- Abstract:
- A calibration and an adjustment of measurement device are keys to realize a metrological traceability. (Calibration means just checking without adjustment in this paper.) Although the traditional online quality engineering can be one of applications to determine calibration interval and adjustment limit in terms of cost, approximations used in the traditional quality engineering are too rough to take stochastic behaviour of a bias in a device into consideration. In this paper, we propose an optimum calibration interval and an optimum adjustment limit for a measurement device with a bias in accordance with Brownian dynamics concerning a long-term cost.
