An Analytic Hierarchy Process Model For Landfill Site Selection

The demand for landfill disposal capacity is presently very high, despite environmental problems often attributed to this disposal technology. Accord­ ingly, the selection of optimal landfill sites presents a major challenge. I propose an analytic hierarchy process-based model for the optimal ranking of potential municipal landfill sites. The AHP approach also allows for inconsis­ tency evaluations of subjective preferences provided by decision makers. The model is applied to the selection of landfill sites in Apulia, a region in southeast Italy. This case study highlights the capabilities of the approach in solving a landfill site selection problem.
