Linear optimisation is concerned with the solution of maximisation and minimisation problems that are described by linear functions and linear constraints. In particular, linear programming problems, assignment problems and transportation problems. Problems of this kind arise in areas such as engineering (e.g. optimising aggregate blends), economics (e.g. linear economic models), financial management (e.g. trend channels) and business (e.g. product mix, manpower allocation and transport management). This book is intended to introduce this highly applicable branch of applied mathematics to undergraduate and postgraduate students studying mathematics, engineering, operational research and business.
