Abstract

A single quality characteristic of a product is typically considered on the development of economic specification limits in the recent researches. However, from the view of the customers, products are often evaluated based on more than one quality characteristics. Due to the observation, this paper will not only develop an optimum process for two quality characteristics based on bivariate exponential distributions, but also provide a sensitivity analysis for the results.
