Abstract
Wald gave an approximate formula for the operating characteristic of a sequential test. Furukawa, Ohta and Kase have recently presented a design procedure for the sequential sampling inspection with given producer's and consumer's risks based on the minimal lattice paths (MLP). Their procedure is highly accurate for calculating the operating characteristic and the average total inspection of the sequential sampling plan by attributes. In this paper, we propose a new rectifying sequential inspection plan, by applying the design procedure based on the MLP to rectifying sampling plans by attributes, which has an advantage from viewpoint of the average total inspection.
