Title: Maintenance and warranty policy for repairable system subject to lemon law conditions

Abstract: The search for an optimal maintenance and warranty policy has been a hot issue for a long time in the field of reliability engineering and a number of research results have been proposed in the literature. This presentation focuses on the maintenance and warranty policy for a repairable system subject to the “lemon law” conditions and its recent related works. The lemon law is a regulation to protect the customers from the defectives when the system failures occur repeatedly or the accumulated repair time exceeds a certain limit and is widely enforced over most industrialized nations. In most situations, the period during which the lemon law is effective is shorter than the warranty period and is set different from region to region. Recent research works on various situations are reviewed and the case for mutual interaction of the system components are briefly discussed as well.

Title: Safety and reliability of autonomous systems – from design, development to operation

Abstract: Autonomous vehicle is probably the most widely discussed applications of AI techniques and broadly speaking, autonomous systems have helped us to improve the quality and productivity, at work and at home. However, as many of intelligent systems are also safety-critical, how to design and develop such system is of great concern. Testing and managing the operation of such system will also be very critical. We cannot wait till systems are fully developed and operational, and managing the design and development of AI systems is what engineering management community should pay attention to. Furthermore, for intelligent systems, the data availability and accuracy should also be considered and managed, especially due to the dynamic nature of the data sources and issues with sensor degradation. In this talk, some of these issues will be discussed, with reference to the development of autonomous vehicles and robotics in different applications.

Tadashi Dohi, PhD, Professor

Title: Reliability Evaluation of Modular Software Systems with Bug Prediction

Abstract: Software bug prediction aims at predicting bug-prone modules in advance during the module testing, and is reduced to a statistical discrimination problem, where several kinds of machine learning algorithms are applied to predict the bug-prone probability in each module before conducting the module test. However, it should be noted that the reliability evaluation of  modular software systems with bug prediction has not been considered yet in the past literature. In my talk, we focus on the fact that estimates of the bug-prone probabilities are mutually independent but not identical, and develop a reliability evaluation method for the modular software systems with bug prediction. Throughout numerical illustrations with actual software development project data, we present how to utilize our reliability modeling and inference in the testing of modular software systems.

Title: Phase-changing gels for thermal and electric energy harvesting

Abstract: Hydrated-salt-induced phase changes can be leveraged toward the development of cost-effective and environmentally friendly materials with many invaluable functions, including interchangeable states, energy (heat, electricity, and mechanical) harvesting, and switchable adhesion. However, the use of existing materials presents challenges such as limited supercooling, uncontrolled nucleation, a narrow operational temperature range, and cyclic instability, which collectively limit the practical applications of phase-changing gels. In this study, we propose a strategy that utilizes the synergistic effect of hydrated sodium acetate trihydrate (SAT) and glycerol to develop phase-changing gels with excellent supercoolability (below –80 ℃). The proposed strategy concurrently resolves all the aforementioned issues by creating a stronger yet switchable solvation barrier around the salt ions in the gel network. As a proof of concept, we rationally integrate SAT and glycerol within a polymer gel matrix at the molecular level to develop a supersaturated glycerogel. This supersaturated glycerogel possesses a cyclic, on-demand, and sustainable (by concentrating sunlight) structural transformability (~2000-fold change in stiffness) and exhibits prolonged environmental and mechanical stability. In addition, we demonstrate its ability to generate high-performance heat (~42 ℃) and thermoelectric voltages (~336 mV) at environmental temperatures of −30–37 ℃. Furthermore, it exhibits stable shape adaptability (~100%) and shape-memory ability (~100%), along with extremely tough and reversible adhesiveness (debonding energy for gel/glass adhesion: ~800 J m-2). The utilization of the SAT/glycerol synergy promotes the development of diverse high-performance phase-changing gels for advanced medical and technological applications.

Title: Analysis of Operational Data to Support Maintenance Planning of Floating Offshore Wind Turbines

Abstract: An overview of the overall wind energy production trends worldwide, including offshore evolution. The general characteristics and mode of operation of the wind turbines are presented, and the use of FMEA to identify the modes of failure and their risk levels is discussed. Reference is made to a recently acquired database of failure data of onshore and bottom-fixed offshore wind farms in China, discussing the features of the data and the assessments they allow. Given the lack of data for floating offshore wind turbines, a method is presented to adjust failure data from onshore to offshore conditions and from fixed offshore to floating offshore wind turbines, using expert opinions, and the problems of estimating failure rates of the various components are addressed. The use of artificial intelligence methods in the analysis of the data is discussed and some approaches are described. The support that data sets also provide to the analysis of maintenance actions is also discussed and some results are presented.
