摘要

田口损失函数方法用于评估与小型货车后轮对准问题有关的过程改进经济学，该问题假定可以通过应用自动化在装配线上进行纠正。提出了客户视角，其中主要数据是从实际案例研究中获得的。估算相关的工厂成本是为了说明目的，以便考虑合理的资本支出，以尽量减少对社会(即制造商和客户)的损失。两者的损失是根据三种选择来计算的:什么都不做;执行100%的产品检验和返工缺陷;实施过程改进自动化。一个案例是为工厂设备的资本投资的一个新的类别的理由，即，增加对客户的测量价值。

Factory automation economic justification by Taguchi method: automotive example

Taguchi loss function methodology is used to evaluate process improvement economics relating to a minivan rear wheel alignment problem that is presumed to be correctable on the assembly line by application of automation. A customer perspective is presented wherein principal data are obtained from an actual case study. Pertinent factory costs are estimated for illustrative purposes to allow the consideration of a capital expenditure that is justified to minimize loss to society, i.e. the manufacturer and customers. Loss for both is calculated for three alternatives: do nothing; implement 100% product inspection and rework defectives; and implement process improvement automation. A case is made for a new category of justification for capital investments in factory equipment, namely, to increase measured value to customers.<>
