In this research, we revised and extended the mathematical model that was developed by Herer and Masin (1997), the modified model can be applied for push and pull systems into integrating scheduling and sequencing problems. This model tried to inherit the benefits of both pure push (MRP systems) and pure pull (JIT systems). As the model is modified for Vietnamese companies, this research will support the production managers for their efficient production planning. By providing good solutions quickly, this model is very useful for production managers to adjust their scheduling and sequencing. However, this model is very complex, and takes time to solve. Therefore, Tabu search algorithm was employed for finding solutions.
