Abstract: It is difficult to analyze the performance of customized manufacturing system with Automated Material Handling Unit (AMHU) by traditional open queuing network model with finite buffers. Focused on the random lot size of handling, a queuing network modeling method was put forward. Firstly, the system was described and the queuing network model was built. Secondly, the model of corresponding state space of each node was developed based on the improved state space decomposition method, and the performance further obtained. Finally, experiments to assess the effectiveness and the accuracy of the proposed method were reported by comparing the results with simulation. This study can provide a basis for further optimization on similar manufacturing system.

Key words: queuing network, AMHU (automated material handling unit), random lot size, Markov process, state space decomposition method
