This paper focuses on the problem of supplier portfolio selection where a company has to choose best possible set suppliers with respect various constraints. An intuitive heuristic can suggest use any methods for ranking and then put first one into portfolio. If some required constraint is not met, second according added, so on, until all constraints are satisfied. However, such approach result...

The purpose of this paper is to help decision-makers choose the location a logistics platform with sustainability perspectives. This study presents compensatory and partially approach build composite indicators, using mainly fuzzy multi-criteria decision-making methods. In first instance, full consistency method (F-FUCOM) was used calculate weight criteria sub-criteria. second two aggregation m...

This article is based on previous author’s articles on a correct way for ranking alternatives in Multi-criteria Decision-Making (MCDM). A straightforward but robust Weighed-Sum Procedure (WSP) is presented. It consists in combining additively ranks or scores evaluated against a dimensionless scale, common to all criteria. MCDM methodologies based on pair-wise comparison methods are on the contr...

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...
