一种基于云模型的综合评判模型

一个对象在目的指标上的综合评判结果取决于对象在各个分指标上得到的评语和各个分指标在评判中所占的权重。各分指标评语的模糊性和随机性以及如何把各分指标的权重考虑进来是综合评判模型的最大困难。文章利用云模型把不确定的评语映射为可细微变化的不同云滴，把各因素权重的变化映射为可修正的云的数学期望，提出了基于云模型的综合评判模型。

A Comprehensive Evaluation Model Based on Cloude Model

The comprehensive evaluation results of an object on its target index are decided by the comment of the object on each sub- index and by the weight of each sub- index in the comment. the fuzziness and randomness of each sub- index's comment and how to take the weight of each sub- index into consideration are the biggest difficulty for the construction of the comprehensive evaluation model. By using the cloud model, this paper maps the indefinite comment as different cloud droplets with fine variations, and maps the variation of each factor's weight as correctable mathematic expectation of the cloud, and thus puts forward a comprehensive evaluation model based on cloude model.
