The main problem is the scheduling of AGV in realtime scheduling optimization of the FMS logistics system. This paper presents two forms of AGV scheduling strategy, one is based on genetic algorithms (GA) of the AGV scheduling, the other is based on particle swarm optimization (PSO) of the AGV scheduling. It verifies the model and scheduling optimization ideas by example based on the developed simulation program and the scheduling module. According to the running of the realdata of assumption, the processing time of the FMS is shortened by realtime scheduling optimization. 
