Management Methods And Execution Engine Of Business Process Based On Event

With the rapid development of internet technology and the Saas conceptproposed, the traditional services continue to change.Faced with the rapid growth ofservice resource providers and customers who need of services in the internet,wepropose an innovative service model named BIRIS (BIlateral Resource IntegrationService, BIRIS), introduce a third party smart service platform namedBIRIS–SSP.The platform uses resources integration, service process orchestrationtechnology and so on for providing customers and providers with services.We mayrefine and abstract the service process provided providers and customers by theBIRIS–SSP,then Through the workflow model them,so that the part of the businessprocess can be automated in order to improve the efficiency of the service, increasecustomers and providers satisfaction.this paper is in-depth study ofWorkflow,intorduce event-driven mechanism to adapt to the reality of enterprisebusiness processes which have complex and unpredictable characteristics.The author in-depth study of workflow technology by a large number ofreferences, including a description of the concept of the workflow reference model,event-driven mechanism. And the paper uses wisdom service platform as testenvironment, and analyzed the characteristics and constraints of configuration,implementation and supervision of the process based on BIRIS SSP.this paper focuses on the event-based business process management methods,including the event definition and the formal description of event, defines the eventclassification, event operations and event expression,proposes the synthesis ofcomplex events and the detection algorithm and explicitly ECA which is the rules ofeventsimplementation,and interduce the detailed mechanisms of event’s generation,processing and consumption and dynamic routing in the process instance under thismechanism.And this paper studies depthly the relationship between events andprocesses, between the soft components and processs and between processes andprocesss, presents the method of the definition of Workflow events, and definesevent publish and subscribe, and discusses the process model dynamic bindingsoftcomponent technology and realization. The author finally completes workflow processing mechanism on theplatform,a service system is builded on the BIRIS-SSP as the experimentalenvironment of the paper, to implement and apply the research.after the system isestablished, it uses resources gathered on the platform to support creation andconfiguration of process models,and definition,publish and subscribe of event,aswell as regulation and operation of the process instance,achives staple anddistribution services.
