Abstract

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.

函数图:R中用于多变量函数数据的控制图
现代统计过程监控(SPM)应用侧重于概要监控,即对可以建模为概要的过程质量特征的监控,也称为功能数据。尽管对剖面监测文献有很大的兴趣,但仍然缺乏促进其实际应用的软件。本文介绍了funcharts R包,它实现了多变量函数质量特征的SPM的最新发展,可能会受到附加变量(称为协变量)的影响进行调整。该包还实现了所有控制图表程序的实时版本,以监视部分观察到的配置文件,直至中间域点。该软件包通过其内置的数据生成器和基于补充材料中提供的船舶导航数据的Ro-Pax船舶航行期间二氧化碳排放SPM的实际案例研究进行了说明。
