Operational research, which may be regarded as the scientific approach to management, is widely-used to assist decision-making in government, business and industry. The main concepts and techniques are presented in this book, as well as an explanation of the essential mathematical formulae and methods. The text contains more than 20 BASIC computer programmes and includes 56 examples and solutions and a total of 123 problems for practice. Although primarily aimed at engineering and science students, the text would be appropriate to any discipline which includes management studies.
