The analysis and control of dynamic material flows in traffic, production, and logistics is a subject of contemporary interest. In this contribution, we introduce a generalised input-output model of commodity flows that allows to study the dynamics of production and supply networks under different production strategies. It is demonstrated that production units subjected to a temporally varying demand and/or supply show an amplification of these variations for both push and pull strategies. Using an extended linear stability analysis, we identify under which conditions a consideration of mixed push-pull strategies leads to a suppression of these effects. Our corresponding results have important implications for the strategic planning and control of manufacturing networks.
