改进的TOPSIS法在计算机综合评价中的应用

Application of Improved TOPSIS Method to Comprehensive Evaluation of Computer

针对TOPSlS法本身的缺陷.对其进行了两方面的改进.首先.采用序关系分析法来计算各评价指标的权重以避免采用客观权重导致的各评价指标重要性主次颠倒或人为指定权重导致的备评价指标权重重要性偏差过大的问题.其次,采用向量投影法来避免传统T()PSIS方法在方案评选过程中存在距离理想解近的方案与负理想解也近的问题.最后,应用改进的方法对多个计算机的综合性能进行评价,取得了合理的结果.

For the limitations of TOPSIS method, this paper makes two improvements. Firstly, it uses sequencing relationship analysis of each index to calculate the weight of the weight in order to avoid the use of objective evaluation result of the importance, Or man-made causes the specified weight of each evaluation index weights the importance of the problem of excessive deviation. Secondly, it uses Projection method to avoid the traditional TOPSIS method exists in the program selection process almost from the ideal solution and negative ideal solution programs are also close to the problem. Finally, it apply the method of multiple computers to improve the overall performance evaluation, and achieve reasonable results.
