Abstract: The facility capacity configuration optimization of order-driven equipment's manufacturing system belongs to nonlinear integer programming problem.Owing to the reasons that the throughput and flow time constrains could not be described by closed form,an approximate optimization method of approaching the optimal value of objective function by its upper and lower bound was proposed.The capacity configuration of order-driven equipment's manufacturing system was described,and the mathematical model was developed with the object of minimum facility cost.The composition of approximate optimization method integrated mathematical analysis with simulation optimization was introduced.The process of acquiring the initial value's upper and lower bound and approaching to the optimal value of objective function was presented in detail.The proposed method was verified by the case study,and the results were compared with the situation of throughput single constrain.The analysis showed that the proposed method could provide decision support for optimization allocation of enterprises resource.
