The invasion of new technologies combined with the high cost for running shop force enterprises to search for new sales methods. Network applications and ICT (Information and Communication Technology) can help achieve e-commerce goals. In Greece, many enterprises in the agro-food and drink sectors are already present on the internet. This paper studies the adoption of e-commerce on websites tha...

In this paper, the author presents the multi-criteria analysis methods, PROMETHEE I and II and GAIA, used for selecting the location of a nautical tourism port. In an example of the selected location of a nautical tourism port in the Northern Adriatic, the author has used an analytic and graphical evaluation for solving such a problem. Particular attention has been paid to the use of GAIA metho...

As the offshoring becomes more widespread, business practitioners outsource their activities to overseas countries. Although there is a wealth of academic literature examining outsourcing and offshoring, there is little literature that addresses the current outsourcing decision most firms facing, which is where to outsource. Given multi-attribute nature of offshore location selection, this pape...

This paper introduces the application of the multicriteria method Promethee II to the selection of a portfolio manager. Such application involves four main steps: (1) defining the list of potential actions or solutions to the problem; (2) defining the list of relevant criteria; (3) evaluating the performance of each action based on each criterion; and (4) aggregating these performances with the...

Robust Ordinal Regression (ROR) supports Multiple Criteria Decision Process by considering all sets of parameters of an assumed preference model, that are compatible with preference information elicited set of parameters, respectively. In this paper, we propose an extension of ELECTRE and PROMETHEE methods to the case of the hierarchy of criteria, which was never considered before. Then, we ada...

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...

In this paper we extend the PROMETHEE methods to the case of interacting criteria on a bipolar scale, introducing the bipolar PROMETHEE method based on the bipolar Choquet integral. In order to elicit parameters compatible with preference information provided by the Decision Maker (DM), we propose to apply the Robust Ordinal Regression (ROR). ROR takes into account simultaneously all the sets o...

Group decision is usually understood as the reduction of different individual preferences on a given set to a single collective preference. At present, there are few approaches which solve the group ranking problem with multiple criteria in a widely acceptable way. Often, they rest on a poor heuristic which makes a decision about consensus ranking difficult to support. This paper presents an ex...

This paper deals with the problem of ranking several alternatives on the basis of a valued preference relation. We present a system of axioms which is shown to characterize a ranking method based on the Min operator that has been introduced in the literature. IIntroduction In order to compare a number of alternatives taking into account several criteria, many aggregation methods (e.g. ELECTRE I...
