Production and supply networks are complex networks of nonlinear dynamical elements designed to fulfill certain functional requirements. By using recently developed models we study the interaction and dynamics of production units exchanging material and information in such network structures. Whereas the directed flow of materials introduces a coupling between nearest neighbours in a supply network, the accompanying information network can involve even long range interactions. The stability and robustness under demand variations with respect to the topology of the underlying network structures is investigated. Surprisingly, even small changes in network topology can lead to different dynamics. Furthermore, for a fixed material flow network, the stability and dynamical behaviour of the system can be influenced significantly by changing the structure of the sub-network for information exchange. These results can be used to optimize the structure of the material flow network and the information network in order to obtain more reliable, stable and robust supply networks.
