Time truncated two sided modified chain sampling plans for exponential distribution

Abstract

In this paper, Two Sided Modified Chain Sampling Plans (TSMChSP) for Exponential distribution is presented. The decision of acceptance lot can be made by ensuring no defects in both preceding and succeeding samples. The design parameters such as the minimum sample size and operating characteristic values are calculated to ensure the consumer’s risk at a specified quality level. The main purpose of this article is to produce the TSMChSP for Exponential distributions. An example is provided for illustrative purpose.Then, the article moving on further to compare the performances of TSMChSP and TSChSP, based on two criteria, which are the number of minimum sample size, and the probability of lot acceptance,. The article concluded that, the TSMChSP has a better performance compared to the TSChSP in both criteria.
