构造模糊层序树模式评价环境质量

本文应用模糊集合论理论和构造层次有序树方法,提出了环境影响优选评价的新模式。在建立数学模型过程中,给出了以加权欧氏距离和数学规划为理论根据的隶属度计算公式。利用本文所给出的模式对 JL 市四个化工区域的环境质量状况进行了综合评价,得到的结果较符合实际。该模式可以应用到综合排序评价的各种领域。

Evaluating Environmental Quality by Constructional Fuzzy Hierarchic Sequence Tree Mode

By fuzzy set theory and the method of hierarchy with sequence tree,anew mode is proposed in which environment affects optimum seeking evalua-tion.In establishing mathematical models,a calculating equation for attac-hing degree is given based on weighted Enidedan distance and mathematicalprogramming.Environmental quality circumstances of four chemical areasin JL city are generally evaluated by use of the mode given in this paper,which leads to relatively practical results.The mode can be applied to allthe scopes of general squencing evaluation.
