Computation-Based Reliability Analysis [PDF]

open access: yesIEEE Transactions on Computers, 1976
A reliability analysis method for computing systems is considered in which the underlying criteria for "success" are based on the computations the system must perform in the use environment. Beginning with a general model of a "computer with faults," intermediate concepts of a "tolerance relation" and an "environment space" are introduced which account
