田口线内质量工程学探析

引言 线内质量工程学（On—line Quality Engineering），又称制造阶段的质量工程学，是日本著名质量管理专家田口玄一博士针对生产现场的工序管理和产品管理提出的系列理论和方法，其核心是基于田口质量观的质量损失函数。

For the past five decades, Taguchi led what has been called the ＂ quality revolution＂ in manufacturing around the world. This paper focuses on Taguchi＇s On-line Quality Engineering, explains the major content, on-line process management and on-line product management, after systematically analyzing his basic theories, Taguchi＇s quality view, loss function and process tolerance. In addition, it presents a detailed application case to illustrate the powerful function of Taguchi＇s On-line Quality Engineering in economically improving product quality.
