Although the theory of operations management has been presented in many textbooks published in the last two decades the subject of e--enabled operations management is rather short of Iiterature which is easily accessible to students. The object of this document is to expound the subject at an "intermediate" level”. By intermediate it is not assumed that students are specialists in mathematics and statistics, but it is supposed they have a working knowledge of calculus, algebra, probability and statistics. The approach to operations management described in this book is unusual with respect to what is found in standard textbooks. Information and Communication Technologies (ICT) impact the ways firms are organised and managed, and as a consequence change the practical means used to conduct business operations.
