The Application of Fuzzy Analytic Hierarchy Process to the Optimal Selection of Sanitary Landfill Site

The selection of sanitary landfill site of municipal solid waste involves many complex influencing factors. By introducing fuzzy analytic hierarchy process (FAHP), fuzzy judgment matrix of the traditional analytic hierarchy process (AHP) is improved, the fuzzy consistency judgment matrix of the structure is constructed and the weight of the factors index of every layer is calculated out. Through multistage fuzzy operation, the final result of assessment weight of every optimal program is achieved. This approach reflects the relativity and fuzzy of the optimal selection process as well as make the evaluation work simple and clear. In the end, an example of the optimization selection of sanitary landfill site of municipal solid waste by means of the fuzzy analytic hierarchy process method is presented that demonstrated the feasibility of this approach.
