Many serious accidents have happened in the world where systems have been large-scale and complex, and have caused heavy damage and a social sense of instability. Furthermore, advanced nations have almost ?nished public inf- structureandrushedintoamaintenanceperiod.Maintenancewillbemore- portant than production, manufacture, and construction, that is, more ma- tenance for environmental considerations and for the protection of natural resources. From now on, the importance of maintenance will increase more and more. In the past four decades, valuable contributions to maintenance policies in reliability theory have been made. This book is intended to s- marize the research results studied mainly by the author in the past three decades. The book deals primarily with standard to advanced problems of main- nance policies for system reliability models. System reliability can be mainly improved by repair and preventive maintenance, and replacement, and rel- bility properties can be investigated by using stochastic process techniques. The optimum maintenance policies for systems that minimize or maximize appropriate objective functions under suitable conditions are discussed both analytically and practically. The book is composed of nine chapters. Chapter 1 is devoted to an int- duction to reliability theory, and brie?y reviews stochastic processes needed for reliability and maintenance theory. Chapter 2 summarizes the results of repair maintenance, which is the most basic maintenance in reliability. The repair maintenance of systems such as the one-unit system and multiple-unit redundant systems is treated. Chapters 3 through 5 summarize the results of three typical maintenance policies of age, periodic, and block replacements.

Today there is a high demand for high-precision products. The manufacturing processes are now highly sophisticated and derive from a specialized genre called precision engineering. Precision Manufacturing provides an introduction to precision engineering and manufacturing with an emphasis on the design and performance of precision machines and machine tools, metrology, tooling elements, machine structures, sources of error, precision machining processes and precision process planning. As well as discussing the critical role precision machine design for manufacturing has had in technological developments over the last few hundred years. In addition, the influence of sustainable manufacturing requirements in precision processes is introduced.

Drawing upon years of practical experience and using numerous examples and illustrative applications, David Dornfeld Dae-Eun Lee cover precision manufacturing as it applies to:

The importance of measurement and metrology in the context of Precision manufacturing.

The role of sensors in precision manufacturing and how they can reduce uncertainty in systems introduced by interfaces between machine elements, process elements and materials, etc.

New and emerging fields of micromachining and nano manufacturing and their importance and impact on precision manufacturing.

Adherence to precision manufacturing techniques during the production process prevents waste, increases interchangeability among similar parts, lowers the manufacturing cost and increases quality.

Precision Manufacturing will be of interest to design engineers, quality engineers and manufacturing engineers, academics and those who may or may not have previous experience with precision manufacturing, but want to learn more.

Structural Reliability Analysis and Prediction, Third Edition is a textbook which addresses the important issue of predicting the safety of structures at the design stage and also the safety of existing, perhaps deteriorating structures.

This book presents models and statistical methods for the analysis of recurrent event data. The authors provide broad, detailed coverage of the major approaches to analysis, while emphasizing the modeling assumptions that they are based on. More general intensity-based models are also considered, as well as simpler models that focus on rate or mean functions. Parametric, nonparametric and semiparametric methodologies are all covered, with procedures for estimation, testing and model checking.

The basic logic is very simple. Countries around the globe have a need for more electrical generating capacity because of increases in population and increases in energy use per capita. The needs are constrained by the requirement that the ba- load energy source be economical, secure, and not emit climate-changing gases. Nuclear power fits this description. Therefore, many countries that have not had a nuclear power program (or only had a small program) see a need to develop one in the future. However, the development of a national nuclear energy program is not so simple. The purpose of the NATO Advanced Research Workshop on Nuclear Power and Energy Security was to contribute to our understanding of how these programs might evolve. The workshop took place 26-29 May 2009 in Yerevan, Armenia. Approximately 50 participants discussed the infrastructure that is needed and some of the reactor options that might be considered. The papers in this book helped define the discussion that took place. The infrastructure that is needed includes a legal framework, a functioning regulator, a plan for waste disposal, a plan for emergency response, etc. These needs were explained and just as importantly, it was explained what international, bilateral, and regional cooperation is available. Although there were many co- tries represented, the Armenian experience was of particular interest because of where the meeting was located. The papers on reactor options covered both innovative and evolutionary designs.

