Chain sampling plan for variables inspection

Abstract

This paper extends the concept of chain sampling to variables inspection when the standard deviation of the normally distributed characteristic is known. A discussion of the shape of the known sigma single-sampling variables plan is given. The chain sampling plan for variables inspection will be useful when testing is costly or destructive.

A new mixed chain sampling plan based on the process capability index for product acceptance

“…The operating procedure and characteristics of the attributes ChSP can be seen in Dodge (1955). Govindaraju and Balamurali (1998) extended the concept of chain sampling to variables inspection. Balamurali and Usha (2013) developed tables for the selection of optimal parameters of variables ChSP.…”

A new lot inspection procedure based on exponentially weighted moving average

“…Attribute plans are easy to implement while variable plans are more informative than attribute sampling plans. More details about variable plans can be seen in Collani (1990), Seidel (1997), Govindaraju and Kuralmani (1992), Govindaraju and Balamurali (1998), Balamurali and Jun (2006), Balamurali and Jun (2007), Tsai and Lin (2010), Klufa (2010), Vangjeli (2012), Aslam, Huang, Jun, Ahmad, and Rasool (2011), Aslam et al (2012), Wang and Tsai (2012) and Aslam, Wu, Azam, and Jun (2013).…”

A lots-dependent variables sampling plan considering supplier’s process loss and buyer’s stipulated specifications requirement

“…To overcome this disadvantage, Govindaraju and Balamurali (1998) expanded the operational notion of attributes chain sampling to the variables inspection strategy. Later, Balamurali and Jun (2007) broadened the concept of attributes MDS into variables MDS and assumed a normally distributed quality characteristic with a unilateral specification limit.…”
