Supplying high-quality products to markets is an
essential mission of manufacturers. The recent
globalization of mass production has led to lower
prices for consumers and potentially higher profit
for manufacturers. However, inadequate quality
management severely increases quality costs as well
as negatively impacting on a company s brand image.
Traditional statistical quality control has not
provided any definite guidelines for dealing with
sporadically-occurring assembly defects. This book
introduces newly developed metrics for assembly
complexity. A process-based complexity factor is
derived from a time standard defined for a set of
assembly tasks, and shows satisfactory correlation
with defect rates for each assembly step. A design-
based complexity factor is derived from the DFA
method for rating ease-of-assembly to augment
factors not captured by the process-based complexity
factor. Integrating these complexity factors not
only alerts product designers of deficiencies in the
original design concept, but also enables
manufacturing engineers to take proactive measures
for potential highly error-prone assembly processes.
