| 摘 要： | 为了简化带有数据集约束的抽象网格工作流语言(AGWL)的工作流建立过程,提出了一种基于扩展面向对象Petri网(DOPN)建模并行数据流的方法.研究了AGWL并行数据流的特点,在此基础上对面向对象Petri网进行扩展,设计了基于扩展面向对象Petri网描述的并行数据流模型,之后定义一套从DOPN到AGWL的映射规则.最后通过一个应用实例对一个带有数据集约束的数据流建立DOPN描述,并生成AGWL数据流代码.该方法简化了AGWL工作流建立过程,并保留了流程验证和仿真的扩展性.

| Abstract: | In order to simplify the establish procedure of data collection restraint workflow on abstract grid workflow language(AGWL).A method of parallel data streams modeling base-on expanded object-oriented Petri net(DOPN) is presented.The characteristic of parallel data streams is studied.On this basis, object-oriented Petri net is expanded.And the model of parallel data streams based on expanded object-oriented Petri net is designed.Then a set of mapping rules from DOPN to the AGWL is defined.Finally, through an... |
