Course Introduction:

In today’s competitive business environments, companies have urgent needs to use advanced analytical tools to manage their industrial data to gain more insights of their operations. Those insights include machine health condition, system remaining useful life, system performance, and other key performance indicators. With the advent of networked devices, an abundance of data now exists in virtually every level of industry, from the individual manufacturing asset to the manufacturing facility as well as the entire organization. This data is often not used to its greatest potential. It is often acquired, stored and forgotten. Most organizations understand the need for acquiring data, but do not understand how to leverage the data to enhance their system design, condition monitoring and decision-making capabilities. This course will introduce students to advanced technologies—such as prognostics and health management (PHM), intelligent networks, and smart machine systems, and intelligent maintenance systems—that ultimately enable the conversion of industrial big data into actionable information that can be used to improve the design, the productivity and the efficiency of manufacturing operations.

Students will learn to utilize intelligent tools for converting big data to information with a focus on monitoring, assessing, predicting and diagnosing the condition of industrial assets. These tools will be used in conjunction with advanced platforms for intelligent system design and implementation. Students will follow a proven systematic process, which includes instrumentation, experimentation, data acquisition and data analysis. Students will be divided into groups to conduct term-project in applying this process for industrial big data applications.

Midterm & Final:

One midterm quiz will be given during the semester. No make-up exams will be given unless students have an emergency or made pre-arrangement with instructor. Unless otherwise noted, all tests will be closed book and closed notes. All students need to do a term-project in the e-Manufacturing lab and submit the report for final grade.


Homework will be assigned and collected on a regular basis. All homework problems or sets will be graded in detail. Due date will be announced at the time when the homework is assigned. No late homework is accepted except under extenuating circumstances as determined by the instructor.

Course project:

Students will be divided into groups to finished course projects. The course projects are all industrial big data analysis related topics. The course projects requires students to use analytical tools learned from this course to deal with real problems and which is also not limited to only use what you learned here. Innovative solutions and ideas are encouraged by bonus points.


Students are expected to attend all classes (please be on time). Even though most of the course materials are well covered by the posted lecture notes and text, there may be some information that is discussed exclusively in class. If you missed class, you are still responsible for learning the materials taught during your absence.


Assignments and course content are subject to modification when circumstances or sound pedagogy dictate and as the course progresses. If changes are made, you will be given due notice.

Academic Integrity:

The University Rules, including the Student Code of Conduct, and other documented policies of the department, college and university related to academic integrity will be enforced. Any violation of these regulations, including acts of plagiarism or cheating, will be dealt with on an individual basis according to the severity of the misconduct.

Final Project Report Due




Assignment #1:

• The important publications, government reports, and white papers are made available to the students.

• Survey the literature to get an understanding of Industrial 4.0, digital transformation in manufacturing, cyber-physical systems.

• Develop a survey report and a 5-minute presentation to share their vision with the class.

• The homework will be finished by individual student.

Assignment #2:

• A bearing vibration dataset and specific homework requirements will be given to the student. The dataset is generated from the vibration test in the IMS center.

• Sample code for Fast Fourier Transform and logistic regression will be provided to the student to finish the homework.

• The student will have to finish the homework through collaboration with other group members.

• Each group must prepare a 5-minute presentation to present their work in the class.

Assignment #3:

• The students are asked to use the Self-Organizing Map (SOM) and SOM-MQE to detect and diagnose the bearing failure. Sample code for SOM and SOM-MQE will be provided to the class to finish the homework.

• The assignment will be finished by the group, and each group is asked to report their work in the class through a 5-minute presentation.

Assignment #4:

• Students are asked to use the Support Vector Machine (SVM) and other algorithms to detect and diagnose the bearing failures. Sample code for SVM will be provided.

• The assignment will be finished by the group, and each group is asked to report their work in the class through a 5-minute presentation.

Invited Speakers:

The class will invite three speakers from the industry to share their strategic vision about industry 4.0, smart manufacturing, and other advanced topics in manufacturing. In the past, the speakers from IMS member companies, e.g. Taiwan Semiconductor Manufacturing Company, Protector & Gamble, Mazak, Hitachi, Predictronics, were invited to speak in the class. These invited speakers will give a one-hour lecture in the class.

Invited Lecture Session:

The class also has lecture sessions about the Internet of Things, Deep Learning and advanced analytics, cybersecurity in manufacturing. These sessions will be delivered either by IMS


Final Projects:

Project 1: Fault detection in semiconductor Etching

Project 2: Gearbox fault diagnosis and prognosis

Project 3: Bearing fault diagnosis and prognosis.

Project 4: Virtual metrology for critical semiconductor manufacturing processes

Project 5: Machine tool degradation prognosis and remaining useful life prediction.

Project 6: Aero-engine remaining useful life prediction

In the final project, each student group will focus on one of the 6 projects that are listed above. The dataset and detailed requirements will be given to students to start the project. TA will be assigned to each group to provide support and answer questions. Each group will work independently to fulfill the requirements in the final project. In the exam week, each group will make a 15-minute presentation to report their work and document all the details in a report. When promising results are achieved or novel methods are proposed, the instructor will advise the student group to publish papers at conferences or research journals.

The concept of design these projects is to motivate students to learn by address real-world problems independently. The datasets used in these final projects are from IMS past research projects or open data competitions. They are all real-world datasets generated from machines or production lines. Although each student group will focus on one of the 6 projects in this class, the datasets of all these projects will be made accessible to all the students for their future use.
