Abstract—Ability to quick respond to customer demands has been a key competition factor in global market. Traditionally, product cycle time, work-in-process (WIP), order tardiness, and customer’ service levels are used to evaluate manufacturing systems’ performance. However, with rapid technology development toward Industry 4.0, these indices are not enough and unable to provide both prompt and detailed information regarding how congestion the system is. This study simulates a metal processing company where as taking into account a new measurement index about material flow, called flow value. With proper simulation experiments, DBR (Drum-Buffer-Rope) scheduling performs better than hybrid push/pull in most performance indices including flow value. A sensitivity analysis is also provided to show the robustness of DBR scheduling with respect to various demand patterns.
Index Terms—DBR, flow value, hybrid push/pull, simulation.
