Integrating multicriteria evaluation and data visualization as a problem structuring approach to support territorial transformation projects

Abstract

Large freight or passenger transport projects are problematic and controversial because many financial, technical, environmental and social aspects need to be considered. Indeed, the interface between the transport project and territorial planning domains is generally the focus of considerable heated debates, which often develop into conflicting decision contexts characterized by a high level of complexity. This paper presents a possible response to these difficulties through an innovative approach that integrates the analytic network process and the interactive visualization tool. The approach is intended to be deployed as problem structuring method, with a view to creating a common language for the actors involved and a shared basis for generating fruitful discussions. The proposed approach was applied in the context of the German section of the Genoa-Rotterdam railway corridor within the Interreg IVB NWE Project ''Code24''. The reported application shows how the combination of visualization and real-time interaction with spatial data provided effective decision support to a multinational stakeholder group. More generally, the application presented in this paper aims to demonstrate the potential 123EURO J Decis Process (2014) 2:281-312 DOI 10.1007/s40070-014-0033-x of the approach for the selection of a transport improvement strategy within the content of territorial transformation.

How Can I Help You? Questioning the Role of Evaluation Techniques in Democratic Decision-Making Processes

“…Phillips [49] suggests the concept of "requisite decision model"; that is, a model whose form and content are both sufficiently complete to solve a problem. The notion of modeling can be applied to the structure of decision analysis, which requires that structural representations be sufficiently simple and non-complicated in order to grasp the essence of the problem while also producing solid insights [50]. Thus, structuring the problem emphasizes the formulation of statements by decision-makers about their goals, interests, and concerns, and it transforms these statements into clear and transparent representations that can be formalized mathematically [50].…”

“…In order to address all these aspects, the most important decision an analyst needs to make is therefore to choose an appropriate analytical structure before starting the numerical modeling and analysis [50].…”

“…This means that preference was given to the node that had the highest number of votes, and then among these weights the AA was determined. This last approach can be defined as a "majority" method, because it is somehow similar to a political election, where the winner is the party that obtains the highest number of votes (for an in-depth analysis see [49], while for application in an urban/territorial realm see [50,51]). …”

Evaluation of Interactive Website Design Indicators for e-Entrepreneurship

“…The plan with the highest weights is the result of the ANP, and it is the best plan for the decision-makers. Based on the above, when there are different plans of multi-objectives, multi-criteria, and multi-behavior decision-making, an ANP provides a highly compatible framework and ranking of the plans for decision-makers to select the best [43][44][45][46][47]. In addition, it can be applied to the analysis of importance of performance indicators of enterprises as the criteria of strategy execution and resource distribution [48][49][50].…”
