RELIABILITY OF UNATTENDED ELECTRONIC EQUIPMENT.

Abstract

The following rule summarizes the average performance observed for various classes of military electronic systems: the mean time to first failure of a unit (MTTF) is inversely proportional to its complexity. Depending on the environment in which the equipment operates, the following relationships obtain: MTTF (hours) x N (number of electronic components)= 2.5 x 10 to the 4th power airborne environment, 1.25 x 10 to the 5th power shipborne and ground mobile environment, 1 x 10 to the 6th power laboratory environment. Unattended electronic systems such as have been proposed for ocean surveillance give rise to an entirely new order of problems. Since their operating lifetimes must be as much as 100 times longer than those of their manned counterparts, the accepted standards of ''high reliability'' are completely inadequate. (Author)
