| 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. 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. |
