To achieve commercialization and wide acceptance in industrial application, reliability analysis for complex evolving systems with multiple failure processes becomes increasingly important. The common assumption in analyzing reliability of such systems is that these multiple failure processes are independent, which may lead to the miscalculation of system reliability. To assist engineers with design, manufacturing and maintenance of complex systems, new reliability models that account for the dependence among multiple failure processes need to be developed to accurately predict the lifetime of these systems. This research aims to develop probabilistic reliability models and analytical tools for systems with dependent competing failure processes, and explore cost-effective maintenance policies based on our reliability analysis. Different dependent patterns among competing failure processes are explored for single-component systems. When the arrival of external shocks diminishes the strength of material, we propose reliability and maintenance models for systems with a shifting, dependent hard failure threshold. When shocks impact the degradation process in different manners, we model zoned shock effects on stochastic degradation, and develop reliability functions for such dependent stochastic failure processes. Case studies of micro-electro-mechanical systems and stent devices are used to demonstrate our models, where Monte Carlo importance sampling is used to estimate system reliability. We extend our models on single-component systems to a broader range of multi-component systems experiencing multiple failure processes, which presents more challenges on modeling the interaction and dependence among different components. A new reliability model and a unique condition-based maintenance model are proposed for complex systems with dependent components subject to respective degradation processes, and the dependence among components is established through environmental factors. Another condition-based maintenance policy is developed for power transformers using Markov decision processes, where a power transformer with multiple components is modeled as a multi-state system. The proposed reliability and maintenance models can be implemented to address the critical quality and reliability problems of evolving devices and many other systems with multiple dependent competing failure processes and multiple dependent components. The developed models and analytical tools can facilitate product design, manufacturing and maintenance, and enhance system reliability and availability.

Condition-based monitoring is an accepted feature of many industries: petro-chemical, power generation, coal mining and steel-making, for instance. In manufacturing, its application has been somewhat muted. This text attempts to present the fundamental justification for condition-based maintenance together with enough analytic and practical guidance for its implementation. There are chapters on the two dominant techniques of vibration and debris analysis. Also, basic diagnostic methods are given along with a presentation of the systems approach to condition monitoring. A detailed case study shows the practical application of the techniques presented. Finally, future developments in the use of expert systems and A1 techniques are highlighted. Condition-based Maintenance and Machine Diagnostics gives details of both off-the-shelf solutions and analytic diagnostic techniques to enable a bespoke solution to be developed. It is suitable for senior undergraduates and postgraduates in the field of manufacturing and industrial engineering, and it furnishes managers in industry with sufficient information to judge the usefulness of the techniques for their particular application.

Maintenance serves a critical role in manufacturing systems by ensuring that machines and other assets remain in a productive working condition. The primary objective of maintenance optimization is to determine when to conduct maintenance and which machines should be maintained. Recent advances in industrial maintenance have sought to use online information obtained from sources such as machine sensors and manufacturing execution system software to provide real-time decision support. Such predictive maintenance strategies combine abundant online manufacturing data with techniques in simulation, planning, and artificial intelligence to make effective maintenance decisions and support the overall performance of the system. In this dissertation we examine several challenges associated with adopting real-time maintenance decision support in complex manufacturing systems. One such challenge is that of modeling complex machine configurations that are often found in modern manufacturing systems. It can be difficult or impossible to model the behavior of these systems analytically without imposing unrealistic simplifying assumptions. One of the goals of this work is therefore to propose a method of maintenance optimization and planning that is generalizable to arbitrarily configured systems. We also introduce a discrete-event simulation package that has been developed as a part of this work and is capable of modeling these systems of interest. Additionally, real-world manufacturing systems are typically subject to constraints on available maintenance resources which limits the number of maintenance jobs that may be conducted simultaneously. In these settings, the maintenance planner must determine how to prioritize competing maintenance activities and allocate these limited resources throughout the system. This work addresses these challenges by proposing a simulation-based maintenance optimization and planning approach to seek an optimal maintenance policy and prioritize maintenance in complex systems. We formulate condition-based maintenance policy optimization as a discrete optimization via simulation problem and seek a solution using the Gaussian Markov Improvement Algorithm and a genetic algorithm. The result is a degradation threshold for each machine in the system that determines when a machine should request maintenance. To overcome the problem of capacity-constrained maintenance resources, we first propose a dynamic priority scheduling heuristic that aims to minimize throughput disruption due to downtime for maintenance. We then improve upon this scheduling heuristic by employing a reinforcement learning approach to seek the best maintenance action in each state of the system. We use Monte Carlo tree search to progressively build a search tree within the system state space and evaluate alternative sequences of actions in order to find that which maximizes the expected reward. We demonstrate that our proposed method of online prioritization results in improved system-level performance when compared to commonly used maintenance prioritization methods. Furthermore, we apply a case-based reasoning framework to retain and reuse relevant experience that improves the decision-making efficiency over time. In addition to improved system productivity, the proposed approach results in reduced time needed to identify optimal maintenance actions which is particularly important when critical maintenance decisions must be made quickly.
