论文摘要
现代统计过程监控（SPM）应用程序的重点是配置文件监视，即，可以将过程质量特征的监视可以模拟为概况，也称为功能数据。尽管对个人资料监视文献感兴趣，但仍然缺乏促进其实际应用的软件。本文介绍了Funcharts R软件包，该软件包实现了有关多元功能质量特征SPM的最新发展，可能会根据其他变量的影响（称为协变量）进行调整。该软件包还实现了所有控制图表过程的实时版本，以监视从中间域点的部分观察到的配置文件。该软件包通过其内置数据生成器和导航期间RO-Pax Ship CO2排放的SPM进行的真实研究进行了说明，该研究基于补充材料中提供的造船数据。
Modern statistical process monitoring (SPM) applications focus on profile monitoring, i.e., the monitoring of process quality characteristics that can be modeled as profiles, also known as functional data. Despite the large interest in the profile monitoring literature, there is still a lack of software to facilitate its practical application. This article introduces the funcharts R package that implements recent developments on the SPM of multivariate functional quality characteristics, possibly adjusted by the influence of additional variables, referred to as covariates. The package also implements the real-time version of all control charting procedures to monitor profiles partially observed up to an intermediate domain point. The package is illustrated both through its built-in data generator and a real-case study on the SPM of Ro-Pax ship CO2 emissions during navigation, which is based on the ShipNavigation data provided in the Supplementary Material.
