In-situ Quality Assurance via Multi-Sensor Data Fusion

 

报告人 Judy Jin

Department of Industrial and Operations Engineering

Director of Manufacturing Program, University of Michigan

 

报告内容摘要：

Connected manufacturing systems with distributed in-situ process sensing provides the feasibility to acquire and communicate massive process operational data during production.  This provides unprecedented opportunities for in-situ quality control for defects prevention. Meanwhile, it also calls for data analytics challenges for modeling the intricate dependency of products quality on massive in-situ sensing signals. This research aims to develop a general functional regression model for predicting a scalar quality response based on mixed types of process sensing data including images and functional waveform signals as well as scalar process setup parameters. To represent a set of time-dependent images, a third-order tensor is taken with the advantage of preserving not only the spatial correlation within one image but also the temporal dependency among multiple images. Simulation studies and a case study will be presented to discuss the proposed iterative estimation method and model inference.

Data Science in Autonomous Experimentation Platform

 

报告人 Yu Ding

Mike and Sugar Barnes Professor of Industrial & Systems Engineering

Texas A&M University

 

报告内容摘要：

In 2016, US Air Force Office of Scientific Research issued a MURI call for developing autonomous material experimentation platform, a smart manufacturing system that can look for new materials on its own, with no or minimum human intervention. A group of faculty members at Texas A&M University responded, made to the final round of five full proposals, but in the end failed to win the competition. This failed MURI effort, on the other hand, catalyzed a strong interest and subsequent collaboration among data scientists and material scientists, which is still ongoing. In the ensuing years, the team had better lucks with other opportunities and is in fact actively researching for a solution related to the original AFOSR’s call.  In this talk, the speaker would like to share his thoughts concerning the challenges and possibilities for such an autonomous experimentation platform.

A Convolution Framework for Learning and Predicting

3D Printing Shape Accuracy

 

报告人 Qiang Huang

Department of Industrial and Systems Engineering

University of Southern California

 

报告内容摘要：

Geometric shape accuracy is an important quality measure for products built by additive manufacturing (AM) processes. With increased availability of AM product data and advances in computing, Machine Learning for AM (ML4AM) has become a viable strategy for enhancing printing performance. We propose a Shape Deviation Generator (SDG) under a novel convolution formulation to facilitate the learning and prediction of 3D printing accuracy. Shape deviation representation, individual layer input function and transfer function for the convolution formulation are proposed and derived. A deconvolution problem for identifying the convolution kernel is formulated to captures the inter-layer interaction effects in the layer-by-layer fabrication processes. The printed 2D and 3D shapes via a stereolithography (SLA) process are used to demonstrate the proposed modeling framework and derive new process insights for AM processes.

Data Science in Precision Medicine of Brain Diseases: Bridging to Monitoring, Diagnosis, and Treatment

 

报告人 Jing Li

School of Computing, Informatics, and Decision Systems Engineering

Arizona State University

 

报告内容摘要：

The brain is the most complex organ of the human body. The booming of artificial intelligence was originally motivated by attempting to mimic how the human brain works in problem solving. As much as one can be amazed by how the brain works in healthy individuals, the brain is susceptible to various types of diseases that are extremely difficult to treat – largely due to our lack of understanding of this complex organ. Examples of these diseases include, but not limited to, glioblastoma – an aggressive type of cancer with median survival of only 14 months, Alzheimer’s Disease – currently no cure, migraine – affecting 1 out of 4 U.S. households, traumatic brain injury – contributing to a third of all injury-related deaths, etc.

Just like the rest of the world that is being dramatically changed at the availability of immense amounts of data, medicine is facing enormous challenges of effectively transforming various forms of data into information and ultimately into decisions to revolutionize patient care. In this talk, I will present some unique data science challenges and our attempts in the solution methodologies for providing enabling tools in monitoring, diagnosis, and treatment of brain cancer and diseases.

Detecting Bursts in Water Distribution Systems with

Functional Data Analysis

 

报告人 Jian Liu

Department of Systems & Industrial Engineering

University of Arizona

 

报告内容摘要：

Bursts in water distribution systems (WDSs) are a special type of short-term, high-flow water loss. Since WDSs are usually deployed underground, it is difficult to detect bursts before their catastrophic results being observed on the ground surface. Continuous hydraulic data streams collected from automatic meter reading and advanced metering infrastructure systems make it possible to detect bursts in WDS based on data analytics. Conventional statistical process control methods may not be effective. This is because that the temporal correlations and non-stationary shifts imbedded in the data streams are not explicitly considered, leading to high rate of false alarm and/or miss detection. In this research, a burst detection method based on functional data analysis is proposed. The temporal correlations are modeled with functional bases, and the non-stationary shifts induced by bursts are decomposed as anomalies from the data streams of customers’ daily use without bursts. The proposed method significantly reduces the rate of false alarm or miss detection. Its effectiveness is demonstrated with a case study based on numerical simulation of a real-world WDS.

Multisensor Degradation Modeling and Prognostics

 

报告人 Kaibo Liu

Department of Industrial and Systems Engineering, UW-Madison

Associate Director, UW-Madison IoT Systems Research Center

 

报告内容摘要：

In condition monitoring, multiple sensors have been widely used to simultaneously collect measurements from the same unit to estimate the degradation status and predict the remaining useful life. In this talk, we propose a generic framework for multisensor degradation modeling, which can be viewed as an extension of the degradation models from one-dimensional space to multi-dimensional space. Specifically, we model each sensor signal based on random-effect models and characterize failure events by a multi-dimensional failure surface which is an extension of the conventional definition of the failure threshold for a single sensor signal. To overcome the challenges in estimating the failure surface, we transform the degradation modeling problem into a supervised classification problem, where a variety of classifiers can be incorporated to estimate the degradation status of the unit based on the underlying signal paths, i.e., the collected sensor signals after removing the noises. As a result, the proposed method gains great flexibility. It is also capable for sensor selection, able to handle asynchronous sensor signals, and easy to implement in practice. Simulation studies and a case study on the degradation of aircraft engines are conducted to evaluate the performance of the proposed framework in parameter estimation and prognosis.

Data Decomposition for Analytics of Engineering Systems

 

报告人 Xiaowei Yue

Department of Industrial and Systems Engineering

Virginia Polytechnic Institute and State University

 

报告内容摘要：

Data decomposition is an important step for high-dimensional data analytics of complex engineering systems, but it is less emphasized in our current data analytics domain. This paper summarizes the key techniques for data decomposition, and separates them into two categories. One is deterministic decomposition, and the other is stochastic decomposition. The deterministic decomposition captures geometric or algebraic shape from the high-dimensional datasets directly, which is efficient for feature extraction and dimensionality reduction; while the stochastic decomposition provides probabilistic descriptions, and corresponding statistical distributions are estimated from the datasets. A novel methodology framework of data decomposition is proposed to formulate the existing approaches. Based on this methodology framework, some future research opportunities for new methodology development are discussed for data analytics of engineering systems.
