汽车制造中的主要成本因素之一是车身和其他部件的喷漆，如机翼或引擎盖。令人惊讶的是，这幅画可能比身体本身还贵。从这个角度来看，很明显，汽车制造商需要仔细观察喷漆过程，以避免与预期结果有任何偏差。特别是对于金属颜色，其闪光是基于微观的铝颗粒，客户往往对汽车不同部件的光反射差异非常敏感。下面的研究是与汽车行业的一个合作伙伴密切合作进行的，结合了经典测试和非参数平滑技术来检测汽车涂装过程中的趋势。本研究采用t检验法、Mann-Kendall法、Cox-Stuart法和变点检验法。基于借鉴非参数平滑的重采样方法，通过仿真研究了合适的参数设置和所提出的检验的性质。分析的目的是找到一种可靠的技术解决方案，避免任何来自人的方面的交互。
One of the major cost factors in car manufacturing is the painting of body and other parts such as wing or bonnet. Surprisingly, the painting may be even more expensive than the body itself. From this point of view it is clear that car manufacturers need to observe the painting process carefully to avoid any deviations from the desired result. Especially for metallic colors where the shining is based on microscopic aluminium particles, customers tend to be very sensitive towards a difference in the light reflection of different parts of the car. The following study, carried out in close cooperation with a partner from car industry, combines classical tests and nonparametric smoothing techniques to detect trends in the process of car painting. The localized versions motivated by t-test, Mann-Kendall, Cox-Stuart and a change point test are employed in this study. Suitable parameter settings and the properties of the proposed tests are studied by simulations based on resampling methods borrowed from nonparametric smoothing. The aim of the analysis is to find a reliable technical solution which avoids any interaction from a human side.
