Simultaneous Acceptance Control Charts for Independent Processes
研究了当多个独立过程或产品特性需同时符合规格限时，如何设计验收控制图，并给出了最优样本量和控制限的确定方法，包括不同抽样成本下的计算。
Acceptance control charts establish control limits based on specification limits for processes where the natural dispersion is small and the mean may be permitted to vary. This paper deals with acceptance control charts where two or more independent processes creating a product, or two or more characteristics of a product, are controlled for simultaneous conformity to specification limits or standards. Optimum sample sizes and control limits for each process are determined even when sampling costs are different. For two processes a direct computational formula is developed; otherwise, non‐linear optimization is indicated.
