Abstract

In production processes is the time of examination is a random variable whose distribution probabilistic particular, might be gamma or the Weibull or exponential distribution or other, under the assumption that a n-time examination (t) of the product follows the distribution of gamma with parameters (θ, γ) will be in this research defining plan preview Necessary to examine the product (n, c) given that the sample size consists of (n = g .r) (The number of groups that will be scanned (g) and size of each group (r)) either (c) is the number of units defective accepted in the sample and that these plans Will be determined according to the probability that both producer and consumer risk and the possibility of rejection of good product and the possibility of accepting bad product, respectively.Based sampling plan that will be determined on the ratio of the average real-time inspection to achieve (μ) of the units produced, to a specific value (μ_0) by the researcher and to give default values for the parameters for the distribution of gamma (γ = 2,4) and (a = 1,2, 3) The values of consumer risk (β = 0.25,0.10) and (α = 0.01,0.02,0.05).And adopted the special tabulations can Qrat landmarks plan preview them directly.
