The theory and practice of optimization as a tool for successful decision-making when designing new products and processes: While the focus is on the formulation of optimization problems, also attention is given to solution methods, software implementation, and analysis and interpretation of solutions.The book helps the chemical engineer in formulation, solving and analyzing different classes of optimization problems (LP\'s, NLP\'s MIP\'s) at different scales (from individual equipment and product up to plant and supply chain). This book is an excellent guide and companion for undergraduate, graduate students as well as professional practitioners.
