基于云模型的多属性评价方法研究

Research on Multi-attribute Evaluation Method Based on Cloud Model

多属性评价在各行各业中的应用越来越广泛,评价的结论是决策者进行决策的基础和依据。利用云模型可以很好地进行定性描述与其定量数值之间的不确定性转换关系,提出了基于云模型的多属性评价方法,该方法区别于传统的多属性评价或综合评价只能得到一个笼统的综合结果且评价集单一的问题,不仅可以比较直观的看出各个属性的状态,还可以较客观的发现各个属性对整个系统的影响。经过实例可以看出,该方法的评价结果直观、可以显示出更多的细微信息,更加符合实际情况。

Multi-attribute evaluation （MAE） is more and more widely applied, conclusions of it are the basis of decision-making. Cloud model is a model of the uncertain transition between a linguistic term of a qualitative concept and its numerical representation. Using this advantage of cloud model, a MAE method was proposed. This method was distinguished form traditional MAE or comprehensive evaluation whose result is general with single comment set. This method can reflect not only the remark of each attribute intuitively but also whose effect to the whole system objectively. Testified by the experiment, results of evaluation are intuitionist with more details, and approach to the fact better.
