铁路信息资源的层次模型研究

Research on a administrative-levels model for railway's information resources

目前铁路信息资源在不同的维度上进行分层的方法尚存在结构不完善、分层次数不科学、分层标准不统一的问题,降低了信息资源分层的效率系数,使得大量的信息资源的应用不充分或不方便或干脆无法使用。本文在对铁路信息资源现状分析的基础上,借助层次模型理论,提出了铁路信息资源4层次模型,利用映射理论描述了各层次间的映射对应关系,最后分析了该模型在铁路信息资源开发中的应用,以满足铁路信息资源开发利用的需要。

There still exist many problems, such as the faultiness of layered structure, unscientific of layered degree , disunion of layered standard, etc. This paper gives a careful analysis about the existing situation of railway's information resources and puts forward a fouradministrativelevels model, and presents the mapping relations of each administrativelevel based on mapping theory. This will provide good proposals for further development railway's information resources.
