| 摘要: |
| BPMN 2.0编排已成为描述业务流程间交互事实上的标准.BPMN 2.0编排面向流的特征，使之会产生控制流方面的语义错误.因此，检查编排语义正确性是BPMN 2.0编排建模工具所期望具有的功能.但是，BPMN 2.0标准规约中的编排缺少形式语义及相应的分析技术，这阻碍了对BPMN 2.0编排的语义分析.提出了一种映射，用于将BPMN 2.0编排转换为工作流网，使用Petri网来形式化定义BPMN 2.0编排的语义.借助Petri网的分析技术，这种定义的语义可用来分析BPMN 2.0编排的结构和控制流方面的错误.该映射和语义分析已被实现为一种工具.实验结果表明，这种形式化可以识别BPM AI过程模型库中编排的语义错误. |

| Abstract: |
| The Business Process Modelling Notation 2.0 (BPMN 2.0) choreography is a de factor standard for capturing the interactions between business processes. Flow-oriented BPMN 2.0 choreographies can exhibit a range of semantic errors in the control flow. The ability to check the semantic correctness of choreographies is thus a desirable feature for modelling tools based on BPMN 2.0 choreographies. However, the semantic analysis of BPMN 2.0 choreographies is hindered by the lack of formal semantic definition of its constructs and the corresponding analysis techniques in the BPMN 2.0 standard specification. This paper defines a formal semantics of BPMN 2.0 choreographies in terms of a mapping to WF-nets. This defined semantics can be used to analyze the structural errors and the control flow errors of BPMN 2.0 choreographies with analysis techniques of Petri nets. The proposed mapping and the semantic analysis have been implemented as a tool. The experimental results show this formalization can identify the semantic errors of choreographies from the BPM AI process model library. |
