>> 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.
