摘要
提出一种基于政策(P)、愿望(D)和合同(C)的扩展Agent模型(PDC-Agent),并以它为基础,建立用于网络服务自动合成的方法体系·PDC-Agent根据3个因素(P,D和C),运用基于优先级的决策机制,理性地选择将要执行的服务和特性,并参与虚拟组织的建立和服务的合成·最后给出服务自组织的过程和实例分析·该系统能够适应商业需求的变化,在开放、动态、异构的虚拟组织环境中进行即时的服务集成·
A policy-desire-contract extended agent model (PDC-Agent) is proposed to establish automatic composition of web services. According to the three types of factors such as policies, desires and contracts, PDC-Agent rationally select the intended services and their properties by virtue of a preference-based decision-making mechanism, and participate in vlrtual-organization (VO) formation and service composition. The process of autonomic service composition and a case study are presented. This system can well adapt to the variation of business requirements and perform real-time application integration in the open, dynamic and heterogeneous VO environment.
