The papers within this volume reflect the multidisciplinary approach taken by the workshop to the development and improvement of existing production control theories and practices as applied to the process industry. Subjects covered include production planning, quality control and assurance, operational control and maintenance strategy. The development of this area is seen by those at the workshop as only being achieved by various groups working together rather than in isolation, so that the overall aim of production control is not lost in too much detail. This volume will provide the reader with essential information on new initiatives in the process industry with regard to production control.
