In recent years, the Base Reinforcement System (BRS) has been developed and applied widely at building sites to improve the productivity of building operations and reduce the waste of materials. Because of customers' orders with a wide variety of specifications and very short delivery times, it is necessary to achieve e fficient production of foundation reinforcement units. In this study, we consider the practical production planning problem in a foundation reinforcement unit manufacturing factory, and propose a heuristic solution method to solve the mixed problem of materials' cutting plan decision and production scheduling. According to our computing experiment result, we can demonstrate that the method proposed in this paper can consider multiple orders simultaneously, decide the best cutting plan to improve the yield rate of materials, and meanwhile it can also obtain better production schedules with shorter makespan and less variation.
