Product quality, manufacturing cost and manufacturing time are three of the
major concerns in a manufacturing system. This study proposes a product
capability index to evaluate the quality of a multi-process product and addresses
the relationship between process yield and the product capability index. In
addition, this paper develops a time–cost index to assess manufacturing cost and
manufacturing time. The quality index and time–cost index are simultaneously
used to monitor product quality and manufacturing time on a quality and
time–cost analysis chart. The quality and time–cost analysis chart, providing
accurate information on the quality status and time–cost status for each process,
helps to initiate, effectively and efficiently, quality improvement plans to elevate
product quality and manufacturing time and manufacturing cost control for
a manufacturing system.
