This book describes the design experience of automatic machines and the theoretical background for controlling them. Unlike the existing literature, it includes design concepts and their relationship with the dynamic behavior of automated devices, and links the dynamic response of the machine elements with the actuators that constitute an automatic machine. As such, it demonstrates that it is vital to properly model any automatic machine as a single system and find the final response to have a good design and control scheme. The introduction describes the background for designing automatic machines, their uniqueness in machine design, and the need to understand dynamic behavior. The following chapters provide the background for modeling multibody systems, examples of typical automatic machines, and the basis for determining the dynamic response of the most common actuators (motor, pneumatic, and hydraulic pistons and valves). The fourth chapter describes the dynamic response of the most common sensors utilized in automatic machines, while the fifth chapter includes the dynamic models of the machine elements that connect the actuators with the end effects (specific tools for each particular application). The final chapters contain examples of dynamic models for different automatic machines, including all the elements that affect the final response, and describe the simulation techniques (and their application to the examples) and the application of the transfer function for estimating the transient response of automatic machines.
Balancing of rotors is an indispensable process for the quality management, involving many stages from design to commissioning. With every further development of rotors - with new concepts, materials and machining methods - the demands on balancing technology change. In the search for the optimum solution to these complex tasks, no patent remedies will help, but only a sound knowledge of the theoretical background of balancing, its practical implementation and the performance of the various balancing systems.This book is intended to support systematic familiarisation with the subject and ongoing training - in practice as well as in theory.The focus of current balancing standards is on deviations that occur during balancing - intentionally generated, or accidentally created. They must be properly analysed and taken into account in order to determine the permissible indications for residual unbalance. In addition, the acceptance criteria were specified so that the balancing objective - the targeted balancing quality - can be reliably achieved.When balancing rotors with shaft-elastic behaviour, work is often still carried out according to outdated patterns. For this reason, the new modal approach was further elaborated - partly on the basis of DIN ISO 21940 Part 12, Supplement 1. For practical application, the difficult choice of compensation planes and the relevant bending eigenmodes is explained by means of examples.

This book considers a broad range of areas from decision making methods applied in the contexts of Risk, Reliability and Maintenance (RRM). Intended primarily as an update of the 2015 book Multicriteria and Multiobjective Models for Risk, Reliability and Maintenance Decision Analysis, this edited work provides an integration of applied probability and decision making. Within applied probability, it primarily includes decision analysis and reliability theory, amongst other topics closely related to risk analysis and maintenance. In decision making, it includes multicriteria decision making/aiding (MCDM/A) methods and optimization models. Within MCDM, in addition to decision analysis, some of the topics related to mathematical programming areas are considered, such as multiobjective linear programming, multiobjective nonlinear programming, game theory and negotiations, and multiobjective optimization. Methods related to these topics have been applied to the context of RRM. In MCDA, several other methods are considered, such as outranking methods, rough sets and constructive approaches. The book addresses an innovative treatment of decision making in RRM, improving the integration of fundamental concepts from both areas of RRM and decision making. This is accomplished by presenting current research developments in decision making on RRM. Some pitfalls of decision models on practical applications on RRM are discussed and new approaches for overcoming those drawbacks are presented.

In diesem Open-Access-Buch wird eine Methode zur Adaption, Integration und Anwendung von bestärkenden Lernverfahren (Reinforcement Learning) für die Produktionsablaufplanung beschrieben. Die Methode wird anhand von typischen Problemstellungen der Produktionsablaufplanung hergeleitet und evaluiert. Die Produktionsablaufplanung ist eine Kernaufgabe der Produktion und Logistik, bei welcher Aufträge auf Ressourcen so verteilt und in Reihenfolge gebracht werden müssen, dass geforderte Nebenbedingungen der Planung erfüllt werden. Entsprechende Optimierungsprobleme sind meist NP-schwer, wodurch eine optimale Lösung gewöhnlich nicht unter wirtschaftlichen Bedingungen erzielbar ist. In der Industrie werden stattdessen Prioritätsregeln, Heuristiken oder Metaheuristiken verwendet, die entweder zeiteffizient zu Lasten der Lösungsgüte rechnen oder qualitativ hochwertige Lösungen unter hohem Rechenaufwand erzeugen. Das bestärkende Lernen ist eine Unterart des maschinellen Lernens und eine weitereKlasse potenzieller Lösungsstrategien. Probleme der Produktionsablaufplanung sind insoweit vergleichbar, als dass sie sich ebenfalls als stufenartige Entscheidungsketten modellieren lassen. Trotz ihrer Vorteile existiert bisher kaum allgemeines Wissen hinsichtlich der Anwendung des bestärkenden Lernens für die Produktionsablaufplanung.
Industry 4.0 is changing how we manage operations to drive systems more intelligently. Technologies and applications are rapidly evolving. Disruptive technologies, such as artificial intelligence, big data, cloud computing and digital twin, are shaking up different industries and have motivated us to revisit engineering and management tools for improving system design, efficiency, effectiveness, reliability, and responsiveness. While these emerging technologies have powered new applications, novel industrial engineering methodologies are required to achieve the goals.Industrial Engineering was sprouted from major engineering disciplines that called for better professional understanding of industrialization. Ever since, the discipline of Industrial Engineering has been the star role player in confronting emerging industries; be it manufacturing, service, high tech products, outer space technology, information technology, industrial policy, ergonomics, and now the world's greatest concern, sustainable development.This book presents the state-of-the-art in industrial engineering research from different countries and cities around the globe. The book covers a wide range of topics in industrial engineering, including: Demand Chain Management, E-business / Information Technology, Evolutionary Algorithm, Green Manufacturing/Management, Health Care Systems and more.
This book is the continuation of the textbook Lean Compendium - Introduction to Modern Manufacturing Theory. It extends the theory of mathematical modeling to batch & queue-based cyber-physical production systems. To facilitate learning, the book continues to develop a Cartesian-derived understanding of the system's behavior by applying manufacturing-specific theorems, corollaries and lemmas. A law-based description enables to model production mathematically and understand upfront their dynamics in terms of WIP generation, lead-times, exit-rates, and on-time delivery performance. While simulation alone only allows to explore the optimum solution, the development of a theory allows to gain knowledge. This improves the learning of the "e;physics"e; of manufacturing systems and contributes to a solid production's understanding and a clear and cognitive problem determination that leads to a thorough mental capture for mastering a systematic design of such highly complex systems.
