,建立了适应性工作流的系统框架。该框架可支持动态联盟信息系统的重构。This paper analyses the requirements on the adaptability of the information system under the virtual organization environment. Then a workflow conceptual model to enable virtual organizations was proposed. This model is based on activity decomposition and hierarchical methods, i.e., a complex activity may be decomposed into several sub-activities and an overall workflow system can be built on several levels. This model reduces the complexity of each workflow system and improves the reconfigurability of the overall system. Based on the model and agent technology and the function encapsulation of CORBA technology, an adaptive workflow framework was built. The framework supports the reconfiguration, software reusability and scalability of the information system of virtual organizations.
