Suitable algorithms and architectures for the application of multi agent systems within a shop iloor control system arc developed in this paper. In particular, the algorithm discussed here is focussed on the achievement of high and consistent levels or production throughput in a manufacturing flow shop environment where there is a significant degree or flexibility associated with route selection. It is intended that in addition to performing well under nominal operating conditions, that such algorithms support a control system that is robust in the face of typical but unexpected process disturbances, such as congestion. It is emphasised that the algorithms are primarily intended for shop floor control and execution rather than scheduling for which numerous existing algorithms already exist. The paper presents a particular back pressure algorithm for routing selection and combines with this a simple agent environment for determining feasible routes.
