连续大批量空间数据质量抽样检验方案探讨

Study on sampling inspection schemes for continuous lot spatial data

摘要:

以调整型抽样方案思想为指导，利用连续批的信息量，基于历史资料反泊松推算出接收数c。同时初步探讨空间数据质量抽样检验中批量N与样本容量n之间的关系，提出了根据批量N和连续提交检查批过程平均上限值AQL确定样本容量n的计算方法。改进了连续大批量空间数据的抽样方案（N, n, c）的制定方法。最后，通过对改进算法所得抽样方案与百分比抽样方案、查表所得抽样方案进行比较，指出了改进方法的优点及其适用条件。

Abstract:

Based on empirical data, acceptance number (c) is calculated by inverse poisson. A new method is use to calculate sample size n, which uses lot size N and acceptable quality level of process average (AQL). The scheme of continuous spatial data with large lot size is designed (N, n, c). At last, the spatial data schemes, designed based on the developed algorithm, are compared with them which based on percent sampling inspection and sampling table. The results show the merits and the implementary conditions of the developed algorithm.
