Abstract: Facility location selection have strategic importance for companies because it influences not only manufacturing and transportation costs but also productivity and lead times to a great extend. Additionally, it is considered as hard and complicated tasks with respect to its multi-objective nature and difficulties resulted from collecting necessary data. Therefore this problem has always been an important subject of engineering literature. The aim of this study is to solve a facility location selection problem in a manufacturing company that locates in Tekirdağ/Turkey. This company has six different factories in the same facility and is considering about establishing a plastic injection factory in the future for producing some of the important plastic components in order to gain cost advantage and also to increase know-how. For this purpose, facility location selection problem is aimed to be solved by applying fuzzy data envelopment analysis (Fuzzy DEA) and fuzzy goal programming (Fuzzy GP) methods.
