## Elements of System-Dynamic Simulation: A Textbook with ExercisesThis book assumes that the reader does not have much knowledge of mathematics. Therefore, the essentials of the necessary mathematics is gradually introduced. It emphasizes the practical applications of the system-dynamics concept by providing working problems and solutions. Experience shows that the concepts and principles of system-dynamics are fairly easy to learn but are difficult to convert into the language of system-dynamics. Examples and problems are taken from different disciplines like physics, chemistry, process control, biology, ecology, hydrology, environmental health science, economics, social science etc. The problems are so treated that readers from other disciplines can solve them with system-dynamics. The advantage of this approach is that the reader becomes aware of the way problems from various disciplines can be described and explained analogously. This is important for an interdisciplinary approach to the problems. |
