A normative proposal for obtaining a suitable multiattribute generalized cost in routing problems

Up to now, the routing problem with physical planning, (choosing the best route linking each pair of adjacent nodes belonging to a road network), has been solved only using an imprecise heuristic approach. In this paper we present a normative method which uses some proxy variables for modeling the main attributes, and is based on a set of rational axioms which provides a good framework for clearing Decision Maker's preferences and beliefs, following the paradigm of Decision Analysis. This method has been successfully applied in practical decision making.
