基于过程组件模型的流程引擎设计

针对目前工作流界标准众多、流程引擎和定义语言绑定、各业务领域重复开发流程引擎的现状，设计并实现一种基于过程组件模型的流程引擎框架。该框架采用流程虚拟机的架构设计，从多个流程语言提取流程的共性，摈除流程语言问活动类型的差异性，从流程定义中分离节点执行定义，从而支持多种流程定义语言。验证结果表明了该设计的可行性。这种过程组件框架能够降低从业务模型到流程定义语言之间的损耗，实现流程引擎与流程语言的解耦。

Design of Process Engine Based on Process Component Model

Aiming the defects of current workflow status, such as multifarious standards, process engine combing with defining language, designing process engine repeatedly in different domains, design and implement a workflow engine framework based on process component model. This framework better supports the transition from analysis process diagrams to executable processes, can handle multiple process languages, and give the benefit of loose coupling and higher extensibility in application. The feasibility was verified in the practical applications.
