Overview: |
System
reliability and availability have always been very important
to ground systems. Over the past two decades, software has
grown dramatically in complexity in such systems, and architectures
have evolved from centralized mainframe-based systems to
LAN-based client server systems and now to service oriented
architectures. At the same time, hardware has become more
reliable and as a result, software failures are becoming
the dominant cause of system failures. Unfortunately, reliability
modeling and analysis techniques developed in the 1960s have
not kept pace with this trend.
This talk will describe approaches
for assessment of complex distributed real time systems used
in mission critical or safety critical applications. We will
demonstrate the combined use of traditional system reliability
assessment techniques with software static and reliability
growth models to enable the prediction of whether such systems
will meet their reliability and availability requirements,
and demonstrate how such an integrated model can be used
for system level tradeoffs (e.g., redundancy vs. test time).
Successive generations of both system and software reliability
prediction methods and tools have been developed since the
early 1970s. However, these techniques assumed that the software
executed in a single module or node, and are therefore not
sufficient to address the needs of current complex systems
that that incorporate both COTS and developmental software,
COTS hardware, and Internet Wide Area Networks (WANs), all
of which contribute to system downtime. |

Biography: |
Myron Hecht is a Senior Engineering Specialist at the Aerospace Corporation
where he works on software and system reliability and system safety issues on
satellite and space programs. He has participated in the acquisition of multiple
large software intensive National Security Space systems concentrating on the
software, reliability, and safety aspects. This presentation is a result of this
experience. His research interests include architectural and software reliability,
and software fault tolerance, and he has previously worked in the domains of air
traffic control and nuclear energy. Mr. Hecht is an author of 80 publications and
holds B.S. and M.S. degrees in nuclear engineering, an M.B.A., and a J.D. degree
all from UCLA. |
