Christian Reintjes presents his research at the International Conference on Operations Research and his research paper is accepted for publication in the conference proceedings.

On 7 September, Christian Reintjes, scholar of the SME Graduate School, presented his research results on the topic „Lattice Structure Design with Linear Optimization for Additive Manufacturing as an Initial Design in the Field of Generative Design“ as part of the International Conference on Operations Research in Berlin. Furthermore his research paper (together with his co-authors Michael Hartisch and Ulf Lorenz) was accepted for publication by the Operations Reserach Proceedings 2017, Selected Papers of the International Conference on Operations Research.

 

            

 

More than 800 practitioners and academics from mathematics, computer science, economics, engineering, and related fields participated at the International Conference on Operations Research at the Campus of Freie Universität Berlin.

The conference motto “Decision Analytics for the Digital Economy” takes up the trends that are currently empowering the field more than ever before, opening up new areas of applications in industry and society, and giving rise to exciting scientific challenges.

The research paper „Lattice Structure Design with Linear Optimization for Additive Manufacturing as an Initial Design in the Field of Generative Design“ and the related conference presentation provides a mixed-integer linear program to describe the static load distribution in a two-dimensional space as a first starting point to create construction proposals, with the technical background knowledge that the combination of optimization tools of any kind and additive manufacturing should be able to improve lightweight construction. Over the last decade technical optimization became increasingly important for the modern, energy-efficient and therefore material-saving construction.

The traditional approach uses construction software combined with human knowledge to produce CAD-drawings and to display all technical data. The results can be considered in succeeding analysis, e.g. numerical or nonlinear toplogy optimization. Irrespective of the quality of those methods, the initial drawing still is a product of the human intellectual capacity.

 

Our approach is to use optimization in the first instance to generate the design itself. Therefore, we want to provide optimization tools to compute the design, since it might be possible that the computer-based design outperforms the human-based design.
