Abstract

In recent years, increasing waste has led to a shortage of space for land disposal site. Therefore, sea area final disposal at sea has become the predominant method. In this study, we propose a method of evaluation and site location with public participation for selecting alternatives of sea area disposal sites and related transfer stations. Firstly, we make it possible to evaluate the alternatives from various view points by public participants. Therefore, we introduce the L[lambda]-fuzzy measure method, which is composed of L[lambda]-fuzzy measure and a fuzzy integral as the method calculating total evaluation points of alternatives. This method can evaluate an alternative with positive features with a high score or without weak points, considering the assessments from various public viewpoints. We apply the AHP method for calculating the weight and evaluation point for each evaluation factor. Secondly, we apply our method for the practical problems of site location, and show that this method is applicable to evaluate and select alternatives.
