摘要
该文通过对数据仓库系统的评价指标体系的分层,获得评价体系的三维指标矩阵,并提出了一个数据仓库系统评价模型。利用改进的基于熵值的TOPSIS算法,优化指标权重。将距离法应用于DW的多目标决策,采用理想解和负理想解的相对接近度对数据仓库系统做出综合评价。
By dividing the evaluation index system for data warehouse system into several layers,we can get a three-dimensional evaluation index matrix and setup an evaluation model of DW.Taking advantages of improved entropy-based TOPSIS algorithm,the weights of indices are optimized.We apply distance-method in the multi-objectives decision-mak-ing,and give a comprehensive evaluation of DW by using the distances from ideal and negative ideal solutions.
