Land evaluation should be regarded as a multiple objectives evaluation resulting from the overall assessment of varying site conditions. As a method of formulating these evaluation processes, the multiattribute utility function (M. U. F.) is considered relatively effective. However it had previously been considered very difficult to conduct research on model construction due to the complex procedures involved with M. U. F. -aggregation methods had not been clarified. In the present study, the following were investigated for constructing evaluation functions, to solve these problems: procedures verifying independence among variables, and methods utilizing orthogonal arrey to determine evaluation function parameters. Comparative analyses between the conventional and the newly constructed methods were also carried out. Furthermore, the application of this method to some actual case studies were attempted. Thereby it was proved that this method is practical use and useful.
