Managing variations in process control: An overview of sources and degradation methods

Abstract

Understanding variation is a crucial aspect of managing and improving any manufacturing or product development process. This paper investigates sources of variations in process control. It shows main sources of variability such as actual process variations or measurement variations. Moreover, it attempt to classify causes of variation. Based on state-of-the-art research methods, researchers are able to investigate variability and develop a process to minimize the negative impact of variability on processes. In particular attention is the role of human factors and its diverse impact on process control.
