Many firms implemented various initiatives such as outsourced manufacturing which could make a supply chain (SC) more vulnerable to various types of disruptions. So managing risk has become a critical component of SC management. Different types of SC vulnerability management methodologies have been proposed for managing SC risk, most offer only point-based solutions that deal with a limited set...

Personnel evaluation is an important process in human resource management. The multicriteria nature and the presence of both qualitative and quantitative factors make it considerably more complex. In this study, a fuzzy hybrid multicriteria decision-making (MCDM) model is proposed to personnel evaluation. This model solves personnel evaluation problem in a fuzzy environment where both criteria ...

Rail transit systems, one of the important public transportation (PT) are widespread in large cities to satisfy passengers or commuters for their daily trips. However, rail (RT) investments costly, and budgets minimal. Thus assessing RT systems big play a crucial role deciding on best investment. In this study, first time, two-stage fuzzy set is used among multi-criteria decision-making (MCDM) ...

Today, due to the increase in people’s awareness of environmental issues and strict policies governments, competitiveness companies depends on considering at all levels supply chain. However, implementation green chain management strategies has lots different risks. The main contribution this research is evaluate rank tire industry with an emphasis risks sustainable using hybrid best-worst meth...

In a highly integrated ubiquitous wireless environment, the selection of a network that can fulfill end-users’ service requests while keeping their overall satisfaction at a high level, is vital. Thewrong selection can lead toundesirable conditions such as unsatisfiedusers,weak Quality of Service (QoS), network congestions, dropped and/or blocked calls, and wastage of valuable network resources...

Neutrosophic hesitant fuzzy set is the generalization of neutrosophic set and the hesitant fuzzy set, which can easily express the uncertain, incomplete and inconsistent information in cognitive activity, and the VIKOR (from Serbian:VIseKriterijumska Optimizacija I Kompromisno Resenje) method is an effective decision making tool which can select the optimal alternative by the maximum ‘‘group ut...

The fuzzy VIKOR method has been developed to solve fuzzy multicriteria problem with conflicting and noncommensurable (different units) criteria. This method solves problem in a fuzzy environment where both criteria and weights could be fuzzy sets. The triangular fuzzy numbers are used to handle imprecise numerical quantities. Fuzzy VIKOR is based on the aggregating fuzzy merit that represents d...

Plant location selection is a multi-criteria decision problem and has a strategic importance for many companies. The aim of this study is to propose a fuzzy approach for Plant location selection. This paper is based on a fuzzy VIKOR (Serbian: Vlsekriterijumsko Kompromisno Rangiranje) method. In this method, the ratings of various alternatives versus various subjective criteria and the weights o...

In this paper, we consider the problem of bus selection for public transportation using a hybrid multicriteria decision making approach. The problem includes several conflicting factors which are economic, social, and technological factors. The integrated approach brings the flexibility of fuzzy AHP and simplicity of fuzzy VIKOR methodology together. To demonstrate the applicability of the meth...

Most decision making problems can be considered as multiple criteria decision making (MCDM) problems, and should be solved by MCDM method. The main advantage of MCDM is that it can give managers many dimensions to consider related elements, and evaluate all possible options under variable degrees. This paper applied fuzzy set theory and a compromised MCDM method VIKOR method to evaluate the ser...
