Title: Efficient Systems Analysis Addressing Complexity and Uncertainties

ABSTRACT: Engineered systems are critical for the functionality of our economic and societal life, they are the technical backbone of our society. A key requirement is, thus, to ensure their reliable performance. Reliability and performance analysis, however, become increasingly complicated due to uncertainties and complexity. In our developed societies, engineered systems are characterized by a rapid growth in scale and complexity. The amount of information needed to model these systems with their complexity is, thus, growing as well. In contrast to this increasing need for information the available information remains almost at the same level. Hence, with increasing scale and complexity the gap between required and available information is growing quickly, so that uncertainties and risks are involved in our models and analyses to a greater extent than ever before. This keynote lecture will highlight selected approaches to address this challenge. Concepts for dealing with epistemic and hybrid uncertainties are discussed, including applications to systems reliability assessment. In order for numerical efficiency to deal with complex systems, survival signature is presented as powerful systems model in combination with advanced simulation technologies for performance and reliability assessment. Novel pathways to capture interdependencies between systems are discussed. Engineering examples are presented to demonstrate the capabilities of the approaches and concepts.

Title: Model- and Non-model-based Damage Detection Methods Using Vibration Data

Abstract: Recent advances in model- and non-model-based damage detection methods using vibration data such as natural frequencies and mode shapes are presented. Two major challenges associated with model-based methods are addressed: accurate modeling of structures and development of a robust inverse algorithm to detect damage, which are defined as the forward and inverse problems associated with model-based damage detection methods, respectively. To resolve the forward problem, new physics-based finite element modeling techniques for fillets in thin-walled beams and bolted joints are developed, so that complex structures with thin-walled beams and/or bolted joints can be accurately modeled with a reasonable model size. To resolve the inverse problem, a robust iterative algorithm that uses Levenberg-Marquardt method is developed to accurately detect locations and extent of damage using a minimum number of measured natural frequencies.
Non-model-based methods that use vibration shapes measured from scanning laser vibrometry, without use of any a priori information of undamaged structures that is usually not available in practice, are introduced. Curvature vibration shapes are compared with those from polynomial fits with proper orders to yield curvature damage indices to identify damage. A new multi-scale differential geometry scheme is developed to calculate curvature vibration shapes. Spatially detailed vibration shapes can be measured by a continuously scanning laser Doppler vibrometer system developed in-house in a rapid and accurate manner. Application of the methodology to detect delaminations in composite plates are demonstrated. Use of operational modal analysis and digital image correlation to detect damage in membranes is also demonstrated.

Title: Management of production systems reliability based on time series modelling

Abstract: The implementation of automation for data analysis and interpretation has become inevitable. Also the realities of IIoT-based companies and easier access to advanced diagnostic solutions are extremely important in this context. The ongoing revolution has established the need for proper and effective analysis of big datasets collected by the systems for the monitoring of machine and machinery component condition.Data from monitoring or maintenance systems are a significant part of any typical database, and they require suitable processing and inferring with respect to taking decisions concerning optimal management of technical infrastructure and its reliability. Examining values collected in the databases, we usually try to design mathematical models which could describe as accurately as possible the investigated phenomenon or a technological process. The behaviour of a system is usually modelled by a stochastic process with discrete time, which is known as a time series. The dynamic prioritization of detected and predicted malfunctions together with risk analysis, planning of the scope of the service, scheduling of the workflow with associated economical optimization should be effectively and automatically analyzed and distributed to defined end users. This requires adequate data analysis techniques and mathematical models for failure prediction. In addition, integration of data from multiple sources is needed to be included in the final decision. From this point of view, some important aspect of production systems reliability management based on time series modelling will be discussed and presented.

TitleDevelopment of a high-resolution X-ray CT microscope for inspection of micro-scale defects in materials

Abstract: The procedure for developing an X-ray CT microscope system for inspection of micro-scale defects in materials is introduced. For generating X-rays of various wave lengths, a simple-structured anode exchangeable X-ray tube was developed. For taking high resolution X-ray projection images, multilayer X-ray mirrors, which can reflect only the characteristic X-ray and increase its intensity were designed and fabricated. Also, a glass thin film scintillator, on which nano-scale column CSI(Tl) layer was formed by DOD (Dynamic Oblique angle Deposition) technique was developed. After line up of the developed components, magnified X-ray projection images of micro-scale defects can be obtained using CCD camera and optical lenses with magnifying power of 40 installed in front of the camera. An improved mathematical CT (Computed Tomography) reconstruction technique, MSIRT (Modified Simultaneous Iterative Reconstruction Technique) and an image interpolation technique for calculating X-ray projection images were developed and combined with each other, and will be applied to obtain magnified CT images of micro-scale defects. Taking the CT images of various micro-scale defects in materials is now under studying.

Title: Competing Failure Analysis in the Internet of Things System with Functional Dependence

Abstract: As an emerging paradigm, the Internet of Things (IoT) aims to improve the quality of life by connecting various smart objects and technologies. These objects often interact with each other, complicating the system reliability modeling and analysis. This talk focuses on one such interaction caused by functional dependence, where the malfunction of certain system component may cause some other components within the same system to become isolated (unusable or inaccessible). In addition, the system components may undergo propagated failures, causing extensive damages to the rest of the system. A time-domain competition exists between the isolation effect and the failure propagation effect; different occurrence sequences can lead to dramatically different system statuses. An efficient combinatorial methodology is discussed, which practices the divide-and-conquer principle to address the competing effects in the reliability analysis of the IoT systems. Examples of the IoT systems in smart homes and body sensor networks are presented to demonstrate the interacting behavior considered and the methodology.

Title: Warranty and Maintenance Strategy of Second-Hand Products Deteriorating with Age

ABSTRACT: The market share of second-hand products (SHP) has increased rapidly because highly developed technologies have resulted in a longer product life and higher prices for new products. For instance, approximately 17.1 million new cars were sold in 2017 in the United States, while sales of used cars reached approximately 42.7 million from both dealers and end users. Therefore it is quiet natural that there is growing interest among researchers and practitioners regarding various warranty and maintenance strategies for SHP. The problems of warranty and maintenance of SHP have been studied in the dealers’ point of view as well as in the users’ point of view. Dealers in SHP typically upgrade the product prior to sale to minimize the warranty costs as well as to enhance the product value although it increases the sale price of the second-hand product due to the upgrade cost. Also dealers should design different types of warranty service for SHP as well as new products, not only to promote product sales, but also to satisfy the users’ needs. Hence it is interesting to study various relationship among upgrade level, the sale price and warranty strategy of SHP. After the warranty period is expired, users of SHP should decide self-maintenance strategy including the length of self-maintenance period and maintenance type. This presentation will review research results regarding upgrade level, sale price and warranty period of SHP, examine maintenance strategy following warranty period of SHP and present recent research results.
