Concepts for inventory verification in critical facilities

“…It is shown in Ref. 24 that, if the detection probability is the same for diverting equal amounts in large or small removals, the optimum diversion strategy against the combined attributes- No. of Inventory Periods…”

“…Formulae to calculate sample sizes are given for the number of items t o be measured. The formulae take into account the possibility t h a t the scatter of amount values below the crossover may be increased in order t o make the bias detection more d i f f i c u l t Hough, Schneider, Stewart, Jaech, and Bennett, 1974).…”
