Multi-Goal Control in Supply and Production Networks — •Stefan Lämmer — University of Technology Dresden, A.-Schubert-Str. 23, 01062 Dresden, Germany

Supply networks consist of many manufacturing and distribution organizations, interconnected by the flow of information, money and goods. Each organization has a number of functions, specializing in the flow of typically more than one kind of product. A low inventory of one product may call for an increase in the production rate, but the warehouse for another product, which is generated at the same time, may be already full. Recent supply network models indicate that the network of material flow can itself be a source of instability, and oscillatory variations are an inherent feature of decentralized adjustment processes. We conjecture that multi-goal control of production networks may imply additional sources of dynamical instabilities and that some of the problems may be solved by price adjustments, which can influence the consumption rates.
