- A cooperative multicriteria group decision aiding tool: a guide tour of the desktop applicationPublication . Fernandes, Sérgio; Clímaco, João; Captivo, Maria EugéniaThe main features of the adaptation to a face-to-face cooperative group approach of an interactive decision support tool previously developed with the aim of supporting decisions concerning multicriteria location problems are described. In the application implemented there is no inter-criterion aggregation, so there is no need to reduce the various evaluation dimensions into the same scale. It allows for the individual intervention of several elements of the group, includes some logical tools as well as the possibility of introducing constraints. Furthermore, it propitiates an extensive use of interactive graphics. A guided tour of the desktop application emphasizing its potentialities and limitations is presented.
- A Discussion on the Role of Decision Support in a Location Analysis Case StudyPublication . Clímaco, João; Fernandes, Sérgio; Captivo, Maria EugéniaIn this paper, we discuss a case study regarding transfer stations siting in a Solid Waste Management System, building a multi-criteria model potentially adequate to the involvement of multiple actors. A Decision Support System (DSS), named SABILOC ([1]), integrating an Interactive Bi-objective Integer Programming Module and a Multi-attribute Module is used. The last module allows an a posteriori more detailed analysis of the solutions selected during the first module. Furthermore, the DSS includes meaningful graphical tools and integrates a Geographic Information System (GIS).
- A DSS for Bicriteria Location ProblemsPublication . Fernandes, Sérgio; Captivo, Maria Eugénia; Clímaco, JoãoIn this paper, we present a new interactive decision support system (DSS) – named SABILOC – in action. The DSS is aimed at supporting decision-making concerning bicriteria location models and it was specially designed to deal with problems in which the facilities to be located have environmental impacts. We point out three advantages of SABILOC when compared with other DSS for location problems available in the literature. Firstly, an interactive procedure is used allowing the decision-maker to obtain non-dominated solutions for bicriteria location models. Secondly, a multiattribute analysis module allows the decision-maker to proceed with a more detailed analysis of a subset of solutions selected from the first interactive phase. Finally, the embedment of a Geographic Information System into SABILOC makes the system much more useful in real world location problems. In order to better describe and validate the potentialities and functionalities of SABILOC, we present a case study of a real world problem applied to waste transfer station siting.
