The issue which lies at the heart of this paper is how best to inform the strategic decision making associated with the development of trans-European transport networks. Regrettably, the answer earmot match the succinctness of the statement of the problem. Indeed, almost as much attention will have to be given within the paper to deconstmcting and understanding what the problem is, as is devoted to setting out proposed solutions. Viewed from the perspective of decision research, this is not altogether surprising. It is commonly argued that the real value added by many decision support systems lies not directly in the ranking of alternative courses of action they might suggest, but in their ability to help decision makers reflect effectively on quite what problem they are trying to solve. What are the objectives they are seeking to achieve? Are the alternatives being considered drawn from too narrow a set of possibilities? Are proposed actions robust in the face of uncertainty about operating environments?
The work to be described is one component of a European Union Fourth Framework project being undertaken within the strategic component of the Fourth Framework transport programme. The project, EUNET-DECISION, has as its main objective the development of a comprehensive method for modelling and then evaluating the impacts of new transport initiatives, for example, the ranking of competing alternatives for investment in trans-European network (TEN) proposals. However in this paper we shall restrict ourselves to those aspects of EUNET associated with assessment of alternative courses of action, with only very limited reference to the regional economic and transport models. Essentially we shall address two questions. First, what type of decision making is the assessment tool meant to be supporting? Secondly, how is that support best effected?
