城镇污水处理厂清洁生产等级评价二元语义模型与方法

为解决城镇污水处理厂清洁生产等级评价问题,采用定性分析与定量计算相结合的方法,着重构建了城镇污水处理厂清洁生产等级评价指标体系及其权重确定方法;利用线性加权综合评价方法、模糊数学和二元语义概念,建立了城镇污水处理厂清洁生产等级评价模糊综合模型,并据此提出级别特征值概念,进而建立城镇污水处理厂清洁生产等级评价的二元语义模型与方法.实例计算分析说明,文中建立的清洁生产等级评价二元语义模型与方法可操作性强,等级评定结果比采用隶属度最大原则更直观、更便于解释,具有很好的应用与推广价值.

Two-tuple semantic model and method of cleaner production grade evaluation for town sewage treatment plants

The cleaner production grade evaluation problem of wastewater treatment plants was studied through the method of combining qualitative analysis with quantitive computation. The index system of cleaner production grade evaluation for urban sewage treatment plants and corresponding weights’ determination method were proposed. The fuzzy comprehensive model of the cleaner production grade evaluation for town sewage treatment plants was established and the two-tuple semantic model and method through introducing the concept of the grade eigenvalue were developed through using the linear weighted comprehensive method, fuzzy mathematics and the concept of two-tuple semantic. It was illustrated with a real example that the established two-tuple semantic model and method of the cleaner production grade evaluation were more operational, intuitionistic and easily explained. Thus, the two-tuple semantic model and method proposed in this paper were of good applicability and generalization value.
