Baloui Jamkhaneh et al. (2008, 2009) have introduced a new acceptance sampling plan. In that plan the fraction of defective items is a fuzzy number. In this paper we introduce the average outgoing quality (AOQ) and average total inspect (ATI) for single sampling plan when that proportion nonconforming items is fuzzy number. We have shown that AOQ and ATI curves of the plan are like band having ...

Acceptance sampling plan is a method to make decision on either accepting or rejecting a specific lot or more generally to inspect the quality of products that can be used by different methods. Along with this, one suitable measure to improve manufacturing processes is to analyze process capability indices. These indices have many applications in production environments. In this paper, a repeti...

  In zero acceptance number sampling plans, the sample items of an incoming lot are inspected one by one. The proposed method in this research follows these rules: if the number of nonconforming items in the first sample is equal to zero, the lot is accepted but if the number of nonconforming items is equal to one, then second sample is taken and the policy of zero acceptance number would be ap...

The Importance of this paper is to account for the possibility dependence among items a sample. development new method designing sampling plans based on range quality instead point-wise description by invoking novel approach called Quality Regions. This seems be versatile and can adapted elementary production process where stipulated level advisable fix at later stage provides procedure meant i...

In this paper, a single acceptance sampling plan based on truncated life test is proposed for lifetime that follows the Zubair-Exponential (ZE) distribution. For some numbers, confidence levels, values of ratio fixed experiment time to particular mean lifetime, and minimum sample sizes required assert specified are obtained. The operating characteristic function plans, consumer's producer's ris...

This study proposes a new repetitive group sampling plan by attributes based on truncated life test under the Weibull distributions with known shape parameter. The constrained optimization problem is formulated as a nonlinear integer programming to determine the sample size and the acceptance criterion of the proposed plan. The objective function to be minimized is the average sample number, wh...

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...
