| 摘要: |
| 明晰了受地理空间约束的业务流程的两个基本概念:地理位置与地理空间信息.首先,提出了地理空间约束思想,分析了地理空间约束的内涵,并在工作流元模型的知识基础上构建了地理空间约束的UML语义框架;其次,以形式化的方式提出了地理空间约束的业务流程建模方法(LAWF-net),并描述了LAWF-net模型转化为CPN可执行模型的规则,探讨了地理空间约束对流程建模的影响;最后,通过案例结合GIS系统来扩展CPN Tools,不仅验证了LAWF-net建模方法的可行性,而且实现了地理空间约束的业务流程的可视化. |

| Abstract: |
| This paper introduces a methodology towards enabling business process modeling with geographic and geospatial information. First, a comprehensive framework of geospatial constraints, formulated as a UML-based semantic model, is proposed. Next, a business process modeling language (LAWF-net) is designed to combine traditional control-flow constructs with the aforementioned geospatial constraints. To enable the execution of such models, a mapping to Coloured Petri Nets (CPN) is formulated. The proposed approach is implemented in the form of a CPN tool extension, and a case study is presented to show that the new approach is feasible in practice and can be combined and integrated with existing GIS systems. |
