ABSTRACT

This chapter presents a different approach to spatial alternative screening. It describes a different approach to goal-oriented selection of decision alternatives that is based on computer graphics. In the framework of spatial decision making, Geographic Information Systems are a natural tool for analysis, selection, and the visualization of decision alternatives. The decision rules incorporating the ideas of compensation, trade-off, utility, and user-defined goal lie at the heart of Multiple Criteria Decision Making techniques. The efficiency frontier shows the trade-off between two criteria: how much the decrement of age is related to the increment of price if feasible alternatives from the convex hull are used. The information on proxy efficient trade-offs displayed in decision maps helps to identify a preferable goal. The selection of goal-proximate alternatives must take into account two possibilities: there exists at least one alternative that coincides with the identified goal and dominates it in the Pareto sense; or such alternatives do not exist.
