Abstract: Based on probability theory, queuing theory and renewal process theory, the model of the stochastic market demand for double product families and queuing control model for Reconfigurable Manufacturing Systems (RMS)were constructed. Taking production capacity and inventory of RMS as parameters, based on the reconfiguration cost, depreciation cost and storage cost of RMS, the average profit optimization model for a unit time was established. Optimization method and steps were proposed. The optimal production capacity and inventory of RMS were obtained by solving the model. According to the optimal capacity and inventory, the performance indexes of RMS, such as Acceptance Rate of Product Order(ARPO) and Change Cycles(CC) were provided. Finally, an example was used to illustrate the feasibility of the method.
