空间分析动态建模技术

业务系统开发过程中,为解决采用传统开发模式的专业空间分析模型与模型算法紧耦合而导致的复杂建模过程和难以有效复用的问题,本文提出一种空间分析动态建模技术,提出功能聚合的过程是空间信息模型实例化的过程:利用形式化语言和工作流建模规范构建业务规则,基于图论构建模型逻辑图的形式化转换规则,完成规则绑定;提出权限资源绑定模型,完成资源绑定。选取深圳市肾综合征出血热地理因素相关性定性分析专业模型验证空间分析动态建模技术的可行性。

A dynamic modeling technology of spatial analysis model

A professional model that adopts traditional development modes is tightly coupled to model algorithm,which leads to complex modeling process and difficulty in effective reuse.To improve this situation,this study proposed a dynamic modeling technology of the spatial analysis model,pointed out that the process of chaining functions is the instantiation process of a spatial information model,mainly including binding rules at the stage of conceptual model,binding functions at the stage of logical model,binding resources at the stage of physical model.The study used the specification of workflow modeling and formal language to construct business rules.Based on graph theory,formal conversion rule of a model logical graph was constructed.To solve the collaborative issue and authority control of dynamic workflow environment,the binding model of authority-resources was proposed.To test feasibility of the proposed methodology for quick building a professional spatial analysis model,the qualitative analysis model of correlation HFRS(hemorrhagic fever with renal syndrome) with geographical factors was developed.
