A hands-on teaching and reference text for chemical engineers In writing this book the authors' have focused exclusively on the vast majority of chemical engineering students who need a basic understanding of practical process control for their industrial careers. Traditionally process control has been taught using non-intuitive and highly mathematical techniques (Laplace and frequency-domain techniques). Aside from being difficult to master in a one-semester course, the traditional approach is of limited use for more complex process control problems encountered in the chemical processing industries. When designing and analyzing multi-loop control systems today, industry practitioners employ both steady-state and dynamic simulation-based methodologies. These 'real time' methods have now all but replaced the traditional approach. A Real Time Approach to Process Control provides the student with both a theoretical and practical introduction to this increasingly important approach. Assuming no prior knowledge of the subject, this text introduces all of the applied fundamentals of process control from instrumentation to process dynamics, PID loops and tuning, to distillation, multi-loop and plant-wide control. In addition, students come away with a working knowledge of the three most popular dynamic simulation packages. The text carefully balances theory and practice by offering students readings and lecture materials along with hands-on workshops that provide a 'virtual' process on which to experiment and from which to learn modern, real time control strategy development. Features: * The first and only textbook to use a completely real time approach. * Gives students the opportunity to understand and use HYSYS software. * Carefully designed workshops (tutorials) have been included to allow students to practice and apply the theory. * Includes many worked examples and student problems.

An uncomfortable observation in the Shift Logs and Process Control records of most aluminum smelting plants is that process control failures, large and small, happen every day. Although only a small fraction of these failures give rise to catastrophic events, the difference between a disaster we read about and a failure which, although expensive, has no irreversible consequences, is only chance. Control for Aluminum Production and Other Processing Industries exemplifies new control thinking fused with an understanding of process variability, and how to diagnose abnormalities and their causes in aluminum production plants. Many real life examples in the book demonstrate the importance of human behavior and a scientific, questioning approach in the control of a technologically complex process. Written from the perspective of production staff and management, the book also gives readers a view into the human aspects of accidents and their analogy with failures in control of production. Production plants regularly experience more control failures than successes and staff must continuously strive to establish stability and control of their process. Through on-the-job experiences of the authors and their industry colleagues, the control experiences described in this book provide readers with a foundation for building their own robust control rationale and a framework for avoidance of plant control problems.

Bahnbrechend. Inspirierend. Eines der faszinierendsten Bücher zur Organisationsentwicklung des letzten Jahrzehnts. Dies ist ein sehr wichtiges Buch, bedeutsam in vielerlei Hinsicht: Sowohl angesichts der bahnbrechenden Forschungsergebnisse, Einsichten, Ratschläge und Empfehlungen, die es enthält, als auch aufgrund der genauso wichtigen Fragen und Herausforderungen, auf die es hinweist.“ Ken Wilber aus dem Nachwort „Die programmatische Aufforderung ‚Reinventing Organizations‘ mündet in einem Organisationsmodell, das Strukturen wie Praktiken nach neuartigen, evolutionär-integralen Prinzipien ausrichtet. Im Ergebnis steht die Erkenntnis, dass das Leben und Arbeiten in Organisationen, ebenso wie deren Leistungsbeiträge für die Gesellschaft, radikal zum Positiven verändert werden können. Aber hierzu muss nicht zuletzt die Führung eine fortgeschrittene Entwicklungsebene erreichen.“ Prof. Dr. Jürgen Weibler, Autor des Standardwerkes „Personalführung“ „Das Buch gibt Hoffnung und ganz konkrete Hilfe zur Lösung der Probleme, die wir an der Schwelle von der Postmoderne zu einem neuen Zeitalter erleben, in denen die traditionellen oder modernen Organisationsformen den Anforderungen und Bedürfnissen der Menschen nicht mehr gerecht werden.“ Eine Leserin auf Amazon.com Frederic Laloux hat mit Reinventing Organizations das Grundlagenbuch für die integrale Organisationsentwicklung verfasst. Die Breite sowie Tiefe seiner Analyse und Beschreibung – ganzheitlich, selbstorganisierend und sinnerfüllend operierender Unternehmen – ist einzigartig. Das erste Kapitel des Buches gibt einen Überblick über die historische Entwicklung von Organisationsparadigmen, bevor im zweiten Kapitel Strukturen, die Praxis und die Kultur von Organisationen, die ein erfüllendes und selbstbestimmtes Handeln der Menschen ermöglichen, anhand von ausgewählten Beispielen vorgestellt werden. Auf die Bedingungen, Hindernisse sowie Herausforderungen bei der Entwicklung dieser evolutionären Organisationen wird in Kapitel 3 eingegangen. Hier entwirft Frederic Laloux einen Leitfaden für den Weg hin zu einer ganzheitlich orientierten und sinnstiftenden Organisation. Frederic Laloux ist auch aufgrund dieses Buches ein mittlerweile gefragter Berater und Coach für Führungskräfte, die nach fundamental neuen Wegen der Organisation eines Unternehmens suchen. Er war Associate Partner bei McKinsey & Company und hält einen MBA vom INSEAD.

