ON THE SUPPLY OF SPARES TO INSURE ADEQUATE TESTING

Abstract

The problem of providing the minimum number of spares for one equipment which is to be tested for a given number of hours is considered. A sufficient number of breakdowns or replacements to exhaust a stock of spares with probability not greater than a specified level is determined. Note that unless a guarantee period (i.e. an initial period of life in which breakdown cannot occur) is known, it is not ever possible to provide enough spares to insure i.e. with probability zero that breakdowns and replacements will not exhaust the stock.
