中文简介:
在制造业中,黄金批次是生产所需物品的完美过程的理想化实现,通常表示为压力,温度,流速等多维时间序列。黄金批次有时由第一原理模型生产,但它通常是通过记录由最有经验的工程师在仔细清洁和校准的机器上生产的批次而创建的。在大多数情况下,黄金批次仅用于对质量出乎意料的低劣产品的事后分析,因为工厂经理试图了解最后一次生产尝试在何时何地出错。在这项工作中,我们为黄金批处理做出了两个贡献。我们引入了一种在线算法,允许从业者实时了解该过程当前是否偏离黄金批次,从而允许工程师进行干预并可能保存批次。例如,可以通过冷却意外运行的锅炉来完成。此外,我们表明,我们的想法可以大大扩展黄金批次监控的范围,超越工业制造。特别是,我们表明,黄金批次监控可用于许多新领域的异常检测,注意力集中和个性化培训/技能评估。
课程简介: In manufacturing, a golden batch is an idealized realization of the perfect process to produce the desired item, typically represented as a multidimensional time series of pressures, temperatures, flow-rates and so forth. The golden batch is sometimes produced from first-principle models, but it is typically created by recording a batch produced by the most experienced engineers on carefully cleaned and calibrated machines. In most cases, the golden batch is only used in post-mortem analysis of a product with an unexpectedly inferior quality, as plant managers attempt to understand where and when the last production attempt went wrong. In this work, we make two contributions to golden batch processing. We introduce an online algorithm that allows practitioners to understand if the process is currently deviating from the golden batch in real-time, allowing engineers to intervene and potentially save the batch. This may be done, for example, by cooling a boiler that is running unexpectedly hot. In addition, we show that our ideas can greatly expand the purview of golden batch monitoring beyond industrial manufacturing. In particular, we show that golden batch monitoring can be used for anomaly detection, attention focusing, and personalized training/skill assessment in a host of novel domains.
