土地利用规划管理信息系统工作流建模研究

Research of Land-Use Planning MIS Basedon Workflow Modeling

工作流管理的主要特点是使管理过程自动化,使人及各种应用工具相互协调工作,达到"在适当的时候把适当的信息传递给适当的人"的目的.这恰好满足了土地利用规划管理信息系统的需要.本文在综合比较现有工作流建模方法、参考前人研究成果的基础上,结合土地利用规划MIS的业务特点,将工作流模型分解为4个紧密相关的视图:过程模型、功能模型、信息模型和组织模型,并为各种视图制定了表达方法.特别是在有向图的基础上,为过程模型设计的描述方法中,定义了GIS活动的表达.

Workflow management can satisfy the need of land-use MIS(management information system). It can provide automated management processes, coordinate the performance of both users and instruments, and transmit right information to the right person at the right time. According to the synthesis of diversiform model and the analysis of land-use planning management business, the definitions of workflow model of land-use planning MIS were proposed. They include four consanguineous and close-related views: process models, function models, information models and organization models. Descriptions of the four models were also put forward. Especially, in the expression of process models graphic notations for GIS activities were provided based on directed graph technology.
