This article presents research results on multi-agent manufacturing control in holonic manufacturing systems. After a short introduction to holonic systems, the PROSA reference architecture is discussed. PROSA has gained already significant maturity through its application to a number of test cases. Next, manufacturing control based on emergent behavior and ant-like communication and coordination are discussed. This paragraph on emergent control discusses early results of research efforts that aim at a complete manufacturing control solution coping with change and disturbances. Finally, the role of agents in manufacturing control is addressed.
