Considering the characteristics of multi-objective and fuzziness in suitability evaluation of municipal solid wastes landfill site

an approach of multi-layer and multi-objective fuzzy sets for complicated system is presented. The fuzzy pattern recognition model is combined with fuzzy comprehensive evaluation model to evaluate and optimize municipal solid wastes landfill site. In the model

an adapted analytic hierarchy process (AHP) and relative membership function are proposed to calculate respectively the weights of evaluation indexes and the optimal fuzzy recognition matrix. Finally

the proposed approach is successfully applied to assess a given solid wastes landfill site in Shanghai area. Moreover

the procedure can also be applied for evaluation and optimization of the engineering sites for other purposes.
