Selection of appropriate supplier(s) for success of an organization is particularly a valuable necessity, hence apart from the common criteria such as logistics, service and quality, this paper discusses most of the key decision variables which can play a critical role in case of the supplier selection. In this study, analytic network process (ANP) method is used because it considers the relati...

Abstract: In this paper we improvise the work of Wang & Chen (2006) that used fuzzy numbers in the computation of consistent fuzzy preference relation (CFPR). Using the Herrera-Viedma et al. (2004) approach, we incorporate the centroid-index formula in constructing the evaluation matrices with fuzzy number elements. This will transform the fuzzy numbers into crisp values. The number of pair-wis...

most of the multi-criteria decision methods (mcdm), including analytic hierarchy process (ahp) and analytic network process (anp), use subjective judgments for obtaining the relative importance of the decision elements of a subject matter. this has been considered as one the important limitations of the mcdms. the f’anp model, a hybrid factor analysis and analytic network process (f’anp) model ...

ABSTRACT Global warming is the today’s important problem for all over the world. Due to the global warming, countries come face to face with lots of problems such as shortage of clean and usable water, erosion, usage of natural resources, and climatic problems. That’s why; in this paper, we proposed a model for selection of the utilization strategies for water resources in Turkey by using analy...

In the field of decision-making, the concept of priority is archetypal and how priorities are derived influence the choices one makes. Priorities should not only be unique but should also reflect the dominance of the order expressed in the judgments of pair wise comparison matrix. In addition, judgments are much more sensitive and responsive to small perturbations. They are highly related to th...

This study deals with prioritization of sustainable supply chin measurement indicators which are calculated by using Chang’s extent method of Fuzzy AHP. Within the model of Fuzzy AHP, main attributes, sub attributes and indicators are defined. The weights of them are calculated from the answers of questionnaire, which is formed for pair-wise comparison of attributes and indicators. The results ...

In this paper, deriving the fuzzy weights of criteria from the fuzzy pair-wise comparison matrix with triangular fuzzy elements is investigated. In the proposed method we first use the ranking function to convert the triangular fuzzy data into crisp one. Then by using the goal programming method we derive the fuzzy weights of criteria. We propose two new methods, and it is shown that these meth...

Droughts can be regarded as one of the most spatially complex geohazards, causing a severe impact on socio-economic aspects. Preparing comprehensive drought management plan is necessary to mitigate risks, and first step towards achieving it preparation vulnerability map. The present study integrates geospatial methods with Fuzzy-Analytical Hierarchy Process (Fuzzy-AHP) technique, prepare map fo...
