Computing system signatures through reliability functions

Jean-Luc Marichal, Pierre Mathonet
2013 Statistics and Probability Letters  
Due to a result by Owen, this index can be computed efficiently by integrating the first derivatives of the reliability function of the system along the main diagonal of the unit hypercube.  ...  We show how the signature can be computed more efficiently from the diagonal section of the reliability function via derivatives.  ...  Similarly to Owen's method, in this note we provide a way to compute the signature of the system only from the reliability function of the structure, thus avoiding Boland's formula (2) which requires the  ...

The reliability of life-critical computer systems

Robert Geist, Mark Smotherman, Kishor Trivedi, Joanne Bechta Dugan
1986 Acta Informatica  
In order to aid the designers of life-critical, fault-tolerant computing systems, accurate and efficient methods for reliability prediction are needed.  ...  We describe a model for reliability prediction which meets both requirements.  ...  Equation (8) alone will not suffice to compute system reliability.

Reliable timing systems for computer controlled accelerators

Jürgen Knott, Robert Nettleton
1986 Nuclear Instruments and Methods in Physics Research Section A : Accelerators, Spectrometers, Detectors and Associated Equipment  
Over the past decade the use of computers has set new standards for control systems of accelerators with ever increasing complexity coupled with stringent reliability criteria .  ...  Thus, for the CERN linac and LEAR (Low Energy Antiproton Ring) timing system reliability becomes a crucial factor in the sense that all components must operate practically without fault for very long periods  ...  Those requiring frequent access by the computer system are mostly housed in CAMAC crates, linked by serial CAMAC to the process computer (DEC LSI 11/73) [1] .  ...
