Fuzzy AHP-TOPSIS Hybrid Method for Indoor Positioning Technology Selection for Shipyards

The shipyard industry, like other industries, is struggling to implement the principles of Industry 4.0 to shipyards in order to keep up with the challenges, and to realize Shipyard 4.0 in their own industry. Establishing a comprehensive positioning system to determine the positions of all living and non-living things in the shipyards and to follow their movements forms the basis of these studies. An advanced indoor positioning and tracking system can increase shipyards' efficiency, productivity and safety. SEDEF Shipyard, one of the largest shipbuilders in Turkey, is in a transformation to implement Shipyard 4.0 and to keep up with the challenges. In this context, this article primarily provides a comprehensive analysis of the shipyard environment. From this analysis, the basic hardware and software technical requirements regarding which indoor positioning system would be more suitable for shipyards are determined. Next, an integrated evaluation model is developed with a fuzzy AHP and fuzzy TOPSIS for the selection of positioning technology that allows the delivery of advanced services at the SEDEF shipyard. With the model, it is aimed to determine the most suitable technology for SEDEF shipyard by evaluating different technology options.
