Abstract
The purpose of this study is to show the optimum planning of an area-wide treatment system for municipal solid waste. We analyzed the optimal scale on area integration and the most suitable combination of waste treatment scenarios at each of the integrated areas. Firstly, we considered indexes of economical and environmental efficiency in order to design the system taking account its multipurpose optimization. Furthermore, this paper described a formulation of multipurpose fuzzy IP (Integer Programming), which was expressed by the linear membership functions and the fuzzy decision, and proposed a method using GA (Genetic Algorithm) to find the optimal solution to the fuzzy IP problem. Finally, we conducted a case study in order to show the validity of our solution method. As a result, it was revealed that our model building and solution were useful for striking a happy medium in the area-wide waste treatment planning.