It reports on the design of systems and devices to improve the quality, safety, efficiency and effectiveness of patient care, and discusses findings on improving organizational outcomes in the healthcare setting, as well as approaches to analyzing and modeling those work aspects that are unique to healthcare. Based on papers presented at the AHFE 2019 International Conference on Human Factors and Ergonomics in Healthcare and Medical Devices, held on July 24-28, 2019, in Washington, DC, USA, the book highlights the physical, cognitive and organizational aspects of human factors and ergonomic applications, and shares various perspectives, including those of clinicians, patients, health organizations, and insurance providers. Given its scope, the book offers a timely reference guide for researchers involved in the design of medical systems, and healthcare professionals managing healthcare settings, as well as healthcare counselors and international health organizations.

This book covers a wide range of management issues, concerning planning, control and continuous improvement. It especially focuses on the management of the enterprise and production processes in the era of globalization, discussing the process of transferring production to developing countries, covering issues in technological culture, and reporting on quality control issues and on problems related to continuous process improvement. Modern strategies such as Six Sigma and lean manufacturing are also discussed. Another topic concerns the management of the education sphere, and how to develop the latter to prepare employees to the changes brought by the technical development. Based on papers presented at the 6th International Scientific-Technical Conference MANUFACTURING 2019, held in Poznan, Poland on May 19-22, 2019, this book bridges issues in quality engineering with concepts of ergonomics and sociology, thus offering a timely, practice-oriented guide to both the engineers and managers of the future.

The objective of this book is to help at-risk organizations to decipher the "safety cloud", and to position themselves in terms of operational decisions and improvement strategies in safety, considering the path already travelled, their context, objectives and constraints. What link can be established between safety culture and safety models in order to increase safety within companies carrying out dangerous activities? First, while the term "safety culture" is widely shared among the academic and industrial world, it leads to various interpretations and therefore different positioning when it comes to assess, improve or change it. Many safety theories, concepts, and models coexist today, being more or less appealing and/or directly useful to the industry. How, and based on which criteria, to choose from the available options? These are some of the questions addressed in this book, which benefits from the expertise of its worldwide famous authors in several industrial sectors.

This open access work presents selected results from the European research and innovation project IMPROVE which yielded novel data-based solutions to enhance machine reliability and efficiency in the fields of simulation and optimization, condition monitoring, alarm management, and quality prediction.

The conventional approach to risk communication, based on a centralized and controlled model, has led to blatant failures in the management of recent safety related events. In parallel, several cases have proved that actors not thought of as risk governance or safety management contributors may play a positive role regarding safety. Building on these two observations and bridging the gap between risk communication and safety practices leads to a new, more societal perspective on risk communication, that allows for smart risk governance and safety management.

How can a scalable and efficient quality management mechanism for cloud labor services be designed in a way that it delivers results with a well-defined level of quality to the requester? Cloud labor services are a specific form of crowdsourcing: A coordination platform serves as an interface between requesters who need to get work done and a large crowd of workers who want to perform work. An early example of such a platform is Amazon's Web marketplace Mturk, on which service requesters can publish open calls for so-called human intelligence tasks (HITs). Robert Kern's work makes a considerable contribution toward solving the quality problem for scalable human work. On the basis of a comprehensive framework of cloud labor, he develops a set of methods to conceptually measure and aggregate the quality of human work results, implements a platform to put those methods to work, and evaluates their application in a number of very compelling, real-world scenarios successfully combining concepts from statistics, information technology, and management. Reading this book will be beneficial to novices in cloud labor services looking for orientation in this new field as well as to advanced researchers and practitioners developing cloud quality concepts.

This Brief evaluates the consequences of protein modifications in cheeses, with special emphasis on mozzarella cheeses. It explains the influence of biogenic amines on food quality and safety. As certain biogenic amines display a toxic potential to humans, considerable research has been undertaken in recent years to evaluate their presence in fermented foods, such as cheeses. This Brief summarizes how the presence of amines is influenced by different factors such as cheese variety, seasoning and microflora. The authors compare typical profiles of different products, e.g. ripe vs. unripe cheeses, focusing also on the different types of mozzarella cheeses. The Brief also introduces several analytical methods and simulation techniques, which are being used to evaluate the evolutive profiles of different selected molecules, protein aggregation, or proteolysis.

HACCP: A Practical Approach, 3rd edition has been updated to include the current best practice and new developments in HACCP application since the last edition was published in 1998. This book is intended to be a compendium of up-to-date thinking and best practice approaches to the development, implementation, and maintenance of HACCP programs for food safety management.

