The reliability of life-critical computer systems
1986
Acta Informatica
Preserved Fulltext
In order to aid the designers of life-critical, fault-tolerant computing systems, accurate and efficient methods for reliability prediction are needed. ...
Methods to analyze the effects of variations in input parameters on the resulting reliability predictions are also provided. ...
Nevertheless, the extensive reliability demands placed upon these life-critical systems (reliability >1-10 -9 ) preclude simple procedures by which we might verify that the systems possess the level of ...
