以电子政务、电子商务等城市应用为背景,针对这些应用中跨领域事件处置所涉及的异构、分布式资源、服务集成调度以及跨领域知识共享问题,提出了一个面向事件处置的、基于规则的信息服务集成调度模型.该集成调度模型具有4个分层结构,包括资源层(resource layer),知识层(knowledge layer),业务层(business layer)和表示层(representation layer).重点就知识层形式化业务规则的定义、资源和服务的引用以及规则引擎等给出了详细的设计和实现.最后,对该模型进行了验证,实现了一个城市应急联动应用中的统一接警事件处置原型系统.
Around city applications such as E-Government, E-Business, etc, event handling becomes a common activity. When handling an event in a city, people should focus on the task of integrating, conforming and scheduling heterogeneous, distributed resources from multi-domains, as well as sharing knowledge among different organizations. This paper proposes a rule-based distributed resources integrating and scheduling model for event handling. The model has a hierarchical structure with four levels: resource layer, knowledge layer, business layer and representation layer. Detail work on the knowledge layer is explored, which includes the definition of formal business rule, reference to resources in a rule, as well as the design and implementation of the rule system. Finally, an event handling prototype system of unitive alarm taking in for iEMS (integrated emergency management system) is implemented to validate the model.
