Thanks Professor Apley !
Professor Daniel W. Apley is an Associate Professor at the Department of Industrial Engineering and Management Sciences at Northwestern University, IL. His research interests are in developing on-line methods for improving quality, reliability and maintainability in manufacturing (extended information available here).
Professor Apley gave a talk at the UW-Madison about:

Informs Conference in Denver,CO

Title: Variation Source Identification for Complex Manufacturing
Processes Based on Common Eigenspace
Abstract: This paper presented a data-driven variation source identification method
for complex manufacturing processes based on the analysis of the covariance matrix of
process quality measurements. The identification procedure utilizes the fact that the
eigenspace of the quality measurement covariance matrix can be decomposed into a subspace
due to variation sources and a subspace purely due to system noise. A testing procedure and
a case study are presented.

Title: Pattern Matching for Root Cause
Identification in Manufacturing Processes
Abstract: Root cause identification has drawn recent
attention in quality improvement. One widely used method is based
on pattern matching technique. The presence of unstructured noises
as well as sampling uncertainty will cause the fault symptom to deviate
from the fault signature. This paper developed a robust pattern matching
procedure considering both these effects simultaneously. The paper demonstrates
that the proposed method is robust and hence is a preferable tool for quality improvement.

Qualifying Examinations
Congratulations to PhD students Nong Jin and Zhiguo Li for passing their qualifying examination in manufacturing systems. PhD student Nong Jin is now officialy admitted into the PhD program of the Industrial and Systems Engineering department since he already passed his first examination in quality in January 2004.
Summer 2004
Camp Badger
This summer, our lab played a part in Camp Badger , which provides a mix of technological explorations, discussions, research, field trips and recreational activities to five one-week in-residence sessions with about 30 eighth grades in each session.
The mission of Camp Badger is to introduce WI youth of traditionally underserved populations to the engineering profession and the importance of math and science for their futures and showcase the UW-Madison campus and the College of Engineering.
Through the demonstration in our lab, we show the students how industrial engineers develop assembly lines and automation. In detail, they learned some basic knowledge about the goal and three key aspects of manufacturing together with their roles; also they got fundamental understanding of some different types of manufacturing. Finally they learned binary code programming and automation. All these knowledge will encourage the groups of kids to start thinking proactively about their future.
