Abstract

A flexible manufacturing system (FMS) enables the production of multiple-items with short production run. By using an automatic measurement system, it is possible to observe a large amount of items in a short time. The observations from the FMS include some variation patterns and outliers, thereby making it difficult to implement a conventional statistical process control. In this study, a retrospective analysis of such a process dataset is proposed. Our procedure detects multiple change points for a dataset with outliers and variation patterns such as shifts and trends. The locally weighted scatter plot smoothing and the jump/roof/valley detection procedure based on a local polynomial kernel smoothing are useful to develop our procedure. We modify these procedures and propose a robust procedure for detecting multiple change points.
