An effective potential field approach to FMS holonic heterarchical control

This paper points out the capabilities of a heterarchical control approach, based on potential fields, to simultaneously solve the problems of dynamic allocation and routing in a real flexible manufacturing system. This paper proposes a Potential fields approach, as the key reactive mechanism to handle the transient state of ADACOR designed by Leitao & Restivo (2006) and its real implementation. First, a Potential fields model, which takes certain constraints into account, such as dynamic transportation times and limited resource storage capacities is presented. Then, the flexibility and robustness of the approach are highlighted, with a set of scenarios performed in simulation and on a real physical system: the AIP-PRIMECA cell. These results are compared to the results provided by a mixed-integer linear model that was used to compute lower bounds. (c) 2012 Elsevier Ltd. All rights reserved.
