Research And Implementation Of Event Driven Multi Process Collaborative Interaction Platform

With the development of modern enterprise informationization,the business process management has been introduced into the management and operation of modern enterprises,and the business process collaboration and interaction among cross enterprise business process management systems is of high practical value.This thesis focuses on the event driven multi process interaction,which includes formal verification of BPMN process,event routing and message filtering for business process engines and centralized design and deployment of business processes.Centralized design and deployment of multi process interaction is the most basic research of event driven multi process collaborative interaction platform.An open source tool which called BPMN2Modeler has been deeply studied in the process of research.This thesis implements nested processes modeling,event modeling and other functions to solve the issues related to the centralized design of processes through the modification of the meta-model and using the extension mechanism of the tool.The modeling tool tasks one process as the unit for remote deployment.This thesis extracts and generates executable business processes from the collaboration diagram through the way of making redundant copy to solve the problem of process segmentation deployment.Routing and filtering of event messages are important issues that need to be resolved in the event driven multi process interaction.This thesis takes the jBPM as the business process execution engine,and it uses the WorkItemHandler mechanism of jBPM to integrate the existing event based message middleware into the jBPM process engine to realize the message routing and forwarding among engines.The thesis introduces the detail of how to map BPMN business process to Petri net model,and showed the theoretical algorithm about security,reachability and deadlock verification of Petri network.And then the detail of design and implementation of the process validation was described.Based on theoretical and technological analysis and research,this thesis implements the event driven multi process interaction platform and tests the function of platform and builds a simple user case to verify the tool.Experimental results show that the platform can meet the business needs,which achieve the goal of desired functional requirements.
