  3. Abstract: Supply chain scheduling (SCS) is the process of making a plan such that the products are produced and distributed to the right location, and at the right time with the minimum cost. Traditionally centralised SCS models have been developed and used in industry. However, due to the polynomial computational complexity, it is often not practical to find an optimal solution but to search a merely feasible solution with some simplification processes. This research proposes an innovative decentralised SCS approach using supervisory discrete-event system which guarantees the optimal solution rather than a feasible solution. The optimal solution obtained will provide great cost/time savings with the simplified scheduling process in various industries.
