What is it about?
The quality loss caused by degradation on quality characteristic has not been considered in most research. In this paper, the time value of money for quality loss and product degradation over time is integrated into the total cost model, and a new optimization model for the tolerance design of products with correlated characteristics is established.

Why is it important?
The discussions focus on the multivariate quality loss function as an extension of the Taguchi loss function, which is used to model quality loss due to product degradation as a continuous cash flow function under continuous compounding.
Perspectives
In this paper, the model proposed by Chou and Chang is extended to carry out tolerance design for products with correlated characteristics.
