Integrated production networks can be very efficient in using raw materials and energies resulting in optimized cost structures. In particular in the chemical industry integrated production networks gain competitive advantage. However, the complexity of large networks makes it difficult to predict and navigate through volatile markets and to define development strategies to meet future market demands. But, by using extended material flow analysis effects of changes in production networks can be predicted. Starting with material flow analysis and extending with cost and investment analyses while using scenario techniques, an optimized configuration of the network can be identified. Therefore, extended material flow analysis supports the strategic development of the integrated production network.
