MTBF MTTR
I'm having trouble understanding the difference between MTTR and MTBF...
I am trying to model a conveyor where frequent stoppages occur on average once an hour (largely due to jams)  no information is given on the type of distribution. And the time between belt stop and belt start for the last 50 occurrences follow an erlang distribution with a location value of 0, and a scale value 0.17, shape value of 21 and random number stream 1
Then is is okay to say (using the tool box) that:
MTBF follows an exponential distribution with scale value 60
MTTR follows erlang  with the values given above
Thanks