Success in the continuous process industries depends upon the ability to adapt to the demands of global supply chains in real-time. Thus, process plants must be designed to be easily reconfigured as and when necessary. “A Distributed Coordination Approach to Reconfigurable Process Control” presents research that addresses this issue, via developing a new distributed framework that will enable the building of a process control system that is capable of reconfigurability. This framework views the process as a set of readily-integrated, modular process elements, which operate relatively independently and are each supported by a degree of stand-alone decision-making capability. The rationale and benefits of moving towards the new approach is demonstrated by means of a worked example of a real process plant. The research will also help end-users to gain an understanding of the economic aspects of material flows across their plants, and the ways in which their processes can be integrated across the enterprise.

Scheiß auf positives Denken sagt Mark Manson. Die ungeschönte Perspektive ist ihm lieber. Wenn etwas scheiße ist, dann ist es das eben. Und wenn man etwas nicht kann, dann sollte man dazu stehen. Nicht jeder kann in allem außergewöhnlich sein und das ist gut so. Wenn man seine Grenzen akzeptiert, findet man die Stärke, die man braucht. Denn es gibt so viele Dinge, auf die man im Gegenzug scheißen kann. Man muss nur herausfinden, welche das sind und wie man sie sich richtig am Arsch vorbeigehen lässt. So kann man sich dann auf die eigenen Stärken und die wichtigen Dinge besinnen und hat mehr Zeit, sein Potential gänzlich auszuschöpfen. Die subtile Kunst des darauf Scheißens verbindet unterhaltsame Geschichten und schonungslosen Humor mit hilfreichen Tipps für ein entspannteres und besseres Leben. Damit man seine Energie für sinnvolleres verwendet als für Dinge, die einem egal sein können.

This book describes how manufacturing enterprises, by reinforcing their existing monitoring and control of manufacturing processes, can successfully face the ever-increasing pressure from internal and external environments to maintain their competitive advantage. Numerous performance measurement systems have been elaborated to satisfy these requirements, stressing the importance of financial and operational metrics. It also highlights the fact that research on generating and linking financial and operational metrics, especially in real-time, has not garnered sufficient attention to date. The book follows an approach that integrates enterprises across different levels and departments. By computing and linking the financial and operational metrics in real-time, the book demonstrates how to provide a comprehensive view of an entire enterprise.

This book deals with transportation processes denoted as the Real-time Distribution of Perishable Goods (RDOPG). The book presents three contributions that are made to the field of transportation. First, a model considering the minimization of customer inconvenience is formulated. Second, a pro-active real-time control approach is proposed. Stochastic knowledge is generated from past request information by a new forecasting approach and is used in the pro-active approach to guide vehicles to request-likely areas before real requests arrive there. Various computational results are presented to show that in many cases the pro-active approach is able to achieve significantly improved results. Moreover, a measure for determining the structural quality of request data sets is also proposed. The third contribution of this book is a method that is presented for considering driver inconvenience aspects which arise from vehicle en-route diversion activities. Specifically, this method makes it possible to restrict the number of performed vehicle en-route diversion activities.​

Human and animal vision systems have been driven by the pressures of evolution to become capable of perceiving and reacting to their environments as close to instantaneously as possible. Casting such a goal of reactive vision into the framework of existing technology necessitates an artificial system capable of operating continuously, selecting and integrating information from an environment within stringent time delays. The YAP (Vision As Process) project embarked upon the study and development of techniques with this aim in mind. Since its conception in 1989, the project has successfully moved into its second phase, YAP II, using the integrated system developed in its predecessor as a basis. During the first phase of the work the "vision as a process paradigm" was realised through the construction of flexible stereo heads and controllable stereo mounts integrated in a skeleton system (SA V A) demonstrating continuous real-time operation. It is the work of this fundamental period in the V AP story that this book aptly documents. Through its achievements, the consortium has contributed to building a strong scientific base for the future development of continuously operating machine vision systems, and has always underlined the importance of not just solving problems of purely theoretical interest but of tackling real-world scenarios. Indeed the project members should now be well poised to contribute (and take advantage of) industrial applications such as navigation and process control, and already the commercialisation of controllable heads is underway.

Consumers today expect extremely realistic imagery generated in real time for interactive applications such as computer games, virtual prototyping, and scientific visualisation. However, the increasing demands for fidelity coupled with rapid advances in hardware architecture pose a challenge: how do you find optimal, sustainable solutions to accommodate both speed of rendering and quality? Real-Time Rendering: Computer Graphics with Control Engineering presents a novel framework for solving the perennial challenge of resource allocation and the trade-off between quality and speed in interactive computer graphics rendering. Conventional approaches are mainly based on heuristics and algorithms, are largely application specific, and offer fluctuating performance, particularly as applications become more complex. The solution proposed by the authors draws on powerful concepts from control engineering to address these shortcomings. Expanding the horizon of real-time rendering techniques, this book: Explains how control systems work with real-time computer graphics Proposes a data-driven modelling approach that more accurately represents the system behaviour of the rendering process Develops a control system strategy for linear and non-linear models using proportional, integral, derivative (PID) and fuzzy control techniques Uses real-world data from rendering applications in proof-of-concept experiments Compares the proposed solution to existing techniques Provides practical details on implementation, including references to tools and source code This pioneering work takes a major step forward by applying control theory in the context of a computer graphics system. Promoting cross-disciplinary research, it offers guidance for anyone who wants to develop more advanced solutions for real-time computer graphics rendering.
