公路管理单元动态划分技术与数据模型研究

管理单元是公路管理系统中一切管理工作的基本分析单位 ,是决策分析的对象 .管理单元划分得是否合理不但会直接影响到系统后期开发工作的繁简、难易程度 ,而且在很大程度上决定了系统决策分析结果的正确与否及其在实际工作中的实用程度 .在管理单元划分方面 ,目前尚无实用的原则和科学简洁的数据模型可供遵循 .为此在对公路管理系统的特点进行分析的基础上 ,提出了管理单元划分的原则和方法 ,并建立了相应的数据模型

Research on Segmentation Technique and Data Modeling in Highway Management System

In highway management system,the management segmentat io n is a basic unit of analysis and the object of decision through the whole manag ement work.It's very important to get a reasonable and correct segmentation for the development of highway management system and the decision analysis.But to to day,only very few segmentation rules and very simple data models were developed, which couldn't meet the requirement of dynamic segmentation in highway managemen t system(HMS).Based on the dynamic segmentation requirement in HMS,the dynamic s egmentation principles and corresponding modeling technique were developed in th is paper.
