This book aims to illustrate with practical examples the applications of linear optimization techniques. It is written in simple and easy to understand language and has put together a useful and comprehensive set of worked examples based on real life problems. The topics include linear programming, integer programming and goal programming. The book can be used by teachers, taught-course students and research students of engineering and business/management disciplines. It is, however, not suitable for students of pure mathematics as its emphasis is on applications rather than theories.
