Hi friends, 
I haven't done such a simulation before and any help would be greatly appreciated. I need your guidance.

I need to simulate end to end data for Reliability/survival analysis of a Pump ,with correlation in place, that is at 'Transactional level' or at the granularity of time-minutes, where each observation is a reading captured via Pump's sensors each minute.
Once transactional data is prepared I Then need to summarise above data for reliability/ survival analysis. 

To begin with below is the transactional data format that i want prepare: 
Pump-id| Timestamp | temp | vibration | suction pressure| discharge pressure | Flow 

Above transactional data has to be prepared with below failure modes
Defects :
(1)    Cavitation – very high in frequency but low impact
(2)    Bearing Damage – very low in frequency but high impact
(3)    Worn Shaft – medium frequency but medium impact

I have used survsim package but that's not what I need here. 
Please help and guide.
