Productivity Machines

How productivity culture and technology became emblematic of the American economic system in pre- and postwar Germany. The concept of productivity originated in a statistical measure of output per worker or per work-hour, calculated by the US Bureau of Labor Statistics. A broader productivity culture emerged in 1920s America, as Henry Ford and others linked methods of mass production and consumption to high wages and low prices. These ideas were studied eagerly by a Germany in search of economic recovery after World War I, and, decades later, the Marshall Plan promoted productivity in its efforts to help post–World War II Europe rebuild. In Productivity Machines, Corinna Schlombs examines the transatlantic history of productivity technology and culture in the two decades before and after World War II. She argues for the interpretive flexibility of productivity: different groups viewed productivity differently at different times. Although it began as an objective measure, productivity came to be emblematic of the American economic system; post-World War II West Germany, however, adapted these ideas to its own political and economic values. Schlombs explains that West German unionists cast a doubtful eye on productivity's embrace of plant-level collective bargaining; unions fought for codetermination—the right to participate in corporate decisions. After describing German responses to US productivity, Schlombs offers an in-depth look at labor relations in one American company in Germany—that icon of corporate America, IBM. Finally, Schlombs considers the emergence of computer technology—seen by some as a new symbol of productivity but by others as the means to automate workers out of their jobs.

This book brings out the visible low hanging fruits of belt and pulley related energy losses in your daily working machine. By implementing the ‘few-months-only-as-payback-proposals’ based case studies given in this book, your industry can restore the productivity in production machines, which are mostly constant torque loads. Also, you can achieve appreciable energy savings by optimizing the speed demanded by variable torque loads like centrifugal blower, fan and pump.

This is the first book to examine the “nuts and bolts” of production processes. It proposes a truly consilient approach to modeling production processes – one that goes beyond the vague principles found in standard economics – and provides details that are consistent with the applied mechanics and engineering literature. Providing a credible analysis of some of the most pressing questions of our era, such as the productivity slowdown and the information paradox, and bridging the gap between engineering, applied physics, economics, and management science, this book is a fascinating read for anyone interested in industry, the modern economy, and how physical factors constrain productivity growth.

Since the time of the Industrial Revolution, manufacturing industries have accumulated a huge experience in creating different machines and systems for fabricating various goods, work parts, and products. All these diverse machines and systems, with different designs to solve pivoted economic problems, increased the productivity rate of manufacturing processes and generated high-quality products. In the area of productivity theory for industrial engineering, there are numerous publications that describe the fundamental approaches and the mathematical models of productivity rate for the different designs of industrial machines and systems. Known theories consider the physical productivity rate as the number of products fabricated over a given time (ASME) that is a component of economic productivity. However, known mathematical models are simplified with assumptions and not well developed analytically, which can lead to severe errors in computing the output of manufacturing systems. Modern industrial machines and systems are complex in design and in structure with serial, parallel, and serial-parallel arrangements, and any failure of any component leads to downtime of expensive production systems. For this reason, industries need a productivity theory that enables accurate predicting of the output of manufacturing systems at the preliminary stages. Key features Offers fundamental principles of productivity theory for industrial machines and systems based on mathematics, technology, design, reliability, probability, and management Presents the conceptual principles of productivity theory for industrial machines and systems Provides methods for computing productivity losses in real industrial environments Closes the gap between theory and practice for computing productivity rates of manufacturing systems Incudes a comparative analysis of productivity rates for manufacturing systems of serial, parallel, and serial-parallel arrangements Productivity Theory for Industrial Engineering presents analytical approaches and methods to define maximal productivity rates, optimal machining regimes, and optimal structure of manufacturing machines and systems based on the parameters of technological processes, structural design, reliability of mechanisms, and management systems. This book uses productivity theory for solving productivity problems and can also be used for complex approaches for sustainable improvement of production processes.

Productivity improvement means doing the same thing in a better and smarter way and continuing to work on improving the techniques for an individual or a team on the shopfloor. And this continuous improvement is the only way to achieve high profitability. Garment manufacturing involves number of operations carried out by different operators and all the activities starting from cutting, sewing till finishing are different from each other in terms of the way they are performed and the technology being used for them. So, it is always advisable to look at the working of four aspects and that are material, machine, men and method. However there are ways to build higher productive efficiencies which result in reduction in cost and bring in higher profit margin.. The book discusses different case studies from the shopfloor showing productivity improvements.

Based on analysis of owners' and managers' needs, this manual shows how to carry out training designed to improve productivity and working conditions in small and medium-sized enterprises. It encourages real shop-floor improvements based on local axperience and action learning. Forms, checklists and guides are included.; An accompanying ""Trainer's Manual"" is also available (ISBN 92-2-106410-7).
