Improvement of Quadratic Exponential Quality Gain–Loss Function and Optimization of Engineering Specifications

In the past, optimization of engineering specifications primarily included influence quality loss terms on product quality; however, in actual production practice, compensation quantity inevitably affects specifications. this paper, quadratic exponential and gain function was first supplemented, constructed under larger-the-better characteristic smaller-the-better characteristic; order to accurately represent change amount process control, method specification calculation given combination with hyperbolic tangent function. Finally, support dam construction acceptance assessment, model tested. The optimal coefficient obtained as 0.162, range reduced from 0.744 0.648, achieving goal.
