Comparison and discussion about different welght methods of comprebensive evaluation.

目的探讨在综合评价中不同确定权重的方法。方法比较主观赋权法——DelpIli法和层次分析法以及客观赋权法——熵值法,主成分法和因子分析法五种方法赋予生命质量评价领域权重值的优缺点。结果得出5种方法所计算的权重系数,并分析其所得结果之间的关系以进行优化选择。结论综合评价中不同的赋权方法各有优缺点,应用于本例,Delphi法更为方便、准确。

Objective To study approaches in weighting domains of comprehensive evaluation. Methods We compared the strongpoint and weaknesses by 5 methods. They are respective subjective method： Delphi consultancy and Analytic Hierarchy Process, objective method： Entropic method,Principal components analysis and factor analysis. Results To calculate the value of weight and compare the correlation coefficient among the five methods of weight in order to choose the best one. Conclusion The different approaches have both strongpoint and weaknesses. As this comprehensive evaluation, the Delphi consultancy is better.
