Abstract: Aiming at the problem that the factors of cycle time of mould production such as cellular structure of Job Shop,capacity of buffer and scheduling strategy could not be formulated by close forms,an approximate method based on regression statistics was proposed,which replaced the original constraints by approximate constraints and transformed the original problem to an approximate optimum problem.Through solving the optimum solution of approximate optimal configuration,the approximate solution of original problem was obtained.The simulation platform of dual-resource configuration was constructed,and the multiple line regression equation of average capacity and average production cycle constraints was acquired respectively by regression analysis based on the simulated data from the platform.The approximate optimum mathematical model was built by using the regression equation instead of these constraints that cannot be formulated by close forms.The optimal solution of the approximate optimum problem was obtained with integer linear programming method.The simulation experiment result showed that it was feasible to combine the use of simulation experiment and statistics analysis for this configuration of resources problem where some constraints could not be formulated by close forms.
