Book Description
MORE THAN ONE MILLION COPIES IN PRINT • “One of the seminal management books of the past seventy-five years.”—Harvard Business Review This revised edition of the bestselling classic is based on fifteen years of experience in putting Peter Senge’s ideas into practice. As Senge makes clear, in the long run the only sustainable competitive advantage is your organization’s ability to learn faster than the competition. The leadership stories demonstrate the many ways that the core ideas of the Fifth Discipline, many of which seemed radical when first published, have become deeply integrated into people’s ways of seeing the world and their managerial practices. Senge describes how companies can rid themselves of the learning blocks that threaten their productivity and success by adopting the strategies of learning organizations, in which new and expansive patterns of thinking are nurtured, collective aspiration is set free, and people are continually learning how to create the results they truly desire. Mastering the disciplines Senge outlines in the book will: • Reignite the spark of genuine learning driven by people focused on what truly matters to them • Bridge teamwork into macrocreativity • Free you of confining assumptions and mindsets • Teach you to see the forest and the trees • End the struggle between work and personal time This updated edition contains more than one hundred pages of new material based on interviews with dozens of practitioners at companies such as BP, Unilever, Intel, Ford, HP, and Saudi Aramco and organizations such as Roca, Oxfam, and The World Bank.

Book Description
Simulation Modeling and Analysis with Arena is a highly readable textbook which treats the essentials of the Monte Carlo discrete-event simulation methodology, and does so in the context of a popular Arena simulation environment. It treats simulation modeling as an in-vitro laboratory that facilitates the understanding of complex systems and experimentation with what-if scenarios in order to estimate their performance metrics. The book contains chapters on the simulation modeling methodology and the underpinnings of discrete-event systems, as well as the relevant underlying probability, statistics, stochastic processes, input analysis, model validation and output analysis. All simulation-related concepts are illustrated in numerous Arena examples, encompassing production lines, manufacturing and inventory systems, transportation systems, and computer information systems in networked settings. - Introduces the concept of discrete event Monte Carlo simulation, the most commonly used methodology for modeling and analysis of complex systems - Covers essential workings of the popular animated simulation language, ARENA, including set-up, design parameters, input data, and output analysis, along with a wide variety of sample model applications from production lines to transportation systems - Reviews elements of statistics, probability, and stochastic processes relevant to simulation modeling

Book Description
As the complexity of our world increases systems thinking is emerging as a critical factor for success, and even survival. How then can people become skilled systems thinkers? The most effective learning experiences combine experience with reflection, theory with practice. Traditionally, theory was taught in school and university, and experience was gained in life outside those walls. But in the world of complex dynamic systems such as a business, society, or ecosystem, everyday experience fails because the time horizon and scope of the systems is so vast-we never experience the majority of the effects of our decisions. And without relevant experience, theory is uninteresting to students. The old ways of learning fail. When experiments in the real world are impossible, simulation becomes the main way we can learn effectively about the dynamics of complex systems. For this reason I'm pleased to introduce Juan Martin Garcia's book 'Theory and Practical Exercises of System Dynamics'. Juan combines theory and practice, experience and opportunities for reflection, so that newcomers to the field can learn for themselves how complex dynamic systems work. The examples span a range of important economic and social issues, from the aging of the population in developed economies to the course of contagious diseases to the accumulation of pollutants in the environment; everyone will find some examples here of direct personal interest. The modeling exercises guide the learner through the process of building a working simulation; students will not only learn about the issues addressed, and in the use of state of the art simulation software, but will develop skill in the modeling process. Juan has written a delightful first introduction to the field of system dynamics and complexity, and provides a much-needed addition to the literature available. John D.

System Dynamics finds its main applications in the complex and ill-defined environments. System Dynamics is radically different from other techniques applied to the construction of models of socioeconomic systems, such as econometrics based on a behavioral approach. The basic objective of System Dynamics is to understand the structure that causes the behavior of the system. System Dynamics allows the construction of models after a careful analysis of the elements of the system. This book provides a clear and orderly vision of how to build a simulation model with System Dynamics.The System Dynamics finds its main applications in the complex and ill-defined environments, where the decisions of the human being intervene. The point of view of the System Dynamics is radically different from that of other techniques applied to the construction of models of socioeconomic systems, such as econometrics based on a behavioral approach. The basic objective of System Dynamics is to understand the structural causes that cause the behavior of the system.The System Dynamics allows the construction of models after a careful analysis of the elements of the system. This analysis allows to extract the internal logic of the model, and with it to try an understanding of the long-term evolution of the system.There is an extensive bibliography on System Dynamics, this book provides a clear and orderly vision of how to build a simulation model with this technique.

Book Description
Since the publication of the first edition in 1982, the goal of Simulation Modeling and Analysis has always been to provide a comprehensive, state-of-the-art, and technically correct treatment of all important aspects of a simulation study. The book strives to make this material understandable by the use of intuition and numerous figures, examples, and problems. It is equally well suited for use in university courses, simulation practice, and self study. The book is widely regarded as the “bible” of simulation and now has more than 100,000 copies in print. The book can serve as the primary text for a variety of courses; for example: • A first course in simulation at the junior, senior, or beginning-graduate-student level in engineering, manufacturing, business, or computer science (Chaps. 1 through 4, and parts of Chaps. 5 through 9). At the end of such a course, the students will be prepared to carry out complete and effective simulation studies, and to take advanced simulation courses. • A second course in simulation for graduate students in any of the above disciplines (most of Chaps. 5 through 12). After completing this course, the student should be familiar with the more advanced methodological issues involved in a simulation study, and should be prepared to understand and conduct simulation research. • An introduction to simulation as part of a general course in operations research or management science (part of Chaps. 1, 3, 5, 6, and 9).

Book Description
The classic book on systems thinking—with more than half a million copies sold worldwide! "This is a fabulous book... This book opened my mind and reshaped the way I think about investing."—Forbes "Thinking in Systems is required reading for anyone hoping to run a successful company, community, or country. Learning how to think in systems is now part of change-agent literacy. And this is the best book of its kind."—Hunter Lovins In the years following her role as the lead author of the international bestseller, Limits to Growth—the first book to show the consequences of unchecked growth on a finite planet—Donella Meadows remained a pioneer of environmental and social analysis until her untimely death in 2001. Thinking in Systems is a concise and crucial book offering insight for problem solving on scales ranging from the personal to the global. Edited by the Sustainability Institute’s Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world, showing readers how to develop the systems-thinking skills that thought leaders across the globe consider critical for 21st-century life. Some of the biggest problems facing the world—war, hunger, poverty, and environmental degradation—are essentially system failures. They cannot be solved by fixing one piece in isolation from the others, because even seemingly minor details have enormous power to undermine the best efforts of too-narrow thinking. While readers will learn the conceptual tools and methods of systems thinking, the heart of the book is grander than methodology. Donella Meadows was known as much for nurturing positive outcomes as she was for delving into the science behind global dilemmas. She reminds readers to pay attention to what is important, not just what is quantifiable, to stay humble, and to stay a learner. In a world growing ever more complicated, crowded, and interdependent, Thinking in Systems helps readers avoid confusion and helplessness, the first step toward finding proactive and effective solutions.
