This paper presents a new, transformed multi-criteria model for selecting a landfill site. The selection of a landfill site was treated as a problem of meeting several criteria from communal, construction, environmental, economic, and aesthetic aspects, for the reason of finding an optimal solution for a landfill. In that aim, selection of a landfill site by selecting the performances of criteria and alternatives is a very important decision for successful environmental protection. The paper depicts the transformed procedure on the principle of maximal value and selection of a landfill site done by the weighted value on the basis of geometric mean. An illustrated example also is presented.
