Abstract: In previous papers, a new adaptive sampling method was presented for application in the economic statistical control context. By means of an economic model, an optimal solution can be defined. The results obtained previously indicate that the approach might be more useful than both the fixed-sampling-intervals and variable-sampling-intervals approaches. In this paper, further results together with new simple approximations are presented and analyzed. In the light of previous results, the main conclusion is that the new approach seems to be useful for practical purposes as it is comparatively simple and also allows for some reductions in terms of the total expected costs per cycle.
