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...

A sampling plan named as Multiple Dependent State Repetitive Group Sampling (MDSRGS) is introduced for a time-truncated life test given that the underlying distribution of product's lifetime Inverse Power Lomax (IPLD). The proposed developed with help two already plans (MDS and RGS). two-point approach OC function known producer's risk customer's used to determine parameters plan. An optimizati...

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...

abstract background: hypertension is the main risk factor of many diseases and the main reason of death all over the world. because the signs of hypertension are not clear, people do not feel its dangers and do not believe they are at risk. this problem makes preventing hypertension a great challenge for the health system. one factor that is related to lifestyle and is effective in preventing h...

In this paper, we develop an optimization model for the economic design of repetitive sampling plan in the presence of two markets. The process under consideration produces a product with a normally distributed quality characteristic with unknown mean and known variance. The quality characteristic has a lower specification limit. The quality of the product is controlled via lot-by-lot acceptanc...
