How Often Should a Machine be Inspected?

Abstract

This article provides the answer to the question asked in the title when certain simple conditions apply, and so improves the approximate solutions given by previous writers. The assumptions are: the machine either works perfectly or not at all; there is a constant probability of random failure; the cost of inspection and of restoring the machine to as‐new condition are both fixed: failure can only be detected by inspection.
