This thesis presents a quantitative approach to human reliability analysis (HRA) in offshore emergency conditions. Most of the traditional HRA methods use expert judgment techniques as human performance data for emergency situations are not readily available. Expert judgment suffers from uncertainty, incompleteness and when collected from multiple experts, may have conflicting views. This thesis investigates these limitations and presents a proper aggregation method to combine multiple expert judgments using Fuzzy Theory to handle the uncertainty and Evidence Theory to handle the incompleteness and conflict. Furthermore, the traditional approaches of HRA suffer from the unrealistic assumption of independence among different performance shaping factors (PSFs) and associated actions. This thesis addresses this issue using the Bayesian network (BN) approach which can represent the interdependencies among different PSFs and associated actions in a direct and structured way. The integration of Fuzzy Theory and Evidence Theory to the BN approach gives an HRA model that can better estimate the success or failure likelihood of personnel in offshore emergency conditions. Incorporation of environmental factors makes the model applicable for offshore emergencies occurring in harsh environments. Finally the thesis presents a new methodology to collect human performance data using a virtual environment. Using the collected data, a simplified BN model of offshore emergency evacuations is tested and verified.

Human reliability assessments (HRA) are typically completed by eliciting expert opinion. Data used are subjective and are prone to uncertainty and errors. This thesis outlines an HRA method using a Bayesian network (BN) model to evaluate human performance in emergency scenarios using a virtual environment (VE). VE can be used to simulate emergency situations to evaluate human performance in an environment that is controlled and safe and gives access to data that is based on an experimental method, rather than expert opinion. This method involves selecting appropriate performance shaping factors (PSFs) that are varied into different states to create credible scenarios in the VE to observe human performance. The virtual experimental technique provides a way to collect data to quantify a BN. The BN approach is suited to the assessment of human reliability due to its ability to 1) characterize dependency among different performance shaping factors (PSFs) and human errors, 2) incorporate new evidence as it becomes available, and 3) quantify the impact of different PSFs on different individuals. This paper presents an extension of the work done by Musharraf et al. (2014) by introducing PSFs that were purposively selected based on the ability to implement them in the VE, their relevance to real-life situations, and whether they could be controlled to minimize the effects of variables other than the chosen PSF. The PSFs used in this paper are complexity, stress, and uncertainty.

This book presents a bibliographical review of the use of Bayesian networks in reliability over the last decade. Bayesian network (BN) is considered to be one of the most powerful models in probabilistic knowledge representation and inference, and it is increasingly used in the field of reliability. After focusing on the engineering systems, the book subsequently discusses twelve important issues in the BN-based reliability methodologies, such as BN structure modeling, BN parameter modeling, BN inference, validation, and verification. As such, it is a valuable resource for researchers and practitioners in the field of reliability engineering.

Bayesian Reliability presents modern methods and techniques for analyzing reliability data from a Bayesian perspective. The adoption and application of Bayesian methods in virtually all branches of science and engineering have significantly increased over the past few decades. This increase is largely due to advances in simulation-based computational tools for implementing Bayesian methods. The authors extensively use such tools throughout this book, focusing on assessing the reliability of components and systems with particular attention to hierarchical models and models incorporating explanatory variables. Such models include failure time regression models, accelerated testing models, and degradation models. The authors pay special attention to Bayesian goodness-of-fit testing, model validation, reliability test design, and assurance test planning. Throughout the book, the authors use Markov chain Monte Carlo (MCMC) algorithms for implementing Bayesian analyses -- algorithms that make the Bayesian approach to reliability computationally feasible and conceptually straightforward. This book is primarily a reference collection of modern Bayesian methods in reliability for use by reliability practitioners. There are more than 70 illustrative examples, most of which utilize real-world data. This book can also be used as a textbook for a course in reliability and contains more than 160 exercises. Noteworthy highlights of the book include Bayesian approaches for the following: Goodness-of-fit and model selection methods Hierarchical models for reliability estimation Fault tree analysis methodology that supports data acquisition at all levels in the tree Bayesian networks in reliability analysis Analysis of failure count and failure time data collected from repairable systems, and the assessment of various related performance criteria Analysis of nondestructive and destructive degradation data Optimal design of reliability experiments Hierarchical reliability assurance testing
