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. Accordingly, 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 inconsistency 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.
