Fault Tree Analysis Support Software Developed,
Allows for High Design Reliability
■ Overview ■
JATCO
Ltd. (President & CEO Takashi Hata) (hereafter referred to as “JATCO”), a
manufacturer specializing in automotive transmissions (AT/CVT), together with the
University of Tokyo (President Junichi Hamada) (hereafter “University of Tokyo”)
and the National Institute of Advanced Industrial Science and Technology (President Tamotsu Nomakuchi) (hereafter “AIST”),
through cooperation among industry, government and academia , have developed
Fault Tree Analysis (FTA) support software to achieve high reliability of
design.
FTA
is a method of analyzing failure factors by arranging the sub events that are
the factors behind the failure event in a sequential tree structure. While it
is known as an effective method for improving product quality and reliability,
creating and editing tree structures requires considerable manpower. By
reducing engineers' workloads and improving analytical quality, this software
is expected to help enhance design reliability.
Details
concerning this technology will be presented at the 21st Conference of the Japan Society of Mechanical Engineers, Design and Systems
Division held at Yamagata University from October 21 to 23, 2011.
[Main points about the software ]
- Improves the
ability to analyze a product’s failure phenomenon while
cutting engineers' workloads by 50%
- Allows for the
development of techniques for verifying (indicating/displaying faulty areas)
the validity of fault factor analyses (Uses quantity dimension technology for
failure events)
-
Helps improve product design quality
FTA
Support Software Concept
[Plans Going Forward ]
Trial
versions of the FTA support software will be distributed to JATCO’s suppliers,
and the software's functions and impact on quality improvement activities will
be evaluated and verified.
