基于无穷范数空间距离的计数型函数响应优化方法研究

A Study of the Optimization Method for Count-Type Functional Responses Based on the Infinity-Norm Distance

计数型函数响应在制造过程中广泛存在。然而,已有研究大多针对的是连续型函数响应的优化。本文基于拟合值向量的无穷范数空间距离指标,结合满意度函数法,提出一元和多元计数型函数响应优化方法。仿真试验结果表明,本文提出的拟合值向量无穷范数空间距离指标更精准地反映函数响应向量之间真实距离。该方法应用于某公司液晶显示屏模组柔性电路板与玻璃基板压接工艺参数改进,降低了产品不合格率。

Count-type functional responses widely exist in manufacturing processes.However,most existing researches are focused on the optimization of continuous functional responses.An optimization method is proposed for count-type functional responses by combining the infinity-norm distance index for the vectors of the fitted values with the desirability function method.The simulation results show that the proposed infinity-norm distance index for fitted value vectors reflects the true distance more accurately and less variably.This method is applied to the analysis of the bonding process for flexible printed circuits and glass substrates in a TFT-LCD module manufacturing company.The unqualified rate of products is effectively reduced.
