A COMPARISON OF RELIABILITY IN COMPUTER SYSTEMS UTILIZING DUPLEX AND POLYMORPHIC CONCEPTS

Abstract

The reliability of duplex and polymorphic computers is discussed. Within the limits of the study assumption, it was found that: (1) the polymorphic type of computer configuration is more reliable than the equivalent duplex when both types are using equally reliable functional units, and (2) the polymorphic computer will cost less than an equivalent duplex when both systems are designed to the same level of reliability.
