Abstract

Traditionally, food and drink have been used as a means of survival. In recent years, as technology has advanced and our quality of life has improved, we have begun to seek out better food - not just for the sake of the food itself, but to consume wisely, considering not only the ingredients but also the manufacturing process. Companies that used to simply produce and deliver products now need to provide services such as quality, promptness, and information, especially when it comes to quality control and safety, and quality management, which are directly related to the lives and safety of consumers. Many companies are introducing quality management systems to provide quality that meets the needs of customers and the market. With the development of information technology, quality inspection methods are becoming more diverse and sophisticated. However, the risk of defects occurring in the process still exists. In this paper, when a process fails due to an unknown cause, the analog/digital data of that process is selected and compared with normal cases. At that time, the analog/digital data of that process is selected and compared with normal and abnormal cases. Then, multiple regression analysis is used to describe the process of finding the failure point.
