一种基于多因子算法的评价指标优化方法

An Optimization Method for Evaluation Indicators based on Multi-factor Algorithm

从指标的关联性、重要性和有效性出发,利用灰色关联分析,提出了基于多因子算法的评价指标优化方法。该算法同时考虑多种因素对评价指标的影响,不仅保留了指标体系中的重要指标,也使各指标间相互独立,从而使得指标体系既全面又不冗余。在此基础上,通过有效性检验对指标体系进一步分析,确保了优化结果的科学性,给大型复杂系统评价指标的优化提供了新思路。

The paper proposes a solution for optimizing evaluation indicators based on multi - factor algorithm by using Grey Relational Analysis method, from the relevance, significance and validity of indicators. The algorithm not only keeps important indicators of the norm system, but also makes indicators independent from one another by taking into consideraton multiple factors that may impact evaluation indicators in order to build a comprehensive indicator system with little redundancy. Based on the above process, further analysis of indicator system is also made through validation so as to ensure the scientificalness of optimizing results and gives a new way of thinking for optimizing evaluation indicators of large and complicated systems.
