After long duty night freighter crew is cleared direct to debar then the DEBAR1 arrival to cvg; but ...

Narrative:

On the debar one arrival into cincinnati airport (cvg) we were cleared to debar intersection then the debar one. Upon reaching the debar intersection we failed to intercept the 351 degree radial inbound to richmond VOR. We were notified we were off course by ATC. No other aircraft were in the area and there were no conflicts. Contributing factors were the number one FMS was deferred and we were navigating off the number 2 FMS. The pilot and copilot had both started their day the night before. 12 hours before; we were assigned the three leg outbound trip. At the end of our trip we had been on a 15 hour and 30 minute duty day. I think that night; freight operations should have greatly reduced duty days. Staying up that long on the backside of the clock greatly affects your decision making process. Even when you think you feel awake enough to do the trip.
