Abstract: To cope with infeasible production planning during the decision-making of integrated production plan owing to dynamic and stochastic production process, a decision－making model based on analytic-simulation feedback was put forward. For feasibility of analytic production decision-making model, dynamic simulation technology was used to describe real production system and feedback method was used to modify decision parameters. A feedback-based relaxation method for modify decision parameters was proposed. To revise stochastic decision-making parameters, an analysis model was constructed firstly, and its result was used in a simulation model to observe real production status. Then, the stochastic decision parameters were modified through comparison between the analysis model and simulation model. Continuously, the modified parameters were used to continue the process of analytic decision-making and dynamic simulation until the stop rule was satisfied. Algorithm convergence was proved by an example and decision-making effectiveness was proved by a case study.
