Book excerpt: This paper describes the approach taken by the U.S. Nuclear Regulatory Commission to the treatment of common-cause failure in probabilistic risk assessment of operational events. The approach is based upon the Basic Parameter Model for common-cause failure, and examples are illustrated using the alpha-factor parameterization, the approach adopted by the NRC in their Standardized Plant Analysis Risk (SPAR) models. The cases of a failed component (with and without shared common-cause failure potential) and a component being unavailable due to preventive maintenance or testing are addressed. The treatment of two related failure modes (e.g., failure to start and failure to run) is a new feature of this paper. These methods are being applied by the NRC in assessing the risk significance of operational events for the Significance Determination Process (SDP) and the Accident Sequence Precursor (ASP) program.

Download or read book Multi state System Reliability Assessment Optimization And Applications written by Gregory Levitin and published by World Scientific Publishing Company. This book was released on 2003-03-12 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most books on reliability theory are devoted to traditional binary reliability models allowing for only two possible states for a system and its components: perfect functionality and complete failure. However, many real-world systems are composed of multi-state components, which have different performance levels and several failure modes with various effects on the entire system performance (degradation). Such systems are called Multi-State Systems (MSS). The examples of MSS are power systems where the component performance is characterized by the generating capacity, computer systems where the component performance is characterized by the data processing speed, communication systems, etc.This book is the first to be devoted to Multi-State System (MSS) reliability analysis and optimization. It provides a historical overview of the field, presents basic concepts of MSS, defines MSS reliability measures, and systematically describes the tools for MSS reliability assessment and optimization. Basic methods for MSS reliability assessment, such as a Boolean methods extension, basic random process methods (both Markov and semi-Markov) and universal generating function models, are systematically studied. A universal genetic algorithm optimization technique and all details of its application are described. All the methods are illustrated by numerical examples. The book also contains many examples of application of reliability assessment and optimization methods to real engineering problems.The aim of this book is to give a comprehensive, up-to-date presentation of MSS reliability theory based on modern advances in this field and provide a theoretical summary and examples of engineering applications to a variety of technical problems. From this point of view the book bridges the gap between theoretical advances and practical reliability engineering.

Download or read book Common Cause Failure Treatment in Event Assessment written by and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Event assessment is an application of probabilistic risk assessment in which observed equipment failures and outages are mapped into the risk model to obtain a numerical estimate of the event's risk significance. In this paper, we focus on retrospective assessments to estimate the risk significance of degraded conditions such as equipment failure accompanied by a deficiency in a process such as maintenance practices. In modeling such events, the basic events in the risk model that are associated with observed failures and other off-normal situations are typically configured to be failed, while those associated with observed successes and unchallenged components are assumed capable of failing, typically with their baseline probabilities. This is referred to as the failure memory approach to event assessment. The conditioning of common-cause failure probabilities for the common cause component group associated with the observed component failure is particularly important, as it is insufficient to simply leave these probabilities at their baseline values, and doing so may result in a significant underestimate of risk significance for the event. Past work in this area has focused on the mathematics of the adjustment. In this paper, we review the Basic Parameter Model for common-cause failure, which underlies most current risk modelling, discuss the limitations of this model with respect to event assessment, and introduce a proposed new framework for common-cause failure, which uses a Bayesian network to model underlying causes of failure, and which has the potential to overcome the limitations of the Basic Parameter Model with respect to event assessment.
Download or read book Aircraft System Safety written by Duane Kritzinger and published by Woodhead Publishing. This book was released on 2016-09-12 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft System Safety: Assessments for Initial Airworthiness Certification presents a practical guide for the novice safety practitioner in the more specific area of assessing aircraft system failures to show compliance to regulations such as FAR25.1302 and 1309. A case study and safety strategy beginning in chapter two shows the reader how to bring safety assessment together in a logical and efficient manner. Written to supplement (not replace) the content of the advisory material to these regulations (e.g. AMC25.1309) as well as the main supporting reference standards (e.g. SAE ARP 4761, RTCA/DO-178, RTCA/DO-154), this book strives to amalgamate all these different documents into a consolidated strategy with simple process maps to aid in their understanding and optimise their efficient use. Covers the effect of design, manufacturing, and maintenance errors and the effects of common component errors Evaluates the malfunctioning of multiple aircraft components and the interaction which various aircraft systems have on the ability of the aircraft to continue safe flight and landing Presents and defines a case study (an aircraft modification program) and a safety strategy in the second chapter, after which each of the following chapters will explore the theory of the technique required and then apply the theory to the case study

Download or read book Rethinking Bhopal written by Kenneth Bloch and published by Elsevier. This book was released on 2016-05-27 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rethinking Bhopal: A Definitive Guide to Investigating, Preventing, and Learning from Industrial Disasters is the go-to source for anyone seeking to learn how to improve process safety management (PSM) through applying fundamental asset reliability and incident investigation concepts. The seeds that unified PSM on a global scale were planted in Bhopal, India on December 3, 1984. Since then, considerable progress has been made to protect both workers and communities from catastrophic industrial failures. Industry acknowledges its responsibility to create value with accrued operating experience and that using information received from previous failures is a direct way to prevent future incidents. With this principle in mind, Bloch evaluates modern references related to the Bhopal Disaster, using recognized industrial asset reliability and incident investigation concepts. The practice of objective incident investigation offers a compelling insight into specific decisions and actions that resulted in history’s worst industrial disaster. Recording a fully transparent sequence of events promotes a personal sense of accountability for anyone involved in the manufacturing industry. Lessons learned can be immediately implemented by those with direct PSM, management, engineering, and operating responsibilities. Case histories demonstrate how patterns observed in the timeline leading up to the Bhopal Disaster can be detected in modern incidents and by recognizing these patterns in present-day processes avoids counterproductive operating decisions and unprecedented destruction. This text is instrumental in helping existing organizations re-evaluate their own exposures and risks, and would be a valuable read for any member of a process safety management team. Rethinking Bhopal: A Definitive Guide to Investigating, Preventing, and Learning from Industrial Disasters provides an expansion of knowledge and understanding for the novice in PSM while also providing depth and application considerations to challenge more experienced industry professionals. Note: All royalties from this book go to the Process Safety Heritage Trust Scholarship at Lamar University in Beaumont, Texas, USA. Learn how to improve Process Safety Management (PSM) performance by applying fundamental asset reliability and incident investigation concepts Understand your personal role in detecting and preventing Loss of Primary Containment (LOPC) incidents before they occur Take immediate action to stabilize processes under your control while promoting a systematic approach to eliminating persistent failure mechanisms Includes case histories to helpfully illustrate how to detect potentially destructive patterns in your own organization
