This paper proposes a method for stability-directed capacity requirements planning (CRP). The stability signifies here the sustainability of manufacturing systems and the predictability of CRP under the dynamic environment. In our CRP method, the probability of overload of each operation order is calculated, and then the starting times of operation orders are determined so as to minimize such overload probabilities. In computational experiments, the proposed method is compared with two conventional methods in terms of the machine utilization and the schedule stability. The experimental results demonstrate the effectiveness of the proposed method.
