摘要

摘要应用自组织临界性理论分析了复杂制造系统的非计划停机时间(USDT)特征。通过Hurst指数值验证了USDT序列的长程相关性。然后，我们利用极值理论建立了频率与USDT持续时间的关系模型。模型参数采用极大似然法估计，当有新数据时采用贝叶斯推理进行更新。最后，通过半导体组装测试厂瓶颈系统的USDT数据验证了所提方法的有效性。

Self-organized criticality in manufacturing system unscheduled downtime series and its application to major failure prediction

Abstract In this study, self-organized criticality theory was applied to analyze the unscheduled downtime (USDT) characteristic of a complex manufacturing system. The long-range correlation of the USDT series was verified through the Hurst exponent value. Then, we developed a model to depict the relationship between the frequency and USDT duration with the extreme value theory. The parameters of the model were estimated with the maximum likelihood method and updated with Bayesian inference when new data was available. Finally, the effectiveness of the proposed method was validated by the USDT data of the bottleneck system from a semiconductor assembly and test factory.
