Abstract: Business Process Management (BPM) is an effective strategy for companies to ensure continuous improvement of business processes and adapt to business changes,where business process modeling is the key to optimize BPM.Business Process Management Notation(BPMN) is a visual business process modeling language which provides process interaction,exception handling and semantic compensation in the modeling process.Although BPMN is applied in many fields,it is difficult to express some complex business scenarios in industrial Internet context in an intuitive way,which increases the communication cost between modelers and business personnel.The existing works on BPMN extension focus on extending the attributes of original elements in BPMN with annotations for explanation,but the expressiveness is still insufficient and many annotations make the process models complicated.In view of this,the business process modeling elements were extended based on BPMN2.0 by proposing a generic extension mechanism and implementation method.Based on the method,new modeling elements and attributes could be extended to meet the business requirements of different application scenarios.Finally,the effectiveness of the extension mechanism was illustrated by case study.The proposed extension mechanism provided a universal reference framework for the extension of other business process modeling elements.
