I have just completed the JHU program in Systems Engineering. This book is the foundation for the curriculum and is a very readable, solid overview of Systems Engineering. All phases of the system life-cycle are introduced and tied together to truly illustrate the process. The book focuses on processes, the tools used will change, but good Systems Engineering will stay the same. The process to derive good requirements that are able to be implemented and tested are the same regardless of technology or field.

Nicolae Lobontiu, Associate Professor of Mechanical Engineering at the University of Alaska-Anchorage, brings his years of experience teaching classes in system dynamics, as well as the knowledge gleaned from writing four related previous texts -- Dynamics of Microelectomechanical Systems; Mechanical Design of Microresonators; Mechanics of Microelectromechanical Systems; and, Compliant Mechanism: Design of Flexure Hinges -- to produce this solid text for students entering this emerging field.
The discipline of system dynamics focuses on teaching students "how to create and analyze mathematical models of dynamic, mechanical, electrical/electromagnetic, thermal, and fluid/pneumatic systems" for the purpose of designing and then testing systems before they are actually built. While the author retains a classical approach, Lobontiu also introduces examples from compliant mechanisms and microscale devices and machines.
Consideration is given to mechanical engineering problems for junior and senior-level undergraduate students in support of mechanical, aerospace, electrical, biomedical and civil engineering courses and explores mechanism and movement in springs and joints present in "micro-machined, lithographic based devices to traditional models of microscale, fluidic, and electromechanical systems." Offers a "foundation and framework for the development of controllers applied to these dynamical systems." Includes examples and problems at the end of each chapter to familiarize readers with the modeling and dynamical systems engineers are likely to encounter in the future.
Publisher touts the text as "the first system dynamics textbook to include extensive examples from the relatively new application areas of microelectromechanical systems (MEMS) and compliant (flexible) mechanical devices," and to offer "more ancillary instructor support than any other system dynamics text."
Text is divided into eleven chapters and four appendices:
Ch. 1 Introduction; Ch 2. Mechanical Systems I; Ch. 3 Mechanical Systems II; Ch. 4 Electrical Systems; Ch. 5 Fluid and Thermal Systems; Ch. 6 The Laplace Transform; Ch. 7 Transfer Function Approach; Ch. 8 State-Space Approach; Ch. 9 Frequency Domain Approach; Ch. 10 Coupled-Field Systems; Ch. 11 Introduction to Modeling and Design of Feedback Control System.
Appendix A Solution to Linear Ordinary Homogeneous Differential Equations with Constant Coefficients; Appendix B Review of Matrix Algebra; Appendix C Essentials of MATLAB and System Dynamics-Related Toolboxes; and, Appendix D Deformations, Strains and Stresses of Flexible Mechanical Components.
Recommended for use by instructors teaching a one-semester text for engineering students; by scientists and practicing engineers wanting to better understand the fundamentals of dynamic systems, engineering modeling, vibrations, and system dynamics; and, inclusion in college and university library collections supporting mechanical, aerospace, electrical, biomedical and civil engineering courses.

Modeling the Environment, Second Edition Review

Modeling the Environment, Second Edition
Average Reviews:

(More customer reviews)
A highly readable introduction to environmental modeling. What distinguishes the book from other environmental science and environmental modeling works is its interdisciplinary treatment. In particular, the models integrate the physical world and the world of human behavior. Far too many environmental models fail to close the feedbacks between human behavior and the state of the environment, instead taking waste inputs or resource use as exogenous. This book helps students learn to model human behavior (social and economic) as an integral part of the ecological system. The models and software mean the book encourages active learning, and enable students to explore important issues on their own if they choose.

Modeling the Environment was the first textbook in an emerging field-the modeling techniques that allow managers and researchers to see in advance the consequences of actions and policies in environmental management. This new edition brings the book thoroughly up to date and reaffirms its status as the leading introductory text on the subject. System dynamics is one of the most widely known and widely used methods of modeling. The fundamental principles of this approach are demonstrated here with a wide range of examples, including geo-hydrology, population biology, epidemiology and economics. The applications demonstrate the transferability of the systems approach across disciplines, across spatial scales, and across time scales. All of the models are implemented with stock and flow software programs such as Stella and Vensim. These programs are easy and fun to learn, and they allow students to develop realistic models within the first few weeks of a college course. System dynamics has emerged as the most common approach in collaborative projects to address environmental problems. The stock and flow structures and the emphasis on feedback control provide a common language that is understood by scientists from many disciplines. Although the interdisciplinary approach described here is widely used in practice, there are few books to aid instruction. Modeling the Environment meets the urgent need for instructional materials in interdisciplinary modeling of environmental systems.

Modeling for Learning Organizations (System Dynamics Series) Review

Modeling for Learning Organizations (System Dynamics Series)
Average Reviews:

(More customer reviews)
"Modeling for Learning Organizations" builds off of the extensive experience of top professors and consultants using the SD tools to test strategies and build an understanding of firm and industry dynamics.
"Modeling" also includes a section overviewing the various simulation software packages available to modelers. Though developers like High-Performance Systems, Vensim, Pugh-Roberts, and PowerSim have made product enhancements to date, the sections from each company provide a great introduction to what is out there how each package can be applied.
The most valuable aspect of the book is probably in the case studies and methodological explorations of several authors. A number of key insights are offered as authors reflect upon the successes and shortcoming of the methods each chose to use to explore and develop models in a variety of business and public environments.
This is definitely a must have for any SD library.

