一种基于TOPSIS思想的改进灰色关联法及其在方案评估中的应用

An Improved Grey Incidence Analysis Method Based on Topsis Thinking and its Application on the Project Evaluation

提出了一种基于TOPSIS思想的改进灰色关联法,方法采用了TOPSIS思想,通过标准化处理,能够将灰色关联法给出的评估结果转换为,TOPSIS方法所要用到的与最优/最劣解的距离,从而给出一个稳定的评估结果,弥补了传统灰色关联法受全局极值影响大的缺点.经实例分析证明,方法可以应用于方案评估中,并能够得出可行、稳定、科学的评估结果.

An improved grey incidence analysis method is proposed in the paper, which adopts the TOPSIS thinking. By standardized processing, the evaluation result, which is elicited by Grey incidence analysis method, can be transferred to the distance to the best and the worst solution, that is needed by TOPSIS method. And so a steady evaluation result is elicited. The method offsets the disadvantage of the traditional grey incidence analysis method that is greatly influenced by the overall extremum. It is proved by the instance analysis that the method can elicit the evaluation result, which is feasible, steady and scientific. Also, it can be applied to the project evaluation.
