In the decade that has passed since the initial publication of Production Systems, many time-tested techniques for planning, analysis and control remain unchanged; however, most have benefited from new technology and recent developments. This updated version presents the newest concepts and explores the current problems facing production analysts, including inflation, limited resources, preservation, computer-aided design and manufacturing, and productivity improvement. The subjects and techniques covered provide a substantial introduction to production concepts. Diverse topics are integrated into one conceptual framework that makes the material easier to comprehend and the interrelationships more visible. The topics are presented in a non-technical fashion that practitioners and aspiring practitioners will find clear and comprehensible.
