Combining Blockchain with an E-Kanban System for Pull Leveling of an Assembly Line

Kanban system is a tool of the Just-in-time approach that many automotive companies have been adopted to improve their in-house operations. However, the traditional Kanban system has experienced some disadvantages in meeting the performance targets in terms of inventory, delivery, quality, and cost. In this paper, we propose a new combination approach of Blockchain and Electronic Kanban (E-Kanban) system to improve the traditional Kanban system for pull leveling pattern associated with the parallel information system. The proposed system is simulated to validate the feasible solutions for continuous improvement purpose. A real case of a leading automotive company in Vietnam is investigated to illustrate the proposed system.
