目标层次法在城市固废综合处理厂选址中的应用

研究城市固废综合处理厂的厂址选择问题,以建立一套合理且客观的分析程序来寻找最优的固废综合处理厂设置位置,并使所需的相关成本及对环境的负面影响降到最低.为此,本文提出了一目标层次方法,该方法首先对可能潜在的厂址进行可行性筛选;其次,对选择的可行性厂址通过多准则决策分析方法进行进一步评估.以0/1组合优化模型(上层)结合多属性简单加权评估函数(下层)进行求解,以获得最优方案.通过昆明市废弃物综合处理厂选址的实例,说明了这一决策方法的应用.并给出了目标成本最小化及整个系统的计算结果.

A Hierarchy Approach of Objectives for Municipal Solid Waste Comprehensive Disposal Plant Site Selection and Its Application

The issue of municipal solid waste ( MSW) was studied that comprehensive disposal plants site selection in order to establish a set of reasonable and objective analysis process in finding the best disposal plant site by minimizing costs and environmental impacts. Therefor, a hierarchy approach of objectives was proposed that for the site selection problem. First of all, several potential sites need to be screened as a set of feasible alternative sites. Second, those alternative feasible sites will be further evaluated via the multi-criteria decision making methods. For the evaluation process, we solve a 0/1 combinatorial optimization problem at the upper level and proceed the multi-attribute simple additive weight evaluation function at the lower level to get the optimal solutions. An example of waste comprehensive disposal plant site selection existing in Kunming City, China is followed in the end. Computational results both of the cost minimization and of the whole systems are also provided.
