    Combination of Optimization Methods and Material Flow Analysis for Improvement of Operational Material Use (KOMSA): Concept and its Implementation
    (Environmental Informatics and Industrial Ecology, 2008) Lambrecht, Hendrik; Zimmermann, Mike
    The research project KOMSA makes a contribution to an efficient use of materials and energy in industrial production. An innovative combination of methods from material flow analysis, as realized by the software tool Umberto®, and optimization strategies commonly used in operations research closes an important methodological and instrumental gap. Our aim is to develop a material flow based optimization tool that enables users with just basic knowledge of operations research and optimization theory to nonetheless profit from well established optimization algorithms. Beyond their classical function to map one-to-one relationships within material flow systems, the flexibility of material flow networks shall be exploited in order to support users in their task of defining and structuring material flow based decision problems.

    Optimisation Approaches in Material Flow Models of Manufacturing Systems
    (Environmental Informatics and Systems Research, 2007) Schmidt, Mario; Lambrecht, Hendrik; Möller, Andreas
    For many years now highly developed models and software tools have been applied in ecological material flow analysis. They offer many possibilities for complex modelling of material flow systems, but do not take into account the approaches of Operations Research for optimising such systems with regard to objective functions to be selected to and within the context of existing constraints. A current research project combines the method of material flow nets, implemented in the software Umberto®, with corresponding optimising algorithms. The result offers a new look at real material flow systems and how they can be economically and ecologically improved.
