“…This is called the AQL. Considered Fallahnezhad and Qazvini [9] the control of raw materials, semi-finished products or finished products as a dimension of quality assurance. They defined it as acceptance sampling when the control is carried out with the aim of accepting or rejecting a product by adhering to certain standards.…”

“…This method is a scalable cluster analysis algorithm designed to process very large data sets. The most important features of this algorithm are; i) it can be applied in large data sets, ii) it can process categorical and continuous variables, iii) the items that do not fit with the obtained sets can be removed when desired Tkaczynski [9], and iv) it can automatically determine the most appropriate number of clusters [12]. In this method, it is important that the measurements of the variables included in clustering in clustering algorithms are categorical or metric.…”

“…This risk is further increased by the excellent progress in production technology and the stringent control demands of customers. For this reason, the number of samples must be large in order to capture the real lot quality, especially in enterprises producing million units [9]. In this study, two different AQL approaches were created for large-volume samples.…”

In this study, a proposal has been developed aimed at the establishment of an AQL sampling plan in enterprises that produce lots type with a high number of unit products and group packaging. In the developed model, two different sampling approaches were tested comparatively, based on the two-stage cluster sampling method approach. The application of the proposed model was carried out in a high-volume lots type bolt factory. In the first approach, the boxes (clusters) to be sampled were determined based on the number of boxes in the determined lot. In the second stage, the sample amount was determined by calculating the AQL over the unit number of products in the randomly selected boxes and an equal amount of sample was taken from the selected boxes. In the second approach, the boxes to be sampled were determined again based on the number of boxes in the determined lot, and the sample amount to be taken from the determined boxes was calculated based on the number of unit products in the whole lot. Trials were made for the acceptance quality limits of 2.5, 4 and 6.5 for both approaches and the acceptance/rejection statuses were compared. Bu çalışmada, birim ürün adedi yüksek ve grup paketlemeli parti tipi üretim yapan işletmelerde AQL örnekleme planı oluşturulmasına yönelik bir öneri geliştirilmiştir. Geliştirilen modelde, iki aşamalı küme örnekleme yöntemi yaklaşımı temel alınarak iki farklı numune alma yaklaşımı karşılaştırmalı olarak test edilmiştir. Önerilen modelin uygulaması yüksek hacimli parti tipi üretim yapan bir cıvata fabrikasında gerçekleştirilmiştir. Birinci yaklaşımda, belirlenen partideki kutu adedi baz alınarak örneklem alınacak kutular (kümeler) belirlenmiştir. İkinci aşamada ise, rassal olarak seçilen kutulardaki birim ürün adedi üzerinden AQL hesaplaması yapılarak numune miktarı belirlenmiş ve seçilen kutulardan eşit miktarda örnek alınmıştır. İkinci yaklaşımda ise, yine belirlenen partideki kutu adedi baz alınarak örneklem alınacak kutular belirlenmiş olup belirlenen kutulardan alınacak numune miktarı partinin tamamındaki birim ürün adedi baz alınarak hesaplanmıştır. Her iki yaklaşım için 2.5, 4 ve 6.5 kabul kalite sınırları için denemeler yapılmış ve kabul/red durumları karşılaştırılmıştır.

Purpose The purpose of this paper is to design a modified chain sampling plan for assuring the product percentile life where the lifetime follows Weibull or generalized exponential distributions (GEDs). In order to reduce the cost of inspection when implementing the proposed modified chain sampling plan, it is also considered the economic aspect of designing of proposed plan in this paper. Design/methodology/approach The authors have designed the proposed plan on the basis of two points on the operating characteristic (OC) curve approach. The optimization problem is used to determine the plan parameters of the proposed plan so that the specified values of producer’s risk and consumer’s risk are satisfied simultaneously. Findings The results we have obtained, confirm that the proposed plan will be very effective in reducing the sample size rather than other existing sampling plans. The OC curves of proposed plan, chain sampling plan and zero acceptance number single sampling plan show that the performance of proposed plan in discriminating the good and poor quality lots is better than other two plans. In this paper, it is proved that the value of number of preceding lots required for current lot disposition plays an important role. Originality/value The proposed modified chain sampling plan for assuring the percentile lifetime of the products under Weibull or GEDs is not available in the literature. The proposed plan can be used in all the manufacturing industries to assure the product percentile lifetime with minimum sample size as well as minimum cost.

Recently, economic and Bayesian aspects on the sampling plans have been investigated by some of the authors (see, for example, Fallahnezhad and Babadi, 2015; Fallahnezhad and Qazvini, 2016).…”

Skip-lot sampling plans have been widely used in industries to reduce the inspection efforts on products that have an excellent quality history. These skip-lot sampling schemes are economically advantageous and useful to minimize the cost of the inspection of the final lots. Also, the skip-lot concept is sound and useful in the design of sampling plans. In this paper, we propose a designing methodology to determine the optimal parameters of a skip-lot sampling plan of type SkSP-2 when the quality characteristic under study follows a normal distribution. The optimal plan parameters are determined to minimize the average sample number subject to satisfying the producer’s and consumer’s risks simultaneously at the acceptable and limiting quality levels, respectively. An optimization problem is formulated in order to construct tables for determining the optimal parameters of the proposed sampling plan for both known and unknown standard deviation cases and the results are compared with the variables single sampling plans.
