Abstract

In attributes sampling acceptance plan the decision to
accept or to reject the lot can be made, by using sampling plan
obtained by minimizing the average total expected cost, under
assumption that the distribution of lot quality is a mixed
Binomial or mixed Poisson, i.e. each lot is produced by a
process under Binomial or Poisson control, but the average
process varies from lot to lot according to a frequency
distribution which assumed to be differentiable in the
neighborhood of the break- even value. The purpose of this
paper is to derive the parameter of optimal sampling plan (n, c,
ï´), which represent the sample size (n) and acceptance number
(c) and time interval (ï´) between failures, by minimizing the
expected value of total cost function. We use the method of
multivariate search technique and partial enumeration
procedure. Some auxiliary examples are given.
