Abstract
Traceability is a crucial factor for the implementation of Industry 4.0, monitoring not only the location but also the status of products and assets enables intelligent manufacturing management. This study aims to evaluate systems to implement remote car traceability in a quality testing process. Firstly, opportunities for improving the traceability of cars through the quality testing process were assessed. Four enabling technologies were analyzed: radio frequency identification (RFID), Bluetooth low energy (BLE), LoRa and Ultra-Wideband (UWB), and a comparison based on five performance indexes, namely: cost, reliability, flexibility, quality and speed were performed. The quality process under study, which requires a traceability solution, was analyzed by sizing and characterizing the monitoring areas, raising all possible status of the cars and, finally, defining the solution requirements. Then, a study on the impacts that the possible implementation could have on the process of two policies to reduce the workforce dedicated to the activities and the related cost reductions. Still, a last stage of the project would consist of carrying out a proof of concept (POC), although it has not yet been carried out, this stage had some initial developments that will be exposed. Furthermore, this work addresses a discussion about the competition between new and established technologies. The main discussion revolves around the comparison between RFID and real-time location system (RTLS) technologies. The eligibility of the technology was based on the greater scope and the smallest addition of activities to its respective operation, with the cost of implementation and operation being a decisive factor. Real-time monitoring presents itself as the best solution for monitoring process failures. BLE technology stands out in said competition. It is noteworthy that the lessons learned during the process contributed to modifying the project planning.
