Dependability has always been an vital attribute of operational systems, regardless of whether they are highly-specialised (like electricity generating plants) or more general-purpose (like domestic appliances). This volume provides a highly-readable overview of the topic, concentrating on dependability as a life-cycle management issue rather than as a technical subject. Specifically avoiding technical language and complex mathematics, it is designed to be accessible to readers at all levels. It will be of particular interest to project managers and software engineers in industries where dependability is of particular importance, such as aerospace, process control, and mining. It will also provide useful reading material for students taking courses with modules in dependability. Felix Redmill and Chris Dale have both worked in industry for over 15 years, and now run successful consultancy businesses.

This ground-breaking title presents an interdisciplinary introduction to the subject of Dependability and how it applies in medicine generally and in neurology in particular. Dependability is the term applied in engineering and industry to a service that is safe, reliable and trustworthy. Dependable systems use a variety of methods to deliver correct service in the face of uncertainty resulting from misleading, erroneous information, and system faults. Dependable systems result from the application of systematic methods in design, operation, and management to deliver their services. Dependability in Medicine and Neurology presents the philosophy and ideas behind the specific methods of dependability and discusses the principles in the context of medical care and neurologic treatment especially. Patient case vignettes are used widely to illustrate key points. A first-of-its-kind title and based on the author’s many years of teaching these principles to medical colleagues throughout the United States, Dependability in Medicine and Neurology will inspire readers to develop applications for their specific areas of clinical practice. Intended for physicians (especially neurologists), medical students, nurses, and health administrators, Dependability in Medicine and Neurology is an indispensable reference and important contribution to the literature.

Reliability, Maintainability, and Supportability play a crucial role in achieving a competitive product. While manufacturing costs are important for the success of a product, they are not the sole domains in realizing its competitive edge. Improved manufacturing and operating quality and performance coupled with reduced acquisition cost and in-service cost of ownership are important in achieving business success. It is the early phase of design which offers the greatest opportunity to address these requirements, and thus create life cycle effectiveness. The main objective of Reliability, Maintenance and Logistic Support - A Life Cycle Approach is to provide an integrated approach to reliability, maintainability, maintenance and logistic support analysis. We not only look at the ways we can improve the design process to ensure the product offers value for money, but we also consider how the owners can get the most from these products once they have entered service. The approach provides a meaningful way of integrating reliability, maintenance and supportability to enhance the product performance and sales opportunities. Hence, the book covers the following objectives: (1) Introduce the concepts of reliability, maintainability and supportability and their role in the system life cycle and effectiveness. (2) Introduce the basic probability and statistical techniques that are essential for modelling reliability, maintainability and supportability problems. (3) Introduce reliability measures: how to predict them; how to determine from in-service real-world data; how to use them. (4) Analysis of advanced models in Reliability. (5) Discuss basic and advanced concepts in both maintainability and maintenance including preventive, corrective and condition based maintenance. (6) Discuss maintenance management and optimization concepts, such as reliability-centered maintenance and age-related maintenance. (7) Provide basic concepts in supportability and Integrated logistic support. (8) Discuss techniques for design for reliability, maintainability and supportability. (9) Analysis of simple and advanced models in spares forecasting and optimization. (10) Discuss data analysis, data management and data mining techniques.

Reliability Engineering – A Life Cycle Approach is based on the author’s knowledge of systems and their problems from multiple industries, from sophisticated, first class installations to less sophisticated plants often operating under severe budget constraints and yet having to deliver first class availability. Taking a practical approach and drawing from the author’s global academic and work experience, the text covers the basics of reliability engineering, from design through to operation and maintenance. Examples and problems are used to embed the theory, and case studies are integrated to convey real engineering experience and to increase the student’s analytical skills. Additional subjects such as failure analysis, the management of the reliability function, systems engineering skills, project management requirements and basic financial management requirements are covered. Linear programming and financial analysis are presented in the context of justifying maintenance budgets and retrofits. The book presents a stand-alone picture of the reliability engineer’s work over all stages of the system life-cycle, and enables readers to: Understand the life-cycle approach to engineering reliability Explore failure analysis techniques and their importance in reliability engineering Learn the skills of linear programming, financial analysis, and budgeting for maintenance Analyze the application of key concepts through realistic Case Studies This text will equip engineering students, engineers and technical managers with the knowledge and skills they need, and the numerous examples and case studies include provide insight to their real-world application. An Instructor’s Manual and Figure Slides are available for instructors.

