Application of Sequential Testing to Motor Vehicle Emission Certification
为机动车排放测试设计了一种基于经济考量的序贯检验方案，能处理多重属性、随机性和误分类问题，并应用于EPA认证程序，回顾性分析表明可节省资源且不显著降低性能。
A new structure for economically-based sequential inspection plans is developed for use in motor vehicle emission testing. The structure allows for multiple attributes, multiple sources of randomness, misclassification of inspected items, and adjustment of cost parameters to produce desirable classical properties. Specific sequential plans are developed for the Environmental Protection Agency's motor vehicle certification program and are applied retrospectively to vehicles tested in the past. The use of such plans in the past could have saved resources while resulting in no significant degradation in performance. Both the structure and computational methods used have potential application to other sampling inspection problems.
