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...

Selection of suitable sites for wind power plants is one of the most important decision on wind resources development. Site selection for the establishment of large wind power plants requires spatial evaluation taking technical, economic, and environmental considerations into account. This study has applied a combination of PROMETHEE and Fuzzy AHP methods in a geographical information system en...

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...

The Heterogeneous Wireless Network (HWN) integrates different wireless networks into one common network. The integrated networks often overlap coverage in the same wireless service areas, leading to the availability of a great variety of innovative services based on user demands in a costefficient manner. Joint Admission Control (JAC) handles all new or handoff service requests in the HWN. It c...

This paper applies a routing strategy based on Tarantula Mating Behavior as proposed by the authors, Bandyopadhyay and Bhattacharya [1], on a manufacturing network. The particular behavior which is of interest is that the female Tarantula spider sometimes eats the male Tarantula just after mating for satisfying immediate need for food or for genetic purpose. This interesting behavior has been s...

This paper presents an effective decision making framework for software selection in manufacturing industries using a multiple criteria decision making method, Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE). The method is improved in the present work by integrating with analytic hierarchy process (AHP) and the fuzzy logic. Fuzzy logic is introduced to handle the i...

Abstract In a portfolio selection problem, the first step is to choose suitable stocks at the right time. Many approaches and principles have been used to help investor solve the problem. This paper documents a new approach for the portfolio selection problem based on the combined method of Constrained Fuzzy Analytic Hierarchy Process (CFAHP) and the Preference Ranking Organization Method for E...

Eliciting the preferences of a decision maker is a crucial step when applying multi-criteria decision aid methods on real applications. Yet it remains an open research question, especially in the context of the Promethee methods. In this paper, we propose a bi-objective optimization model to tackle the preference elicitation problem. Its main advantage over the widely spread linear programming ...
