Value Stream Mapping-based Logistics 4.0 Readiness for Thailand Automotive-Part Manufacturers

The automotive industry in Thailand have competed fiercely, especially second-tier and third-tier automotive part manufacturers. They are hence impelled to apply technology 4.0 (i.e. robots, automation, and internet of thing). The technology 4.0 application is however achieved when logistics activities are leaned along their value streams. The lean logistics aims to add more values using value stream mapping (VSM). It supports to visualize a current state map of logistics activities along their value stream. The current state map facilitates to analyze the most critical problems having the highest non-value added. They are then overcome with suitable solutions whereas a future state map is drawn. In an industrial case, the most critical activities are case, disc, and cover lathing and washing; and heating respectively. They are replaced by technology 4.0 i.e. robot arms, induction machines, and conveyors in order to shorten cycle time and lead time. They lead to increase value-added ratio.
