A dynamic optimization production method is a focused approach to planning and continuous improvement for all operations and processes in the distribution center. A mathematical model is developed and presented to solve the optimal control problem in matching multi-stages production plan at any point in time. The main purpose is to investigate the optimal choice between production rate and the optimal production plan at each time through different strategies so as to achieve due date. This method provides a way for decision makers to attend to the best starting point for any given time point w...
