        abstract = {Baggage handling breaks airports faster than almost anything else on the ground. A single peak-hour sorting failure cascades into delayed flights, missed connections, and compensation claims that stack up quickly. Manual sorting can't keep pace with modern passenger volumes it’s slow, error-prone, and collapses under pressure. This paper proposes an automated baggage carrier system built around PLC control and sensor-driven conveyor mechanisms. The system runs photoelectric sensors, barcode and RFID identification modules, and motorized diverters under a ladder logic program that makes every routing decision in under a millisecond. The entire control architecture was built in Siemens TIA Portal and tested inside Factory I/O's real-time simulation environment, where the PLC ran against a physics-accurate virtual conveyor without knowing the difference. Sorting accuracy improved, manual intervention dropped, and the design held up under concurrent baggage loads without a single misroute.},
