Towards unsupervised measurement of assembly work cycle time by using wearable sensor

This paper presents a new method for monitoring and managing factory workers of assembly works by using a wearable sensors. In line production systems, a worker repetitively performs predefined operation processes. Since the delay of a worker's process influences the entire line production system, measuring and managing cycle time of each worker's operation process is important. This study tries to measure cycle time of a worker using a wearable sensor in unsupervised manner.
