Background
Longer RestoredTime of Accident
InefficientLocation
Various Tools
1. Times of accident (include
non-quality) for 2010
reaches about 238, and
pressure of production line
is very higher
2. Restored time of accident
is too longer, and average
value is 136 minutes by
statistic in last year. Now,in Canada, the accident
recovery SOP has been
deployed(use FMA tool),
and time decreases as 40
minutes.
3. Quickly restored accident
becomes a key task for
production
1. Lacked method of location,
and inefficient for
maintenance
2. Various type of log. The
size of log is larger for
download by hand andtime is longer
3. Generous information. It is
inefficient to gather
information of accident

Accident Recovery SOPThe accident recovery SOP is guide to prevent
or recover the accident quickly for thefront, and provides technology and support.
1)Precaution and preparative operation for
accident
2) The network and guide for accident
collection tool
3) The FMA guide book
4) The emergency solution for accident, and
recover the accident by the guide
Benefit1) The time of collection of accident is
saved by using the tool
2) The efficiency of analysis for accident
is improved. FMA can display the keyinformation of accident and provide the
result of diagnose quickly.
3) The front can recover the accident based
on the emergency solution
4)The average recovery time of accident of
UMTS is decreased as 50% with last year
Application :The FMA tools has been deployed for about 53
operators. The following table is sample for
Canada, and the recovery time of accident are
