Abstract: This paper presents an approach of hypothetical reasoning for action decision of Automated Guided Vehicle (AGV) in Autonomous Decentralised Flexible Manufacturing Systems (AD-FMS). The AD-FMS is characterised as being online, in real-time mode and of a short-term nature that responds to frequent changing of the production order. The decentralised control in AD-FMS enables to solve dynamically some typical task of production system without using a fixed centralised control system. We adopt a hypothetical reasoning approach that will decide the conceivable next action from the competition hypothesis. Simulation results show that the efficiency of AGV in AD-FMS increased.

Keywords: automated guided vehicles; AGVs; flexible manufacturing systems; decentralised FMS; hypothetical reasoning; decision making; decentralised control; simulation; autonomous FMS.
