MONITERING MEASUREMENT SYSTEM

• THREE STEPS WARNING• 1) Alarm = 70% allowable front calculation each state of work

-inform everybody who concern-meeting to fix the ploblem

2) Alert = 85% allowable front calculation each state of work- fix the ploblem-meeting result of fixing

3) Action = 90% allowable front calculation each state of work- stop work- fix the ploblem -meeting result of fixing
