Abstract
Considering the trade-offs among the multiple objectives of economic efficiency, environmental risk, equity and administrative ease, the siting of a central treatment facility is attempted—a difficult but essential task in the regional hazardous waste management. For the quantification of each objective, the mathematical equations are formulated. Furthermore, the framework of the multi-objective planning technique in which the WRAP (Waste Resources Allocation Program) and Fuzzy Set theory are utilized is developed, to determine the appropriate alternative for the siting of long life public sector facility. As a case study, the developed technique is applied to the selection of the best site in the southwestern part of Korea, where the third new regional hazardous waste treatment center will be located. The effectiveness of multi-objective planning has been demonstrated, and the social and political factors affecting the siting are successfully quantified in a monetary value.
