Bayesian theory based identification of relationship between product reliability and quality characteristics using expert's experience

Reliability is achieved throughout product development process including development and manufacturing stages. Little progress has been made in the identification of the relationship between product reliability indices and its quality characteristics, which is essential for the control of the product reliability in manufacturing stage. In this paper, we propose a method of identifying the relationship by introducing group judgment determination process in which individual judgments of experts with different weights are integrated to make final group judgment. The proposed method can be applied in various areas of manufacturing.
