In Multi-criteria Decision Making (MCDM) problems dealing with qualitative criteria and uncertain information the use of linguistic values is suitable for the experts in order to express their judgments. It is common that the group of experts involved in such problems have different degrees of knowledge about the criteria, so we propose a multi-granular linguistic framework such that each exper...

It is generally believed that the preference ranking method PROMETHEE has a quadratic time complexity. In this paper, however, we present an exact algorithm that computes PROMETHEE’s net flow scores in time O(qn log(n)), where q represents the number of criteria and n the number of alternatives. The method is based on first sorting the alternatives after which the unicriterion flow scores of al...

1.1 Agile Development The Agile Manifesto explicitly states that priority should be given to ‘‘individuals and interaction over processes and tools, customer collaboration over contract negotiation, working software over comprehensive documentation, and responding to changes over following a plan’’ [1]. Thus these agile principles promotes the flexibility by allowing changes to project requirem...

Emergency department has become a useful way to the access to hospital and it is a subject of study for many researchers. The research developed in this paper aims to improve the performance of the emergency department(ED) of Sfax Hospital. Simulation results showed that to manage to increase the number of treated patients and thus to decrease the patient cycle time, it is important to add a sp...

New energy storage alternative selection is a hot research issue that involves multiple-criteria decision-making process. In view of the existing deficiencies of multiple-criteria decision-making methods, an optimized method of PROMETHEE was proposed based on interval neutrosophic sets that has the advantage in describing fuzzy decision-making information. Robustness evaluation was conducted to...

The purpose of multicriteria clustering is to locate groups alternatives that have comparable qualities and been examined across multiple criteria. An ordered profile a well-known problem, the fuzzy c-means (FCM) technique one most broadly used in every field life. At present, FCM for partitioning information into numerous clusters which are still lacking priority relations. To address problem ...

PROMETHEE and GAIA belong to the family of multi-criteria outranking methods. A key aspect of their successful application to real problems relies on the existence of user-friendly software implementing these approaches. Following PROMCALC and DECISION LAB 2000, D-Sight is the third generation of PROMETHEE and GAIA based applications. It offers multiple interactive and visual tools that help th...

The paper proposed a linguistic PROMETHEE approach for making investment portfolio decision. First, we both consider quantitative and qualitative information of each stock and use 2-tuple linguistic value for experts to express their opinions to obtain qualitative information with respect to all evaluation criteria. Then, the transformation method of 2-tuple linguistic variable is applied to ag...
