基于i-BPMN的翻转课堂教学系统业务流程建模

i-BPMN modeling process for flipped classroom system

针对目前主流的BPMN建模方法对翻转课堂业务架构描述能力上的不足,基于TOGAF中ACF元模型提出一种完整覆盖系统业务架构本体的i-BPMN建模方法.集合目前应用较广的if-else语句以及IDEF建模方法,通过其与BPMN模型在ACF元架构描述上的契合点建立元模型映射关系,对BPMN模型中具有数据复杂性、功能层次性等特点的特殊任务进行建模补充,并通过迭代建模过程实现各描述模型之间语义、粒度的对齐.实验结果表明,采用i-BPMN建模方法能有效增强业务活动内部流程、逻辑、规则以及数据关系的描述,提供流程的完整理解,为后期系统开发明确要求.

Aiming at the shortcomings of the current mainstream BPMN modeling method for the ability to describe the business structure of flipped classroom system,an i-BPMN modeling method is proposed,which completely covers the ontology of the system business architecture based on the ACF meta-model in TOGAF.By collecting if-else statements and IDEF modeling methods,the meta-model mapping relationships are established through their conjunction points with BPMN in the ACF meta-architecture.In this way,special tasks with data complexity and other features in BPMN model are modeled as supplements,and the semantics and granularity of each description model are aligned through iterative modeling process.Experimental results show that using i-BPMN modeling method can effectively enhance the descriptions of internal process,logic,rules,and data relationships,provide a complete understanding of the flipped classroom process to make clear the requirements for the later system development.
