The Design And Implementation Of The Land Of Airport Plan And Use System Base On Workflow And GIS

The traditional way to plan the airport land is hand-worked. It has many disadvantages, such as too enormous workloads, too many steps, too long duration, too low work efficiency and frequent mistakes. In addition, it is difficult to support the visual decision-making because of wanting visual tools and geographic information system. With the fast development of Chinese economy, there are many new airports will be built, and the traditional way is not able to meet the requirement of the land planning of airport. In the new epoch, the construction of the land planning of airport system not only needs a good office automatic system, but also needs a powerful visual tool and a Geographic Information System (GIS) platform. At the same time, workflow is using widely in companies due to its abilities for optimizing and managing process, and GIS which was invented several decades ago has excellent abilities for describing, storing and output the spatial information. Therefore, it is an inevitable tendency to combine the workflow with GIS technology to plan the airport land system.First, in this dissertation, several kinds of technique, such as the Software Engineering, workflow, GIS technology and the way to plan the airport land are simply introduced, in succession, the disadvantages of the traditional way to plan the airport land and the necessary to use the knowledge of Software Engineering, workflow and GIS technology are analyzed .Secondly, in this dissertation, workflow, the reference model of workflow, the architecture of workflow manage system and JBPM are introduced detailedly. GIS and MapXtreme Java Edition 4.8.0 are discussed. Then, spatial database are related.Thirdly, the background, the principles, the goals, the functions etc of the airport land system base on workflow and GIS technology are discussed. The design and implementation of the part of process management with workflow and the part of map display and control are explained detailedly. In addition, the design and implementation of this system are guided by the rules of software engineering. The images of the running system are displayed in the part of introduction of system implementation.Finally, the research work is summarized and the study in the future is prospected .
