Robustness analysis and visualization are two of key concepts of multi-criteria decision support. They enable the decision-maker to improve his understanding of both the model and the problem domain. A class of original mathematical optimization based robustness metrics is hence defined in this paper. In addition, several efficient existing techniques that have been successfully used in various...

In this paper, alternate schemes are examined and analysed aiming at the improvement of MSW management in small urban municipalities in Morocco. These schemes are estimated by developing and applying the PROMETHEE method consisting in a multi-criteria analysis of the parameters and the constraints bound to the financial, technical, environmental and social-institutional aspects. Thus, 10 altern...

Ziel der vorliegenden Arbeit war es, ein Konzept zur Bewertung von Temperaturüberwachungssystemen zu entwickeln. Insbesondere galt es, deren unterschiedliche Potenziale zur Verbesserung des Kühlkettenmanagements in Fleisch erzeugenden Ketten darzustellen und zu rangieren. Die Grundlage der Konzeptentwicklung bildeten mehrere empirische und experimentelle Studien. Die Charakterisierung von Schlü...

supplier selection is a multi-criteria problem. this study proposes a hybrid model for supporting the suppliers’ selection and ranking. this research is a two-stage model designed to fully rank the suppliers where each supplier has multiple inputs and outputs. first, the supplier evaluation problem is formulated by data envelopment analysis (dea), since the regarded decision deals with uncertai...

in this study, an outsourcer evaluation and management system is developed for a manufacturing company by use of fuzzy goal programming (fgp). a first phase of the methodology evaluation criteria for outsources and the objectives of the company are determined. considering the fuzziness in the decision data, linguistic variables that can be expressed in generalized fuzzy number are used. the pro...

As threshold determination is arduous when using PROMETHEE (Preference Ranking Organization METHod for Enrichment Evaluations) to make decisions, this study proposes a comprehensive PROMETHEE-based group decision support covering the uncertainties of determination, risk preferences, and evaluation itself. To reduce difficulty on it explicitly offers statistical aggregation individuals’ indiffer...
