This book presents a fresh, new approach to systems analysis and modeling with a systems science flavor that stimulates systems thinking. After introducing systems modeling principles, the ensuing wide selection of examples aptly illustrate that anything which changes over time can be modeled as a system. Each example begins with a knowledge base that displays relevant information obtained from systems analysis. The diversity of examples clearly establishes a new protocol for synthesizing systems models.* Macro-to-micro, top-down approach* Multidisciplinary examples* Incorporation of human knowledge to synthesise a systems model* Clear and concise systems delimitation* Complex systems using simple mathematics* "Exact" reproduction of historical data plus model generated secondary data* Systems simulation via systems models