Conventional wisdom says that we can learn from our errors, but errors in the business world can be prohibitively costly. To truly understand how complex business organizations function requires different tools than most managers have been given. Yet managers need methods to understand how their organization works in order to test policies, discover flaws in thinking, and find the hidden leveragepoints within the complex systems they manage. Through a system simulation, the dynamics of the whole system, not just the individual parts, becomes apparent. The outcome of current and future situations becomes possible to predict and with this information, managers can focus on the changes that need to be made.The distinguished contributors to Modeling for Learning Organizations include Jay W. Forrester, Peter Senge, and Arie De Geus. You will learn about leading applications such as:
Shell's work on modeling the oil producers.
The Management Flight Simulator, a computer-based case learning environment pioneered by John Sterman and others at MIT
The landmark Claims Learning Laboratory at Hanover Insurancecompanies.
For managers, professionals, academicians, and everyone who recognizes the profound implications of modeling, this book is an excellent resource. It offers a broad understanding of the modeling process, discusses a multitude of case studies, and provides a review of the most recent simulation software.

If you did not do modeling before and have no idea where to start from - this book is for you. It is well written and it is fun!
I had to do some modeling for a project that I have been working on. At that moment I did not have much experience in modeling, especially in modeling coupled economic and natural systems. I was looking for a good guide in ecological economic modeling but could not find anything user-friendly and interdisciplinary. I came across the web-course by Dr. Voinov and started it. The book is a great addition to the course. The web-course as well as this textbook lead you through the essential steps of model design and implementation, introduce you to main challenges and ways to resolve them, and give you some great illustrations from practical applications of ecological economics. I especially like that it provides not only the theory of modeling for ecological economics but also discusses software tools and gives you hands on experience with the exercises. I was very excited to see that the textbook is out there now. Enjoy!

Modeling is a key component to sciences from mathematics to life science, including environmental and ecological studies. By looking at the underlying concepts of the software, we can make sure that we build mathematically feasible models and that we get the most out of the data and information that we have. This book shows how models can be analyzed using simple math and software to generate meaningful qualitative descriptions of system dynamics. This book shows that even without a full analytical, mathematically rigorous analysis of the equations, there may be ways to derive some qualitative understanding of general behavior of a system. By relating some of the modeling approaches and systems theory to real world examples the book illustrates how these approaches can help understand concepts such as sustainability, peak oil, adaptive management, optimal harvest and other practical applications.* Relates modeling approaches and systems theory to real world examples * Teaches students to build mathematically feasible models and get the most of our the data and information available* Wide range of applications in hydrology, population dynamics, market cycles, sustainability theory, management, and more

Dynamic Modeling of Environmental Systems (Modeling Dynamic Systems) Review

Dynamic Modeling of Environmental Systems (Modeling Dynamic Systems)

This text is required for a course I am taking as a graduate student. The book is not worth the paper it is printed on. If you are looking for a good introduction to environmental modeling, keep looking. If you are looking for a good introduction to Stella modeling software, keep looking. This book comes with Stella 5.0, which is nearly 10 years old. The inclusion of Stella tutorials almost seems to be an afterthought, because the authors don't use the same terminology as presented in the software. Also, navigation within the book is hindered by poor organizational structure and plain black figures, tables, and text throughout. Many of the figures are drawn by hand (poorly). This topic is supposed to be dynamic and exciting, but the book is dull, disorganized, and disappointing.

The field of system dynamics was created in 1956 under the leadership of MIT Professor Jay W. Forrester to evaluate how alternative policies affect growth, stability, fluctuation, and changing behavior in corporations, cities, and countries. Forrester founded the System Dynamics Program in the Alfred P. Sloan School of Management at MIT. John Sterman is currently Director of the System Dynamics Group at MIT.
This text is a summary of the wisdom and knowledge gathered over more than twenty years of research dedicated to the study of practical methods for systems thinking and the dynamic modeling of complex systems. It is well written, easy to understand, and worthy of serious consideration.
I believe the text is destined to become a classic. It is written in a straightforward style and does not require prerequisite knowledge of higher mathematics. Indeed, in the author's words, "one of the strengths of the text is the way it presents system dynamics with a minimum of mathematical formalism. The goal is to develop the reader's intuition and conceptual understanding, without sacrificing the rigor of the scientific method." This goal is achieved well.
The text opens with a succinct and well organized description of approaches to the study of complex systems. It develops a set of principles for successful use of systems dynamics and provides well-written overviews of the Modeling Process and dynamic systems.
It covers the construction of causal loop diagrams and describes their application in a variety of business and engineering examples.
This is one of the best texts in its field for upper division undergraduate courses and graduate programs. It will be useful to many in business, engineering, and science.

Dynamic Modeling and Control of Engineering Systems Review

Dynamic Modeling and Control of Engineering Systems

A great introduction to control theory.However, it would help if you know something about differential equations. I read Ogata's book on control (over 900 pages) from cover to cover twice and still could not figure out exactly what state variables are. This book explains things very well but you do need to do the problems at the end of each chapter. The use of "free-body" diagrams is a great idea.Ogata's book is great for explaining a lot of the details but this book explains the important things in a concise but easy to understand manner. I now finally understand how to draw a system diagram by starting from the inputs for each separate system. Everything is brought together -- system diagrams,transfer functions,state variables,the purpose for LaPlace transforms,and input-output models. This is not a book about control theory and it is covered in only the last two chapters but if you are taking, or going to take, a course in control theory,read this book first. It will save you a lot of frustration and bewilderment.
