This book was released on 2005-07-25 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: A practical guide to identifying hazards using common hazard analysis techniques Many different hazard analysis techniques have been developed over the past forty years. However, there is only a handful of techniques that safety analysts actually apply in their daily work. Written by a former president of the System Safety Society and winner of the Boeing Achievement and Apollo Awards for his safety analysis work, Hazard Analysis Techniques for System Safety explains, in detail, how to perform the most commonly used hazard analysis techniques employed by the system safety engineering discipline. Focusing on the twenty-two most commonly used hazard analysis methodologies in the system safety discipline, author Clifton Ericson outlines the three components that comprise a hazard and describes how to use these components to recognize a hazard during analysis. He then examines each technique in sufficient detail and with numerous illustrations and examples, to enable the reader to easily understand and perform the analysis. Techniques covered include: * Preliminary Hazard List (PHL) Analysis * Preliminary Hazard Analysis (PHA) * Subsystem Hazard Analysis (SSHA) * System Hazard Analysis (SHA) * Operating and Support Hazard Analysis (O&SHA) * Health Hazard Assessment (HHA) * Safety Requirements/Criteria Analysis (SRCA) * Fault Tree Analysis (FTA) * Event Tree Analysis (ETA) * Failure Mode and Effects Analysis (FMEA) * Fault Hazard Analysis * Functional Hazard Analysis * Sneak Circuit Analysis (SCA) * Petri Net Analysis (PNA) * Markov Analysis (MA) * Barrier Analysis (BA) * Bent Pin Analysis (BPA) * HAZOP Analysis * Cause Consequence Analysis (CCA) * Common Cause Failure Analysis (CCFA) * MORT Analysis * Software Safety Assessment (SWSA) Written to be accessible to readers with a minimal amount of technical background, Hazard Analysis Techniques for System Safety gathers, for the first time in one source, the techniques that safety analysts actually apply in daily practice. Both new and seasoned analysts will find this book an invaluable resource for designing and constructing safe systems-- in short, for saving lives.

Book excerpt: 0 e This is the proceedings of the first annual symposium of the Safety-critical Systems Club (The Watershed Media Centre, Bristol, 9-11 February 1993), which provided a forum for exploring and discussing ways of achieving safety in computer systems to be used in safety-critical industrial applications. The book is divided into three parts, which correspond with the themes of the three days of the symposium. The first - Experience from Around Europe - brings together information on developments in safety-critical systems outside the UK. The second - Current Research - consists of papers on large projects within the UK, which involve collaboration between academia and industry, providing techniques and methods to enhance safety. The final part - Achieving and Evaluating Safety - explores how methods already in use in other domains may be applied to safety, and examines the relationships between safety and other attributes such as quality and security. The papers identify the current problems and issues of interest in the field of safety-critical software-based systems, and provide valuable up-to-date material for those in both academia and industry. The academic will benefit from information about current research complimentary to his own, and the industrialist will learn of the technologies which will soon be available and where to find them.

This book was released on 2023-04-20 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software-Intensive Critical System (SICS) is a relatively rapid emergent technology, which is being deployed in applications where a single software error may lead to extremely severe consequences. Software is touching every aspect of human lives in areas such as aviation, aerospace, automotive, transportation, biomedical and nuclear power plants to name a few. The system safety of SICS is highly dependent on the reliability of software under the assumption that hardware is fault-free. No softwarebased system can be considered completely reliable even if it has been comprehensively tested and even if its accuracy has been confirmed using software testing tools. Software modules of SICS, if executed with undetected and volatile errors may lead to catastrophic accidents. The reason for the occurrence of accidents in SICS may be due to the unsafe states that are undetected during the design phase of the system. Safety of SICS de pends entirely on the safe operations of the software and hence software safety is essential. Software safety, which is a component of overall system safety, refers to the features and measures which guarantee that a SICS operates predictably under normal and abnormal conditions, so as to diminish the probability of occurrence of accidents. Therefore, software in critical systems must be designed and implemented in such a way as to detect and transform an unsafe system state to safe state or a fail-safe state upon occurrence of an unpredictable fault or error during the operation of the critical system. A structured approach to the identification of hazards ensures that, to the extent possible, all potential hazards are identified and assessed. When compared to graphical hazard analysis techniques such as Fault Tree Analysis (FTA), Event Tree Analysis (ETA), Unified Modelling Language (UML) diagrams, Reliability Block Diagrams (RBD), Petri Nets (PN) are well-suited for the analysis of safety-critical data and behaviour in SICS. In this thesis, a new hazard analysis framework for SICS is proposed using the principles of Generalized Stochastic Petri Nets (GSPN). A novel concept called Safety Petri Nets (SPN) is introduced to perform qualitative and quantitative analysis of safety factors and to identify, track and eliminate software-specific hazards thereby assuring an echelon of safety. While traditional methods like FTA are restricted to systems whose components have no stochastic interdependencies the proposed SPN supports stochastic interdependencies and data flow activity. The behaviour of SICS can be represented graphically using SPN based on the dynamic functioning of software considering prime factors like priority transition, immediate transition, and probability for analyzing relation between the places or nodes to identify the hazards that may occur. The graphical representation of SICS corresponds to SPN trees which assist in the detection of errors that may occur during software development of SIC

Download or read book SafeScrum Agile Development of Safety Critical Software written by Geir Kjetil Hanssen and published by Springer. This book was released on 2018-11-23 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the development of safety-critical software and to this end proposes the SafeScrum® methodology. SafeScrum® was inspired by the agile method Scrum, which is extensively used in many areas of the software industry. Scrum is, however, not intended or designed for use with safety-critical systems; hence the authors propose guidelines and additions to make it both practically useful and compliant with the additional requirements found in safety standards. The book provides an overview of agile software development and how it can be linked to safety and relevant safety standards. SafeScrum® is described in detail as a useful approach for reaping the benefits of agile methods, and is intended as a set of ideas and a basis for adaptation in industry projects. The book covers roles, processes and practices, and documentation. It also includes tips on how standard software process tools can be employed. Lastly, some insights into relevant research in this new and emerging field are provided, and selected real-world examples are presented. The ideas and descriptions in this book are based on collaboration with the industry, in the form of discussions with assessment organizations, general discussions within the research fields of safety and software, and last but not least, the authors’ own experiences and ideas. It was mainly written for practitioners in industry who know a great deal about how to produce safety-critical software but less about agile development in general and Scrum in particular.

Download or read book Two Techniques for Software Safety Analysis written by Dingding Lu and published by . This book was released on 2003 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently many safety-critical systems are being built. Safety-critical systems are those software systems where a single failure or hazard may cause catastrophic consequences. Therefore, safety is a property which must be satisfied for safety-critical systems. This research develops techniques to address two areas of software safety analysis in which structured methodologies have been lacking. The first contribution of the paper is to define a top-down, tree-based analysis technique, the Fault Contribution Tree Analysis (FCTA), that operates on the results of a product-family domain analysis. This paper then describes a method by which the FCTA of a product family can serve as a reusable asset in the building of new members of the family. Specifically, we describe both the construction of the fault contribution tree for a product family (domain engineering) and the reuse of the appropriately pruned fault contribution tree for the analysis of a new member of the product family (application engineering). The second contribution of the paper is to develop an analysis process which combines the different perspectives of system decomposition with hazard analysis methods to identify the safety-related scenarios. The derived safety-related scenarios are the detailed instantiations of system safety requirements that serve as input to future software architectural evaluation. The paper illustrates the two techniques with examples from applications to two product families in Chapter One and to a safety-critical system in Chapter Two.
