Asweexploredtextbooks andsources to support this course, we quickly learned that none existed. Hence, we determined that a text in modeling and simulation with applications to global events would serve not only our students’ needs, but the needs of manyengineering, science,andsocialsciencemajorswhowanttoexplore various methods of researching and representing the international events that shape the world in which we live. Modeling and simulation (M&S) as its own discipline has a number of modeling domains in its toolbox. Students with backgrounds in M&S are no doubt familiar with system dynamics, game theory, agent-based modeling, and social network modeling. Students with liberal arts back- grounds, such as in international studies, political science, history, and sociology, are accustomed to traditional social science methods of mod- eling, such as statistical modeling, formal modeling (game theory), and agent-based modeling. It did not take long for us to recognize that cou- pling these disciplines and their methods of investigation would facilitate an interdisciplinary approach to discovery and communication using the common ground between social scientists and engineers and scientists: modeling and simulation. It is important to note, however, that engineering students approach modeling and simulation from a very different perspective than do stu- dentsofinternationalstudies,politicalscience,andsociology.Engineering majorsareabletodrawontheirmathematicalbackgroundandengineering trainingformodeldevelopment,andfromtheircomputerscienceskillsfor visualization(communication). Socialsciencestudentsengageinvigorous qualitative assessment as they explore “what happened.” Understandably, social science students model those data without the skill-set of the engi- neer and the sophistication of an engineering model. The engineering student, on the other hand, may not fully appreciate the complexity of xi xii PREFACE human behavior and social network analysis as uncovered in the quali- tative research conducted by a student trained in the liberal arts. Hence, students with social science backgrounds would be well served to acquire skills that enable them to better analyze events that shape our world. Stu- dents with engineering and science backgrounds may already possess the skills necessary to model, simulate, and visualize; however, they would benefit by applying those skills to real-world events that affect our lives. Many universities have realized that modeling and simulation has become an important tool in understanding and even solving numerous and diverse problems. These institutions have begun to offer introductory and application courses in this field to acquaint their students with the foundational concepts that will help them employ modeling and simulation in their various disciplines. This book provides an orientation to the theory and applications of modeling and simulation in the realm of social science, with an emphasis on international studies, political science, history, and sociology. It is designed to provide an understanding of historical and contemporary global events and to represent those events in a scientific format. Attention is focused on (1) understanding the event with an eye to gathering empirical data to construct a model, an abstract representation of the event; (2) understanding how to construct a model; (3) understanding what model would best facilitate the representation of the data; and (4) understanding how to analyze, verify, and validate the model. The text is appropriate for students of all disciplines, but will be of special interest to students observing international affairs because it intro- ducesglobaleventsthatallofusshouldunderstand. Theintentistwofold: (1) to expose students to events in political history that have placed us in the environment in which we now live, and (2) to encourage students to explore other ways to understand and discuss that environment. To students we offer a concise look at the key concepts in the field of modeling and simulation. Although modeling and simulation neces- sarily entails mathematical representations and computer programs, the authors endeavored to highlight these concepts so that non-engineering and non-science students could understand the modeling and simulation concepts covered in the book.

In Chapter 1, Modeling and Simulation: What, When, and Why, we provide a brief history of modeling and simulation, list the many uses or applications of modeling and simulation, and speak to the advantages and disadvan- tages of using models in problem solving.
