Note—Optimal Inspection Policy in Sequential Screening
研究序贯筛选中的最优检验策略，将过程建模为贝叶斯最优停止问题，并开发了一种比现有算法更高效的后向递归算法。
Under sequential screening, a production lot is inspected item-by-item; the decision is made after inspecting each item whether to inspect another item or to reject the remainder of the lot; and thus uninspected items are never accepted. This screening process is a special case of the sequential sampling considered in Wortham and Wilson (1971). The process is formulated as an optimal stopping problem using a Bayesian approach. Based on an analysis of the structural properties of the optimal policy, a backward-recursive optimal algorithm, which is more efficient than the existing algorithm for optimal sequential sampling, is developed.
