Purpose The purpose of this paper is to develop a stochastic multi-criteria decision-making approach to solute the warehouse location problem in the stochastic environment which contains uncertain condition. Design/methodology/approach In developed approach, the weight of criteria was calculated by using the stochastic analytic hierarchy process (SAHP) method. Alternative ranking was made and evaluated by fuzzy VIKOR (VlseKriterijumska Optimizacija I Kompromisno Resenje). Findings This study dealt with warehouse location selection problem of a supermarket that has sellers in many regions in Turkey and selected proper warehouse. Originality/value This study combined SAHP and fuzzy VIKOR methods as a solution approach for warehouse location selection problems.

It is clearly known that urban freight transportation has a significant role on sustainable development of urban areas. The persistent growth of the costs of freight transportation and as a result of congestion, environmental pollution and increasing inefficient usage of land in urban areas are forcing users and public authorities to develop alternative logistic solutions to relieve the freight traffic problem. Establishing logistics centers is one of these alternative solutions. Logistics centers are specific centers that various logistic based activities like distribution, storage, transportation, consolidation, handling, customs clearance, imports, exports, transit processes, infrastructural services, insurance, banking and similar commercial activities are performed. These centers are defined for national and international all logistic and related operations. Logistic centers must be settled near production and commercial centers, highways, railways, airports and if possible seaports. In this study we proposed a fuzzy TOPSIS approach to a logistics center location selection problem in eastern anatolia region of Turkey.

The correct choice of the devices used in the health sector is great importance for reduction of the workforce, improving quality and saving time. Therefore, selection of medical company that devices will be provided is an important decision problem. In this study, AHP and fuzzy VIKOR methods were utilized for selection of DNA-RNA-protein isolation device which will be used in a laboratory that conducts scientific research in the Atatürk University Faculty of Medicine. As a result of surveys conducted by responsible experts for the medical selection, 7 criteria were determined and pairwise comparison matrix has been established. Then, weights of criteria determined by AHP and 4 different alternatives were listed by fuzzy VIKOR. To the best of the authors' knowledge, there is no study on the selection of suppliers in the field of health in the literature. It is aimed to contribute to the literature in this respect.
