关于序贯抽样检验

On sequential sample test

利用Wald的序贯概率比检验中接收产品时对应的批检验数 :n1 (0 ,c1 1 ) ,n2 (1 ,c1 2 ) ,… ,nk (k - 1 ,c1k) ,… ,设计出一种改进型序贯检验 (其中当c1t <s时 (t=1 ,… ,s) ,取c1t =c1t;当c1t≥s时 ,取c1t =s) :n1 (0 ,c1 1 ) ,n2 (1 ,c1 2 ) ,… ,ns (s - 1 ,s)。证明了当次品率较小 (p≤p0 )时 ,改进型序贯检验的平均抽检个数N (p)与序贯概率比检验的N(p)比较接近 ,但抽检周期要小得多。表 1参
