Integrated Model of Problem Structuring and Multicriteria Group Decision Making for Social Sustainable Development
Keywords: Soft System Methodology, Multicriteria, Sustainable development, Soft and Hard OR, Group Decision.
AbstractMany social decisions in the real world are characterized by deepcomplexity, not only in terms of economic aspects, but also dealing withsustainability policy problems. Indeed, the emphasis to find a solution byrepresenting the situation and its relationships in a decision problem onlymathematically, focused simply in restricts views, is not enough. Nowadays, tomake a social decision is imperative to promote a group discussion to find asustainable solution and to input more emotional arguments into the problem.However, although there are several methods of problem structuring (soft OR)and methods to evaluate the problem (hard OR), there are still few worksdealing with the integration of these two approaches. This paper proposes agroup decision model, integrating tools of problem structuring and multicriteriaevaluation. The problem structuring approach is used to facilitate and to shareinformation starting from the participative development, as a way to generatealternative ideas of solution and to improve the learning process among all theinvolved members. The multicriteria evaluation is used to find a global solutionfor the problem, incorporating the points of view of all members involved in thedecision process. The purpose of this model is to generate a richer and moreeffective way of handling the problem situation.
