The aim of this thesis was to develop a methodology and a toolbox capable to support a negotiation process for an environmental multi-objective problem. The first part of this thesis focuses on the explanation of some of the existing Advance Visual Analytics, visual frameworks that are useful to discover innovative solutions to support stakeholders’ interaction with multidimensional data sets. Starting from solving a two-dimensional problem using the “Pareto Frontier” approach, then going through diverse techniques that can do representations of more than two dimensions. At the end of this part is done a comparison between the tools able to work with an environmental multi-objective problem data structure. The comparison gives as a result that the best technique is the Parallel Coordinates Plot, reason why ParPlot; a toolbox designed in this thesis, was developed based on this technique. The next part of the thesis presents a methodology developed for an effective use of ParPlot as a support in negotiation processes. Different steps have been identified, starting from the analysis of the data, up to the selection of the most feasible solutions, and finally to the presentation and sharing of the results obtained. After the development of the toolbox and the methodology, these were tested in a real case scenario. The case selected was the IMRR (Integrated and sustainable water Management) project on the Red-Thai Binh River basins, located in the north of Vietnam. The testing was done during a work session with three researchers acting as stakeholders, looking to analyze and select the best solutions according to their own objectives, arriving to a group of interesting solutions.

L’obiettivo della seguente tesi è stato di sviluppare una metodologia e un toolbox in grado di sostenere un processo di negoziazione per un problema ambientale multi-obiettivo. La prima parte verge sulla spiegazione di alcune delle strutture già esistenti di Advance Visual Analystics che sono state utili per indagare soluzioni innovative di supporto all’interazione degli stakeholder con set di dati multidimensionali. Si è partiti dalla soluzione di un problema bidimensionale utilizzando l’approccio “Pareto Frontier”, per poi affrontare diverse tecniche in grado di rappresentare più dimensioni. In conclusione è stato condotto un paragone tra gli strumenti in grado di lavorare con strutture di dati di problemi ambientali multi-obiettivo. Il confronto ha evidenziato come migliore tecnica quella del “Parallel Coordinates Plot”, che, di conseguenza, è stata la base del toolbox successivamente sviluppato nell’elaborato di tesi, il ParPlot. Lo step successivo è stato, quello di sviluppare una metodologia efficace per l’utilizzo di ParPlot come supporto nei processi di negoziazione. Sono stati individuati i diversi passaggi da affrontare; partendo dall’analisi dei dati, fino alla selezione delle soluzioni più fattibili e, infine, alla presentazione e alla condivisione dei resultati ottenuti. Si è quindi testato il toolbox e la metodologia in un caso reale. È stato deciso di far uso del progetto IMRR (Integrated and Sustainable Water Management), un caso riguardante i bacini del fiume Red-Thai Binh, situato nel nord del Vietnam. La fase di test è stata effettuata in un’unica sessione di lavoro, con tre ricercatori in funzione di stakeholders, che hanno analizzato e selezionato le soluzioni migliori secondo i propri obiettivi, arrivando a un insieme di soluzioni interessanti. In conclusione dell’elaborato, è stato descritto il toolbox dal punto di vista tecnico ed è stata effettuata un’analisi dello workspace con cui interagiscono gli stakeholders. ParPlot è un toolbox di acceso libero disponibile nella pagina web GitHub. Ulteriori informazioni sull’utilizzo di ParPlot sono fornite come appendici.

Abstract
The aim of this thesis was to develop a methodology and a toolbox capable to support a negotiation process for an environmental multi-objective problem. The first part of this thesis focuses on the explanation of some of the existing Advance Visual Analytics, visual frameworks that are useful to discover innovative solutions to support stakeholders’ interaction with multidimensional data sets. Starting from solving a two-dimensional problem using the “Pareto Frontier” approach, then going through diverse techniques that can do representations of more than two dimensions. At the end of this part is done a comparison between the tools able to work with an environmental multi-objective problem data structure. The comparison gives as a result that the best technique is the Parallel Coordinates Plot, reason why ParPlot; a toolbox designed in this thesis, was developed based on this technique. The next part of the thesis presents a methodology developed for an effective use of ParPlot as a support in negotiation processes. Different steps have been identified, starting from the analysis of the data, up to the selection of the most feasible solutions, and finally to the presentation and sharing of the results obtained. After the development of the toolbox and the methodology, these were tested in a real case scenario. The case selected was the IMRR (Integrated and sustainable water Management) project on the Red-Thai Binh River basins, located in the north of Vietnam. The testing was done during a work session with three researchers acting as stakeholders, looking to analyze and select the best solutions according to their own objectives, arriving to a group of interesting solutions. The last part of the document is a description of the toolbox, from a technical point of view, and the workspace that stakeholders interact with. ParPlot is a free toolbox available in the webpage called GitHub. Further information about the use of ParPlot is provided as appendices.File | Dimensione | Formato | |
