针对IEC1123所建议的截尾序贯检验存在未能使平均试验次数达到最少等不足之处,在对最优截尾序贯检验进行精确定义的基础上,通过在截尾序贯样本空间建立序关系,采取逐点优化的方式得到截尾序贯检验的最优化方案.计算结果表明,新方法与IEC1123所建议的截尾序贯抽样方案及序贯网图检验(SMT)相比,无论是在序贯检验截尾值的控制,还是在减少检验的平均试验次数等方面,都有十分明显的改进.
針對IEC1123所建議的截尾序貫檢驗存在未能使平均試驗次數達到最少等不足之處,在對最優截尾序貫檢驗進行精確定義的基礎上,通過在截尾序貫樣本空間建立序關繫,採取逐點優化的方式得到截尾序貫檢驗的最優化方案.計算結果錶明,新方法與IEC1123所建議的截尾序貫抽樣方案及序貫網圖檢驗(SMT)相比,無論是在序貫檢驗截尾值的控製,還是在減少檢驗的平均試驗次數等方麵,都有十分明顯的改進.

@@@@This paper proposes a new sampling plan, the sample space ordering method, to compute the optimum truncated sequential test in order to overcome the disadvantages of the widely use sequential sampling methods that IEC1123 has presented. The main ideal of this new method is to establish an order at the truncated sequential sample space, and optimize point by point to arrive the optimal truncated sequential test. The paper presents in detail how to realize the new plan, and shows that this new plan has most powerful to control the sample number and least average sample number comparing with the methods which IEC1123 and SMT have proposed.
