Thai dessert production process is recognized as a very complicated process which contains many constraints. Generally, this process is classified as a job shop production. The selected factory has operated for more than 30 years. Furthermore, over 30 types of Thai dessert are produced. The major problem found relates with a current production planning process which strongly relies on planner’s experience. This planning method results in a relatively high makespan, which also causes a high production cost. The main objective of this research is to design a production planning process corresponding to a major characteristics and constraints of the selected factory. Moreover, this planning process is a combination and modification of many dispatching rules. To prove a performance of the designed production planning process, an experiment is conducted based on real demand data of the selected factory. A result of the experiment shows that the designed planning process can reduce a makespan by 113 minutes or 12.18% comparing with factory method. Additionally, this planning process can help long-processing time job to start earlier.
