Process capability indices have been used in the manufacturing industry to provide quantitative measures on process potential and performance. The formulae for these indices are easy to understand and straightforward to apply. But, since sample data must be collected in order to calculate these...

Reliability engineers must not only consider the consumption of energy, capital and material resources, but also seek more economic means of completing experiments effectively. This study derives formulae for computing ratios of expected type‐II censoring times and expected complete sampling...

Introduces a conditional repetitive group sampling plan. The OC and ASN functions are derived by GERT approach. The present development would be a valuable addition to the literature and a useful device to quality control practitioners and also to quality control engineers and plan designers in...

Presents a compact table yielding the parameters of a single sampling scheme. The table is compatible with the structure of MIL‐STD‐105D and the switching procedure incorporated in this scheme is relatively simpler than that of MIL‐STD‐105D. The basis for the construction of the table is...

Describes and discusses a series of researches specifically designed for analysis by sequential techniques — these were aimed at investigating the relationship between price, and customer preference, for a consumer durable article. Defines sequential analysis as a technique concerned with a...
