[Liqichao]

Hello,
Here is the sentence: Functional hazard analysis to ensure all possible safety hazards in the system were identified, satisfactorily addressed and mitigated.

can I understand 'address' as investigation or learning?

can use 'decreased' to take off 'mitigated'?

thank you for your answers

.
'Addressed'-- 'attended to; a solution attempted'
'Decreased'-- a poor but valid synonym for 'mitigated'.

Addressed here means dealt with. Mitigated means reduced or prevented or eliminated -- any means that lessen the risks. In another words, you use the functional hazard analysis to identify the hazards, deal with them and make the system (or airplane) safe (reducing or eliminating or preventing the hazards).
