Implementation of an RFID-Based Sequencing-Error-Proofing System for Automotive Manufacturing Logistics

Abstract

Abstract:Serialized tracing provides the ability to track and trace the lifecycle of the products and parts. Unlike barcodes, Radio frequency identification (RFID), which is an important building block for internet of things (IoT), does not require a line of sight and has the advantages of recognizing many objects simultaneously and rapidly, and storing more information than barcodes. Therefore, RFID has been used in a variety of application domains such as logistics, distributions, and manufacturing, significantly improving traceability and process efficiency. In this study, we applied RFID to improve the just-in-sequence operation of an automotive inbound logistics process. First, we implemented an RFID-based visibility system for real-time traceability and control of part supply from the production lines of suppliers to the assembly line of a car manufacturer. Second, we developed an RFID-based sequence-error proofing system to avoid accidental line stops due to incorrect part sequencing. The whole system has been successfully installed in a rear-axle inbound logistics process of GM Korea. We achieved a significant amount of cost savings, especially due to the prevention of sequencing errors and part shortages, and the reduction of manual operations. Thorough cost-benefit analysis demonstrates the clear economic feasibility of using RFID technologies for the just-in-sequence inbound logistics in an automobile manufacturing environment.

Understanding the purchasing portfolio model: A just-in-sequence approach increasing manufacturing efficiency

“…Design of Just-in-sequence is researched from the view of supply chain solutions. Just-in-sequence supply include several advantages of the manufacturing and supplier processes in the followings: automotive industry has been encouraged for the following tasks [15]: to enabling the smallest lot numbers to be produced at a minimal stock level [16], supermarkets and decentralized logistic areas [17], improving the just-in-sequence operation of an au-tomotive inbound logistic process [18] and services by applying RFID [19]. The systems work smoothly better and provides comprehensive assurance in the installation of the wiring harnesses [20].…”

Termék-azonosítási problémák kezelése Ipar 4.0 technológiák használatával

“…Érdekes alkalmazások találhatók az oktatás, a logisztika, a személyszállítás [13] vagy az állatok intelligens logisztikai irányítása [14] területén. Az RFIDalapú szekvencia-hibabiztos rendszer bevezetése az autóipar logisztikájához megmutatja ennek a technológiának a minőséggel kapcsolatos folyamatokra gyakorolt hatását, mint például a teljes minőségirányítás, a termékek és a folyamatok minősége [15].…”

False Positive RFID Detection Using Classification Models

“…Radio frequency identification (RFID) is a key Industry 4.0 enabling technology, and has been widely used throughout manufacturing and supply chains. RFID transfers data between readers and movable tagged objects and has been applied to many diverse areas, including tracking and managing assets in healthcare [2][3][4], reducing misplaced inventory throughout supply chains [5], measuring soil erosion [6], and improving just-in-time operation for automotive logistics [7]. The technology has also provided significant advantages for bee monitoring [8], tracking ship pipes [9], customer purchase behavior analysis [10], inventory management [11], indoor robot patrol [12], etc.…”
