摘　　要：假设望小和望大质量特性分别服从对数正态分布和威布尔分布,分别用田口质量损失函数和线性质量损失函数测度质量损失,构建了望小和望大特性的质量投资模型。数值计算和灵敏度分析表明不同的损失函数对质量投资决策的影响趋势基本相同,但决策结果有时会产生明显差异。依据本文的研究,管理者可以估计质量投资的效果,调整投资决策以达到最大收益。Assuming that the quality characteristic obeys log-normal or Weibull distributions,we develop a model on quality investment,which includes the quadratic quality loss function and the linear quality loss function for a one-sided specification limit.We find that the quality loss function will effect on quality investment.Based on this research,the management can evaluate the affect of quality investment and change their quality investment to generate significant financial return.
