本文介绍日本近年开发的三种企业计量管理新方法:1.波动度的经济评价——损失函数;2.计量器具的精度评价——SN 比;3.选择现场使用的计量器具的正交试验设计法。同时,还介绍了计量器具的校准及校准后的误差,自动机过程测量最佳间隔的确定以及计量器具最佳校准周期和最佳校准量的确定。它们应用了田口型质量管理方法(美国统称 Takuchi 法)。
This article describes three new methods of measurement management developed in Japan in recent years: 1. Economic evaluation of volatility - loss function; 2. Precision evaluation of measuring instruments - SN ratio; 3. Orthogonal test of measuring instruments used on-site Design Law. At the same time, also introduced the calibration of measuring instruments and calibration errors, the determination of the optimal interval of automatic process measurement and the determination of the best calibration cycle and the best calibration of measuring instruments. They applied Taguchi quality management methods (the United States generally referred to as Takuchi method).
