Abstract
In our previous paper, design procedures for double sampling attributes plans with given two points on the OC curve were presented. The design procedures were based on the least square criterion which makes the producer's and consumer s risks close to the specified values under (special) constraint of c2=c3. In this paper, we discuss a general design procedure for the double sampling plans without any special constraints. Samples sizes (n1, n2)are obtained as numerical solutions of simultaneous differential equations, and acceptance numbers (c1, c2, c3) are determined according to the inspection cost which contains the sampling cost at the second stage of inspection.
