基于D-S证据理论的信息融合软件的设计与开发

Software Design and Development of Information Fusion Based on D-S Evidence Theory

基于D-S证据理论,采用手工方式融合多源信息,具有劳动强度大、计算结果出错概率高等问题。针对这些问题,本文设计、开发了基于D-S证据理论的信息融合计算分析软件(DSIF)。DSIF软件以Delphi7和SQLServer2000等为开发工具,采用模块法设计思路,具有使用方便、维护简单、稳定性好、通用性强、扩展性好等特点。同时,该文依据D-S证据理论信息融合的特点,给出信息融合计算分析流程图及DSIF的体系结构。以水质监测数据为对象,DSIF软件为工具,进行信息融合,来说明DSIF软件的特点及其功能。

By means of manual labour,multi-source information is fused on D-S evidence theory,which brings some problems such as high labour intensity,wrong-probability of computing result and so on.Based on the problems,software of information fusion based on D-S evidence theory(DSIF) is designed and developed in the paper.With development tools including Delphi 7 and SQL Server 2000,modular method is adopted in the DSIF design in order to make the software have the advantages such as manipulation facility,maintenance simpleness,good stability,better generality and expansibility.By the characteristics of information fusion based on D-S evidence theory,flow chart of information fusion computational analysis and the architecture of the DSIF are proposed.By the DSIF,water quality monitoring data are fused to illuminate its advantages and functions.
