摘要

提出了基于伽玛失效的延期寿命试验抽样方案的图解评价与评审技术(GERT)分析方法。GERT方法被Ohta(1978)成功地用于研究一些质量控制问题。使用所谓的延迟抽样计划的想法是由于Vaerst(1980)。Shankar(1993)简要介绍了GERT方法及其在质量控制中的应用。GERT分析在当前情况下的优势是双重的。首先，该程序给出了检测系统动态的可视化图像，其次，它提供了计划的完整特征。推导了工作特性函数(OC)和平均样本数函数(ASN)的计算公式，并给出了数值说明。最后，表格已提供，以确定所需的最小样本量n，以确保一定的平均寿命或产品的质量。

GERT analysis of the deferred life test sampling plan based on gamma failure

This paper presents graphical evaluation and review technique (GERT) analysis of the deferred life test sampling plan based on gamma failure. GERT approach which has been successfully used by Ohta (1978) for studying some quality control problems. The idea of using what is known as deferred sampling plan is due to Vaerst (1980). A brief account of GERT methodology and its application in quality control has been given by Shankar (1993). The advantage of the GERT analysis in the present context is two folded. Firstly, this procedure gives a visual picture of the dynamics of the inspection system and secondly, it offers a through characterisation of the plan. The formula of operating characteristics (OC) function and average sample number (ASN) function is derived and illustrated numerically. Lastly, tables have been provided to determine the smallest sample size n necessary to assure a certain mean life or quality of the product.
