Abstract :
Acceptance sampling is concerned with rules for deciding about the acceptance or rejection of a lot of products submitted for inspection based on the quality of the products assessed through the testing of items drawn randomly from the lot. Sampling inspection plans which are used for taking decisions about the acceptability of the product with respect to life time are called life-test sampling plans. Lifetime of the product is considered as a continuous random variable, which is modelled by a probability distribution. The literature of sampling inspection for lifetime data provides applications of various types of continuous distributions in the studies relating to the design and evaluation of life-test sampling plans. This paper presents the procedures and tables for the selection of life-test sampling plans under the conditions for application of the generalized gamma distribution. The criteria for designing life-test plans when lot quality is evaluated in terms of mean life and hazard rate are proposed.
