摘要
针对含物料自动运输环节(automated material handling unit,AMHU)的个性化定制生产系统性能分析问题,文章着重考虑其随机批量运输的特点,提出了该系统的开排队网建模方法。对含AMHU的生产系统进行了描述,并建立其排队网模型;采用改良状态空间分解法,建立了节点状态空间模型,求解并计算出生产系统的性能指标值;与生产系统仿真模型的实验结果进行对比,验证了所提方法的精确性和有效性,为进一步优化配置该类生产系统的资源奠定了基础。
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.
