Extending Koo and Case's model (1990) for the case of a single assignable cause to allow for the second occurrence of an assignable cause following the first occurrence and the probability of the assignable causes following exponential distribution, the process-failure mechanism having a fixed...

This paper considered newsboy-type products with a normally distributed demand, and defined a product's profitability as the probability of achieving the target profit under optimal ordering condition. In order to determine whether the product is already unworthy of being ordered (or...

Acceptance sampling plans are practical tools for quality control applications, which involve quality contracting on product orders between the vendor and the buyer. Those sampling plans provide the vendor and the buyer rules for lot sentencing while meeting their preset requirements on product...

Acceptance sampling plans are practical tools for quality assurance applications involving quality contract on product orders. The sampling plans provide the vendor and buyer decision rules for product acceptance to meet the preset product quality requirement. As the rapid advancement of...

Process capability indices (PCIs), Cp, Ca, Cpk, Cpm, and Cpmk have been developed in certain manufacturing industry as capability measures based on various criteria, including process consistency, process departure from a target, process yield, and process loss. It is noted in certain recent...

Capability measure for processes yield with single characteristic has been investigated extensively, but is still comparatively neglected for processes with multiple characteristics. Wu and Pearn [Wu, C.W., Pearn, W.L., 2005. Measuring manufacturing capability for couplers and wavelength...
