I've got a simulation that runs by 4 hours and later another 4 hours. There's a processor's breakdown for 1 hour. I need the source stops sending elements, just for 1 hour, to the queue because the processor cannot do its work, I want my system to resume after the breakdown for another 4 hours and not reset it. The source works with an inter-arrival time according to a normal distribution with mean 3.4 min and sd 0.5 min. Could someone help me, please?
