Framing and Managing Lean Organizations in the New Economy

by Darina Lepadatu, Thomas Janoski

2020 · Routledge

This book examines the dominance and significance of lean organizing in the international economy. Scholars from each discipline see lean production as positive or negative; the book blends theory with practice by sorting out these different academic views and revealing how lean is implemented in different ways. The first part synthesizes academic research from a range of disciplines—including, engineering, sociology, and management—to present the reader with an integrated understanding of the benefits and drawbacks of lean management. The second part links this theory to practice, with a set of case studies from companies like Apple, Google, Nike, Toyota, and Walmart that demonstrate how lean is implemented in a variety of settings. The book concludes with three models, explaining how Toyotism, Nikefication with offshoring, and Waltonism provide full or less complete models of lean production. It clearly presents the positive and negative aspects of lean and insights into the culture of lean organizations. With its rich interdisciplinary approach, Framing and Managing Lean Organizations in the New Economy will benefit researchers and students across a range of classes from management, sociology, and public policy to engineering.

Adaptive Feed-Forward Control of Low Frequency Interior Noise

by Thomas Kletschkowski

2011 · Springer Science & Business Media

This book presents a mechatronic approach to Active Noise Control (ANC). It describes the required elements of system theory, engineering acoustics, electroacoustics and adaptive signal processing in a comprehensive, consistent and systematic manner using a unified notation. Furthermore, it includes a design methodology for ANC-systems, explains its application and describes tools to be used for ANC-system design. From the research point of view, the book presents new approaches to sound source localization in weakly damped interiors. One is based on the inverse finite element method, the other is based on a sound intensity probe with an active free field. Furthermore, a prototype of an ANC-system able to reach the physical limits of local (feed-forward) ANC is described. This is one example for applied research in ANC-system design. Other examples are given for (i) local ANC in a semi-enclosed subspace of an aircraft cargo hold and (ii) for the combination of audio entertainment with ANC.
