BackgroundLonger Restored Time of Accident

Inefficient LocationVarious ToolsTimes of accident (include non-quality) for 2010 reaches about 238, and pressure of production line is very higherRestored 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.Quickly restored accident becomes a key task for productionLacked method of location, and inefficient for maintenanceVarious type of log. The size of log is larger for download by hand and time is longerGenerous information. It is inefficient to gather information of accident
