> 中文摘要: 流程的分布性要求工作流模型中时间约束可以采用不同的时间粒度来度量.为此,定义了工作流模型MG-TWF.通过多粒度相对时间约束、多粒度绝对时间约束及多粒度时间约束工作流网概念,从MG-TWF模型的静态建立阶段、动态运行阶段及模型的网结构方面描述其多粒度时间约束.并在此基础上建立了MG-TWF模型的多粒度时间约束工作流网、多粒度相对时间和多粒度绝对时间约束一致性问题的一般分析方法.最后给出一个具体MG-TWF模型的一致性分析实例.

Abstract:It is desired that time constraints of a workflow model can be measured by more than one granularities for distributed processes. Aiming at the multi-granularity time constraints problems, a workflow model, MG-TWF, is proposed. By the definition of multi-granularity relative time constraints, multi-granularity absolute time constraints and multi-granularity time constraints workflow networks, multi-granularity time constraints of MG-TWF are described from MG-TWFs static building stage, dynamic running stage and workflow networks structure. In addition, consistency analysis methods of multi-granularity relative time constraints, multi-granularity absolute time constraints and multi-granularity time constraints workflow networks are developed. Finally presented a case study is presented using the consistency analysis methods of MG-TWF.
