Background

Longer Restored

Time of Accident

Inefficient

Location

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 and

time is longer

3. Generous information. It is

inefficient to gather

information of accident

Accident Recovery SOP The accident recovery SOP is guide to prevent

or recover the accident quickly for the

front, 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

Benefit

1) 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 key

information 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 listed.

Download

•The download time of FMA tool in Support network, and the comparison

with the other tools

•Up to 2011-8-30，the download time of FMA has reached more than

1000 times. The tool has been widely to use by Maintenance, R&D, Test,
