Abstract : A major problem with present fleet tactical computer programs is the failures that occur because of software faults caused by intermittent transient errors. Presented are measures that should be taken to prevent the generation of these transients, and possible steps for the detection and the correction of faults caused by these transients. Examples are drawn from the practices used in the SAFEGUARD, AEGIS, and STAR computer system programs. The paper describes some of the causes of the program degradation and requirements for future activities to overcome these problems. Some specific examples are shown to illustrate corrective measures that could be taken. The applicability of protective redundancy to computer programs is established. (Author)
