In today's competitive and high technology world, companies are forced to differentiate themselves with continuous improvement. They need creative, well-educated and self-confident human resource more than ever. Hiring the right person to the right job plays a significant role on firm's growth. The goal of this paper is to propose a systematic approach for personnel selection problem (PSP) of a textile company in Turkey by considering various performance requirements and criteria. The proposed framework consists of three phases. Initially, Fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL) method is used for weighting social criteria. Then, weights of technical requirements are calculated by applying Fuzzy Quality Function Deployment (QFD) method allowing to evaluate the interrelationships and correlation of social and technical criteria. Finally, Fuzzy Grey Relational Analysis (GRA) method has been applied to rank the alternatives by considering criteria scores acquired in the previous phase. The method has been illustrated by a case study and compared to the current approach used in the company. The results indicate that this proposed approach can deal with the PSP effectively and help companies to establish a systematic and unbiased way for the problem.

Today's environmental conscious world forces companies to be more concerned with energy and water consumption. New trends in the world generally provide competitive advantage to the firms if they work on environmental issues. As a critical decision of companies, supplier selection problem needs to consider the environmental factors and economic factors simultaneously. This study proposes a novel solution methodology for green supplier selection problem: Fuzzy axiomatic design with risk factors.This method is applied in many decision-making problems in the literature successfully. A case study is presented to implement the method and the results are compared with traditional fuzzy axiomatic design and fuzzy TOPSIS. It has seen that the decision of the best supplier selection can be influenced by the risk factors such as the deviation in the economical conditions or the working conditions of the company.
