Abstract

In this article, a group acceptance sampling plan (GASP) for lot resubmitting is developed to ensure quality of the product lifetime assuming that the product’s lifetime follows the half logistic distribution. The parameters of the GASP are determined by satifying the specified producer’s and consumer’s risks according to the experiment termination time and the number of testers. A comparison between this proposed group sampling and the ordinary group sampling plan is discussed. This proposed plan is justified with an illustration.

Highlights

The single acceptance sampling is the most popularly used one because it is simple for practical implementation
Due to the fact that it could take long experimental time to observe the complete lifetime of a high reliability item, the life test must be ended within a specified schedule and such life test is called a truncated life test
Single acceptance sampling plans under a truncated life test have been investigated in the past few decades by Gupta and Groll (1961) [13], Gupta (1962) [14], Govindaraju and Ganesalingam (1997) [12], Fertig and Mann (1980) [11], Kantam and Rosaiah (1998) [15], Kantam et al (2001) [16], Baklizi (2003) [7], Wu and Tsai (2005) [33], Rosaiah and Kantam (2005) [20], Tsai and Wu (2006) [32], Balakrishnan et al (2007) [9], Aslam (2007) [1], Rao et al (2008) [22], Aslam and Kantam (2008) [2], Rao et al (2009) [23], Lio et al (2010) [18], Rao et al (2010) [25], Rao (2011) [26]

Introduction

The single acceptance sampling is the most popularly used one because it is simple for practical implementation. Due to the fact that it could take long experimental time to observe the complete lifetime of a high reliability item, the life test must be ended within a specified schedule and such life test is called a truncated life test. Single acceptance sampling plans under a truncated life test have been investigated in the past few decades by Gupta and Groll (1961) [13], Gupta (1962) [14], Govindaraju and Ganesalingam (1997) [12], Fertig and Mann (1980) [11], Kantam and Rosaiah (1998) [15], Kantam et al (2001) [16], Baklizi (2003) [7], Wu and Tsai (2005) [33], Rosaiah and Kantam (2005) [20], Tsai and Wu (2006) [32], Balakrishnan et al (2007) [9], Aslam (2007) [1], Rao et al (2008) [22], Aslam and Kantam (2008) [2], Rao et al (2009) [23], Lio et al (2010) [18], Rao et al (2010) [25], Rao (2011) [26]
