I understand the tribulation to be the persecution of the church (Revelation ch1 v9). The collapse of the world follows on from that (ch8 onwards).
If the plague, war, famine and consequent death continue long enough, it's just possible that we might be in the Four Horsemen period of Revelation ch6, which is the short-term collapse of the world. The Beast would arrive in the recovery period, leading the way, and THEN comes the tribulation.
It's all in my ATS Revelation threads (2012) and also in my book ("Silence in Heaven", available in all good bookstores).
