The text is intended to serve as a general introduction to the area of mathematical modeling, aimed at advanced undergraduate or beginning graduate students in mathematics and closely related fields. Formal prerequisites consist of the usual freshman-sophomore sequence in mathematics, including one-variable calculus, multivariable calculus, linear algebra, and differential equations. Prior exposure to computing and probability and statistics is useful, but is not required.

The numerical algorithms in the text are presented in the form of pseudocode. Some instructors will prefer to have students implement the algorithms on their own. On the other hand, if students are not going to be required to program, we want to make it easy for instructors to provide them with appropriate software. All of the algorithms in the text have been implemented on a variety of computer platforms that can be made available to users of this textbook at no additional cost. To obtain a copy, click on the following to download files for MAPLE (also contains classroom demonstration files), MATHEMATICA (also contains classroom demonstration files) , MatLAB (courtesy of Professor Radu Cascaval, Department of Mathematics, University of Colorado at Colorado Springs), Maxima (a free computer algebra system), R (for a more sophisticated R package, see this one by Hao Li), BASIC, FORTRAN, DERIVE, Microsoft Excel, Quattro Pro, and Microsoft Works. Some additional files are available for LINDO, MINITAB. If you are willing to share your own implementation with other instructors and students, please contact the author. With your permission, we will distribute to others through this web page at no charge.

Unlike some textbooks that focus on one kind of mathematical model, this book covers the broad spectrum of modeling problems, from optimization to dynamical systems to stochastic processes. Each chapter in this book is followed by a set of challenging exercises. Following the exercises in each chapter is a list of suggestions for further reading. This list includes references to a number of UMAP modules in applied mathematics which are relevant to the material in the chapter. UMAP modules can provide interesting supplements to the material in the text, or extra credit projects. All of the UMAP modules are available at a nominal cost from COMAP, Inc., Suite 210, 57 Bedford Street, Lexington MA 02137.

The text contains numerous computer-generated graphs, along with instruction on the appropriate use of graphing utilities in mathematics. Computer algebra systems are used extensively in those chapters where significant algebraic calculation is required. The text includes actual computer output from the computer algebra systems MAPLE and MATHEMATICA, the popular linear programming package LINDO, and the commonly used statistical package MINITAB.