Dependability Problems of Complex Information Systems

Author: Wojciech Zamojski

Publisher: Springer

ISBN:

Category: Technology & Engineering

Page: 189

View: 467

This monograph presents original research results on selected problems of dependability in contemporary Complex Information Systems (CIS). The ten chapters are concentrated around the following three aspects: methods for modelling of the system and its components, tasks – or in more generic and more adequate interpretation, functionalities – accomplished by the system and conditions for their correct realization in the dynamic operational environment. While the main focus is on theoretical advances and roadmaps for implementations of new technologies, a much needed forum for sharing of the best practices is also presented. CIS systems, being the most complex yet most reliable technical structures engineered by man, present many challenges throughout their lifecycle. Difficulties in modelling, design, implementation and maintenance come not only from involved, widely distributed technical and organizational structures (comprising both hardware and software resources), but even more from complexity of the information processes (data processing, monitoring, resource allocation, dynamic reconfiguration, etc.) which are realized in the operational, often hostile environment. Furthermore, all the issues need to be dealt with taking into account a number of additional factors, such as uncertainties of human interactions, safety criteria and security demands or economic and environmental constrains.

Reliability and Risk of Structural Systems Under Progressive and Sudden Damage

Structural systems are usually subjected to progressive and/or sudden damage throughout their lifetime. Damage can cause a reduced level of safety and increase the life-cycle cost. In order to keep the safety and proper functionality of structures above prescribed thresholds, maintenance interventions should be well planned. Informed decision making for maintaining the required safety and serviceability levels of structural systems under uncertainty during their lifetime can only be achieved through integrated life-cycle management planning. Structural performance assessment and prediction, optimization of inspection and monitoring activities, updating the performance with information from inspection and monitoring, optimization of maintenance and repair activities and decision making are the main tasks of an integrated life-cycle management framework. Accurate prediction and quantification of life-cycle performance is the most critical task in a life-cycle management framework. Uncertainty is inevitable in all aspects of this framework. Aggressive environmental conditions may cause the strength of a structure to deteriorate progressively in time. The deterioration process is complex and contains high uncertainty. Therefore, probabilistic methods are required for accurate assessment of structural performance. Reliability-based performance measures are the primary tool for structural management optimization frameworks. Extreme events such as floods, earthquakes, and blasts may cause sudden damage to structures. A structure must be able to withstand local damage without experiencing disproportionate consequences. Performance measures such as reliability, redundancy, robustness, vulnerability and damage tolerance should be considered in the life-cycle management of structures. Risk-based approaches provide the means of combining the probability of structural failure with the consequences of this event. There is the need to effectively incorporate the risk-based performance measures into the life-cycle management frameworks by accounting for the probabilities of occurrence of failure events and the associated consequences using scenario-based approaches in a computationally efficient manner. The main objective of this study is to develop means for integrating the reliability-based and risk-based performance indicators in a life-cycle management framework for structures undergoing progressive and sudden damage. An approach for quantifying time-variant reliability, redundancy, vulnerability, and robustness of structural systems in a life-cycle context is developed. A methodology for quantifying lifetime risk associated with the component failure and risk-based robustness of bridge superstructures is proposed. Furthermore, a risk-based maintenance optimization methodology for deteriorating bridges to establish optimum maintenance plans is proposed. A methodology to assess the time-dependent expected losses and risk-based robustness of highway bridge networks consisting of deteriorating bridges is established. In addition, a probabilistic approach for performance assessment of ship hulls under sudden damage accounting for different operational conditions is developed. Finally, the applicable range of simple expressions based on first-order second-moment method for bridge system reliability assessment is provided by investigating the amount of error associated with these simple expressions.
