Tesis yeri seçimi ve tasarımı problemleri üzerine bir çalışma: Ev aletleri sektör uygulaması

Facility location selection and facility layout design decisions have strategic importance for companies since they influence not only manufacturing and transportation costs but also productivity and lead times to a great extent. Additionally, they are considered as hard and complicated tasks with respect to their multi-objective nature and difficulties resulted from collecting necessary data. Therefore these two problems have always been an important subject of industrial engineering literature. The aim of this study is to solve facility layout design and facility location selection problems consecutively in a manufacturing company that locates in Tekirdağ region of Turkey. This company has six different factories in the same facility in which one of them, namely consumer products factory has been recently established. In the first part of the application, by the help of excel-based software program CRAFT, new layout design alternatives were proposed to decrease material flow costs. As a part of the study, current situation was analyzed, from-to and transport cost charts were then presented and best layout solution is aimed to be defined iteratively by the help of CRAFT software. Additionally, the company is considering about establishing a plastic injection factory in the future for producing some of the important plastic components not only to gain cost advantage but also to increase know-how. For this purpose, in the second part of the application; facility location selection problem is aimed to be solved by applying fuzzy TOPSIS and fuzzy AHP methods and the results are compared to each other.
