![]() ![]() Specifically, statistics now comes before random processes to enable students understand the basic principles of probability and statistics before studying random processes. First, the chapters have been slightly rearranged. This second edition of the book differs from the first edition in a few ways. Some mathematical knowledge is assumed, especially freshman calculus and algebra. Sincemany students learn by “doing,†it is suggested that the students solve the exercises at the end of each chapter. The emphasis throughout the book is on the applications of probability, which are demonstrated through several examples that deal with real systems. ![]() It grew out of the author’s fifteen years experience developing and analyzing probabilistic models of systems in the industry as well as teaching an introductory course on probability and random processes for over ten years in two different colleges. The book is designed for juniors and seniors, but can also be used at lower graduate levels. Thus, this book differs from other books in the sense that it presents two chapters on the essentials of statistics. However, it is not necessary for the student to take a separate class on statistics since most of the prerequisites for statistics are covered in a probability course. Also, since some of the engineering problems deal with data analysis, the student should also be exposed to some knowledge of statistics. Therefore, to an engineering student the emphasis on a probability and random processes course should be on the application of probability to the solution of engineering problems. This book belongs to this group and is based on the premise that to the engineer, probability is a modeling tool. These books avoid the measure theoretic approach and rather emphasize the axioms upon which the theory is based. In the middle lies a group of books that combine probability and random processes. At the other extreme are books that combine probability with statistics without devoting enough time on the applications of probability. At one extreme are the very rigorous books that present probability from the point of view of measure theory and spend so much time proving exotic theorems. These books range widely in their coverage and depth. There are several books on probability and random processes. These include messages arriving at a switchboard customers arriving at a restaurant, movie theatre or a bank component failure in a system traffic arrival at a junction and transaction requests arriving at a server. Many systems encountered in science and engineering require an understandingof probability concepts because they possess random variations. ![]()
