A novel adaptive multiple dependent state sampling plan (AMDSSP) was designed to inspect products from a continuous manufacturing process under the accelerated life test (ALT) using both double (DSP) and (MDSSP) concepts. Under conditions, lifetime of product follows Weibull distribution with known shape parameter, while scale parameter can be determined acceleration factor (AF). The Arrhenius ...

In this article, a novel acceptance-sampling plan is proposed to decide whether to accept or reject a receiving batch of items. In this plan, the items in the receiving batch are inspected until a nonconforming item is found. When the sum of two consecutive values of the number of conforming items between two successive nonconforming items falls underneath of a lower control threshold, the batc...

In this paper, a group acceptance sampling plan is developed for a truncated life test when the lifetime of an item follows the Marshall-Olkin extended exponential distribution. The minimum number of groups required for a given group size and the acceptance number is determined when the consumer’s risk and the test termination time are specified. The operating characteristic values, according t...

Sampling plans, systems and schemes are used to accept/reject the lots when inspecting a series of lots. A sampling system is a grouping of two or more sampling plans with specified rules for switching between the plans for selecting the lots of finished products. Quick Switching System (QSS) is used to make accept or reject decisions when inspecting a series of lots. Quick Switching System req...

In this paper, a hybrid group acceptance sampling plan is developed for a truncated life test when the lifetime of an item follows log-logistic distribution. The minimum number of testers and acceptance number are determined when the consumer’s risk and the test termination time and group size are specified. The operating characteristic values according to various quality levels are found and t...
