Multi-Objective Combination Methods

Spatial multicriteria decision rules can be categorized into multiattribute and multiobjective decision rules. Spatial multiobjective combination methods make a distinction between the concept decision variables and decision criteria. These two elements are related to one another by a set of objective functions. Also, the set of alternatives is defined in terms of causal relationships and a set of constraints imposed on the decision variables. The alternatives are defined implicitly rather than given explicitly as in the case of multicriteria decision rules. The attributes can be thought as the means or information sources available to a decision maker for formulating and achieving his or her objectives. In other words, the objectives are functionally related to or derived from the attributes.
