With today's speedy developments in computational power, simulation methods are becoming more popular by the day. The area of application is tremendous and the importance is even greater. From the perspective of financial engineering and mathematical finance, simulation methods have greatly contributed to various calculations, especially in risk management. There are quite a number of books out there that cover simulation from the theoretical as well as an applied point of view. This one concentrates on developing the theory, but with the help of detailed examples and narrative explanations. It does not resemble a hard core mathematical book.

The authors suggest that introductory knowledge of probability and statistics should suffice to understand the text. Nevertheless, they decided to include a chapter covering these two topics and more. Having the prerequisites suggested by the authors might not be enough, however, to understand the first chapter. It would be more comfortable to have at least some knowledge of stochastic processes and Markov chains. Then this chapter would be great companion to fill in the gaps. For more advanced readers it should be a nice reminder.

Naturally, this chapter is followed by one on random numbers, random number generation, and stochastic process generation. The main theorems and algorithms are provided with good explanations. Examples are provided after each method is presented. They are quite detailed: some calculations are provided along with illustrations.

The text does not follow a theorem-proof-algorithm structure but rather the authors concentrate on narrative presentation of the methods. With chapter 3 the reader will get the first glimpse of where and how simulation is used today. The motivation provided is excellent, giving reader numerous examples to think about. Also, general steps of computer modeling and validation are presented in words. The whole chapter feels like it is one big example because of the great detail of presentation. One can really get a picture of what is done. Everything is explained as a step-by-step process.

Chapter 4 deals with statistical analysis of discrete-event systems. Now that we know how to construct them, we need the tools to analyze the output properly. The authors discuss the evaluation of estimators and confidence intervals for both static and dynamic simulation models. Various well-known examples are given in detail. Variance reduction techniques are discussed in a separate chapter with plenty of examples and narrative explanations. MCMC methods are presented using detailed examples. Only the most necessary theoretical concepts are given. For an applied approach this is not a bad way to go. Algorithms are given along with detailed explanations. Appendices provide additional theoretical concepts.

The book could serve well for an upper undergraduate or a (lower) graduate course on simulation. There are plenty of exercises provided at the end of each chapter. Most of the problems are of an applied nature. Of course there are also some proof problems, but not too many; the concentration is on understanding the concepts presented. Given the structure of the problems they are likely to contribute significantly to the learning process. The inclusion of some MATLAB code will also give students an edge while studying the book. One additional thing that would be beneficial is a list of possible projects.

Overall the book is nicely written and the additions to the book from the 1^{st} edition certainly make it more attractive to a wider audience. I would recommend it to students and practitioners with appropriate background. I think practitioners would be fonder of it than students, as they need fast explanations that are actually understandable without a PhD in mathematics.
