随机性混合数据评价技术的方法研究

在城市和环境规划等方案评价中,如何综合利用定性和定量信息是人们较为关注的问题。本文首先将方案评价中常见的定性信息分为三大类,并用数学式来描述各类定性信息,在此基础上,运用随机处理的方法对定性信息进行处理后与定量信息进行综合,以求得各个方案的优劣排序概率,并由此概率确定最优方案。这种方法克服了以往同类方法只能利用定性信息中的排序信息的缺点,从而使得方案评价更客观。最后,本文给出了方法应用的实例。

Research on the Technique of Stoachastie Mixed Data Evaluation

It is very important to deal with qualitative and quantitative information together in the evaluation of alternative plans, such as urban and environmental plans. In this paper, a new method, the technique of stoachastic mixed data evaluation is illustrated. In this method, the qualitative information is classified into three different types and all the types are described by mathematical formulas and treated by using random generator according to these formulas. Then, treated qualitative information is conbined with the quantitative information to evaluate the alternatives. This new method improves the mixed data evaluation techniques which are only able to deal with partial qualitative informatrion-ordinal information. At last, a case study is given.
