This book presents a series of high performance product design (PD) and development best practices that can create or improve product development organization. In contrast to other books that focus only on Toyota or other individual companies applying lean IPD, this book explains the lean philosophy more broadly and includes discussions of systems engineering, design for X (DFX), agile development, integrated product development, and project management. The "Lean Journey" proposed here takes a value-centric approach, where the lean principles are applied to PD to allow the tools and methods selected to emerge from observation of the individual characteristics of each enterprise. This means that understanding lean product development (LPD) is not about knowing which tools are available but knowing how to apply the philosophy. The book comes with an accompanying manual with problems and solutions available on Springer Extras.

This book investigates Reliability-based Multidisciplinary Design Optimization (RBMDO) theory and its application in the design of deep manned submersibles (DMSs). Multidisciplinary Design Optimization (MDO) is an effective design method for large engineering systems like aircraft, warships, and satellites, which require designers and engineers from various disciplines to cooperate with each other. MDO can be used to handle the conflicts that arise between these disciplines, and focuses on the optimal design of the system as a whole. However, it can also push designs to the brink of failure. In order to keep the system balanced, Reliability-based Design (RBD) must be incorporated into MDO. Consequently, new algorithms and methods have to be developed for RBMDO theory. This book provides an essential overview of MDO, RBD, and RBMDO and subsequently introduces key algorithms and methods by means of case analyses. In closing, it introduces readers to the design of DMSs and applies RBMDO methods to the design of the manned hull and the general concept design. The book is intended for all students and researchers who are interested in system design theory, and for engineers working on large, complex engineering systems.

Grain boundaries are important structural components of polycrystalline materials used in the vast majority of technical applications. Because grain boundaries form a continuous network throughout such materials, their properties may limit their practical use. One of the serious phenomena which evoke these limitations is the grain boundary segregation of impurities. It results in the loss of grain boundary cohesion and consequently, in brittle fracture of the materials. The current book deals with fundamentals of grain boundary segregation in metallic materials and its relationship to the grain boundary structure, classification and other materials properties.

This book presents recent material science-based and mechanical analysis-based advances in joining processes. It includes all related processes, e.g. friction stir welding, joining by plastic deformation, laser welding, clinch joining, and adhesive bonding, as well as hybrid joints. It gathers selected full-length papers from the 1st Conference on Advanced Joining Processes.

This book highlights the concept and applications of Remanufactured Fashion. The first book on this subject, it covers reverse logistics, exemplars, and case studies of remanufactured fashion design. Textile waste is a major issue for all countries, and converting that waste into useful products offers a sensible solution. Remanufactured Fashion is one such sustainable waste management strategy. It involves the conversion of discarded garments into useful retail products, without which they would be dumped at landfills, posing a number of environmental issues. Remanufacturing recovers a product's inherent value once that product no longer fulfills the user's desired needs. The application and use of discarded clothing in remanufacturing processes could greatly reduce the percentage of clothing waste (and mitigate related waste management issues), while also contributing to resource conservation. There has been scant research investigating what is actually involved in the fashion remanufacturing process and how the process could be up-scaled to the mass market in order to achieve greater environmental gains. This book addresses that gap in the literature and examines all aspects pertaining to the concept and applications of Remanufactured Fashion.

This book describes a new control design technique called Coefficient Diagram Method (CDM), whereby practical control engineers without deep control theories and mathematics background can design a good controller for their specific plants. In addition, control experts can solve some complicated design problems. Since the CDM was first introduced in 1998, it reveals from the literature that CDM has provided successful controller designs for a variety of practical control problems. In the last two decades, a great deal of research has been done on CDM, while a growing number of researchers want to learn and utilize the method. However, there has been no textbook to learn it systematically so far. This book is motivated by such a need. It is also suitable as a textbook or reference book for master programs in control engineering.

Originally published in the USSR, Handbook of Reliability Engineering set the standard for the reliability testing of technical systems for nearly three generations of applied scientists and engineers. Authored by a group of prominent Soviet specialists in reliability, it provided professionals and students with the first comprehensive reference covering mathematical formulas and techniques for incorporating reliability into engineering designs and testing procedures for nearly three decades. Now, the Handbook's Russian editor, an internationally recognized reliability expert in his own right, has joined forces with a prominent American engineering professional to bring this indispensable resource to English-speaking audiences. Divided into three major parts, the Handbook details reliability fundamentals, examines common reliability problems and solutions, provides a collection of computation formulas and illustrates practical applications of the methods discussed in twenty-four self-contained chapters. Part One, Probabilistic Reliability, discusses equipment, renewable systems, repairable dual systems, asymptotic methods for very reliable repairable systems, systems with network structures, evaluation of system effectiveness, systems with time redundancy, queuing systems with unreliable service channels, and mechanical equipment. In Part Two, Statistical Reliability, the authors discuss estimation of equipment reliability from tests, acceptance-rejection tests, system confidence limits based on unit tests, acceptance-rejection test plans for complex systems, Bayesian reliability estimation, accelerated tests, reliability growth and Monte Carlo simulations. Part Three, Optimization, offers detailed coverage of optimal redundancy, optimal supply of spare parts, optimal control of inventories of spare parts, optimal maintenance, and optimal technical diagnosis. Each topic is introduced using simple, numerical examples readers can follow step-by-step. Appendices offer a review of probability, stochastic processes and mathematical statistics, standard mathematical formulas used in reliability, useful numerical tables as well as information about where readers can purchase reliability software to apply to their own work in engineering design, life prediction, and more. As reliability theory strengthens its already strong position in modern engineering, the Handbook of Reliability Engineering will continue to provide engineers, statisticians, operations research professionals, and students with one of the most comprehensive treatments of reliability topics in print.
