Recently some critical papers have initiated a discussion on pros and cons of standard sampling by variables (sampling by
measurement). This discussion demonstrates the need for clarification by a sound stochastic model of statistical lot inspection.
On the basis of such a model, variables sampling for lot proportion nonconforming and attributes sampling can be compared
in terms of the theory of statistical hypothesis testing. This comparison refutes the well-known dogma of “same protection
at lower sample size with variables plans”. Sampling by measurement for lot means, however, emerges as a perfectly valid method
of statistical lot inspection. 相似文献

Investigations on acceptance sampling have attached rather few importance to defects inspection. For modern quality control,
both the steadily increasing complexity of products and the need for differentiated cost calculation involve a clear demand
for economic defects sampling in its practically most relevant form: lot-by-lot single sampling plans, where the OC (lot OC)
is considered as a function of lot sizeN, sample sizen, acceptance numberc, number of defects in the lotK. Starting from an appropriate lot OC function, the present paper develops an economic cost and control model and an economic
objective function for single defects sampling plans by adapting theα-optimal sampling scheme, introduced by E. von Collani for defectives inspection, to the purposes of defects inspection. A
simple and accurate approximation ofα-optimal defects plans is derived by means of a Poisson approximation of the lot OC function. 相似文献

Investigations on acceptance sampling have attached rather few attention to defects inspection. As to sampling models and
the corresponding operating characteristic (OC) function of single defects sampling plans, generally only typeB (process model) has been considered: sampling from a production process where the OC is conceived as a function of sample
sizen, acceptance numberc, and process average number of defects per itemλ. For modern quality control, both the steadily increasing complexity of products and the need for differentiated cost calculation
involve a clear demand for defects sampling in its practically most relevant form: lot-by-lot single sampling plans, where
the OC (typeA, lot OC) is considered as a function of lot sizeN, sample sizen, acceptance numberc, number of defects in the lotK. The present paper develops two lot OC functions from suitable assumptions on the arrangements of the total numberK of defects over theN elements of the lot. Limiting theorems on these OC functions are used to justify to some extent the customary assumption
that the Poisson process OC can serve as an approximation for typeA. The dependence of the OC functions on sample sizen, acceptance numberc, total number of defects in the lotK is described by simple formulae. 相似文献

Since 1996, the Department of Defense-USA has adopted MIL-STD-1916 (Military Standard-1916) sampling plans instead of the traditional MIL-STD-105E (Military Standard-105E) sampling plans. MIL-STD-1916 emphasizes on an effective prevention-based strategy quality system. Its attributes sampling plans are based on “zero accept one reject” as criteria of judgment. In this paper, the lot sizes are regrouped from original 11 groups into 18 new groups such that 100% inspection and sampling plan could be clearly separated. The relationship between fraction nonconforming and probability of acceptance for each verification level (VL) and lot size is investigated. The acceptable quality level (AQL) and rejectabe quality level (RQL) for each VL and lot size are also investigated. The results of this research provide user friendly tables as guidance for both supplier and customer. 相似文献

In outsourcing situations involving manufacturing and assembly, the sampling of units produced is important since in many
situations not all of the units can be tested. Destructive sampling, which commonly occurs in the assembly and manufacturing
industry, is a form of sampling where all units produced cannot be tested since the parts are destructively tested. In this
situation, sampling techniques are used to determine if an entire lot should be accepted or rejected based on the sampling
results. The traditional sampling techniques include single or classical sampling, double sampling, multiple sampling, skip-lot
sampling, chain sampling and MIL-STD-105E. The purpose of this paper is to develop a sophisticated technique that monitors
quality at a lower cost than traditional methods yet has similar monitoring characteristics in situations where quality is
high and tests are destructive. The proposed technique, Destructive Sampling Method for High Quality production processes
(DSM-HQ), is based on a cost function, which balances the costs of sampling versus the costs of finding a defect on the field.
DSM-HQ assumes to have a Poisson process defect pattern and uses an Empirical Bayesian analysis to allow the researcher to
include prior knowledge. 相似文献