Introductory chapters set the scene and update the reader on developments on HACCP over the last 15 years. The preliminary stages of HACCP, including preparation and planning and system design, are covered first, followed by a consideration of food safety hazards and their control. Prerequisite program coverage has been significantly expanded in this new edition reflecting its development as a key support system for HACCP. The HACCP plan development and verification and maintenance chapters have also been substantially updated to reflect current practice and a new chapter on application within the food supply chain has been added. Appendices provide a new set of case studies of practical HACCP application plus two new case studies looking at lessons learned through food safety incident investigation. Pathogen profiles have also been updated by experts to provide an up-to-date summary of pathogen growth and survival characteristics that will be useful to HACCP teams.

The book is written both for those who are developing HACCP systems for the first time and for those who need to update, refresh and strengthen their existing systems. New materials and new tools to assist the HACCP team have been provided and the current situation on issues that are still undergoing international debate, such as operational prerequisite programs. All tools such as decision trees and record-keeping formats are provided to be of assistance and are not obligatory to successful HACCP. Readers are guided to choose those that are relevant to their situations and which they find are helpful in their HACCP endeavors."

Hinter dem Begriff "Verteilte Systeme" verbergen sich heutzutage so unterschiedliche Konzepte wie Parallelrechner, Rechnernetze, Telekooperation und Multimediaanwendungen. Hauptanwen- dungsfeld in diesem Buch ist die Telekooperation. Der Begriff" Verteiltes System", so wie er in diesem Buch verwendet wird, lasst sich informell - und in der Sprechweise der Tele- kooperation -charakterisieren durch: - Kooperationspartner (Menschen und/oder Maschinen, allgemein autonome Systeme genannt), - Kooperationsziele, deren Erreichen gemeinsames Handeln der beteiligten Kooperationspartner erfordert (beispielsweise Abschluss eines Vertrags, Erarbeitung einer Spezifikation fur ein technisches System, Fernwartung eines Systems, ... ) und - Komm unika tionsmedien, die Kooperationspartner miteinander verbinden (z. B. zum Transport von Sprach-, Bild-, oder Text- information). Der Transport von Information aus Sicht eines Kommunikations- mediums ist gekennzeichnet durch die Funktionen Senden, UEber- tragen, Vermitteln und Empfangen. Aus Sicht der Kooperations- partner sind die Produktion der zu sendenden und die Konsumtion der empfangenen Information wichtige Begriffe. Kommunikationsmedien erbringen Kommunikationsdienst- leistungen, die von den Kooperationspartnern in Anspruch genommen werden koennen. Zu den Eigenschaften verteilter Systeme gehoeren - Unsicherheit eines autonomen Systems uber den Zustand der anderen an der Kooperation beteiligten autonomen Systeme, - Nebenlaufigkeit und Nichtdeterminismus der Aktionen der autonomen Systeme als Ausflug ihrer Unabhangigkeit, 2 1 Einleitun[!, - Synchronisation ihrer Aktionen als Anforderung aus dem festgelegten Kooperationsziel, - aufeinander abgestimmte Betriebsmittelverwaltung (z. B. Puffer- verwaltung von Sender und Empfanger), - aufeinander abgestimmte Mechanismen zur Fehlererkennung und Fehlerbehebung, u. s. w.

Zwar fallt die Zahl aller Arbeitsunfalle in der Bundesrepublik Deutschland kontinuierlich. Die Zahl der Arbeitsunfalle bei der Instandhaltung steigt jedoch. Bereits heute ereignen sich ein Viertel aller toedlichen Arbeitsunfalle bei Instandhaltungsarbeiten. Der Anteil der Instandhaltungsunfalle wird sich in den nachsten Jahren - u.a. durch die Einfuhrung neuer Technologien - weiter erhoehen. Die bisher eingesetzten Methoden zur Ermittlung der Gefahrdungen erweisen sich als nicht so geeignet. Aus diesem Grund wird eine neue Methode zur Ermittlung von Gefahrdungen aufgestellt. Ein Praxistest demonstriert die Praktikabilitat. Eine leichte Einsetzbarkeit der entwickelten Methode wird dadurch gewahrleistet, dass die einzelnen Arbeitsschritte fur den Praktiker ausreichend beschrieben werden. Mit der vorliegenden Arbeit wird eine allgemeingultige Methode zur Ermittlung von Gefahrdungsschwerpunkten bei Instandhaltungsarbeiten aufgebaut, die zur Erhoehung der Arbeitssicherheit in allen Unternehmen eingesetzt werden kann. Die Methode bietet den Vorteil, dass sie auch in anderen Bereichen der Produktion - wie z.B. in der Fertigung und im Transportwesen - eingesetzt werden kann.
