Abstract
To be healthy is extremely important both in terms of reducing national medical expenses, productivity of companies and organizations, and quality of life（ QOL） of individual life. We propose to apply online quality engineering method to create guidelines for health management for that purpose. There is a variety of concrete methods even if saying online quality engineering in a bite. In this issue, we will discuss the method of periodic maintenance for optimization of dental visit period, the method of examination design for examination of profit/loss of paying optional examination at medical examination, and the method of feed forward control using T method of MT system as a prediction method for weight management aimed at getting out of the preliminary group of metabolic syndrome. While options of other methods are considered, we clarified the reason why the method was selected and how to set each parameter in the calculation formula. It made it possible to create guidelines in each case. Along with that, we can show part of the range of application range of online quality engineering, and it is expected that it will lead to the activation of future applications.
