They are known to greatly impact the system performance. This paper proposes a new formulation of the facility layout problem where workstations are to be placed into a hall. Within the hall, obstacles and communications can be defined. Each workstation can have multiple handling spaces attached to its sides and oriented links can be defined between workstations. A new evolutionary-based approach to solve this facility layout problem is proposed in single-objective as well as multi-objective variant. The method is experimentally evaluated on a set of standard VLSI floorplanning benchmarks as well as on the data set created specifically for the proposed facility layout problem. Results show the method is both competitive to the state-of-the-art floorplanners on the VLSI benchmarks and produces high-quality solutions to the proposed facility layout problem.

The co-design among community and tran-sdisciplinary participants with different expertise required scope of media mix, switching between analogue, digital and back again. This involves different degrees of physical and digital ‘GIGA-Mapping’ (Sevaldson, 2011, 2015), ‘Grasshopper3d’ (Davidson, 2017) scripting and mix of digital and analogue fabrication to address the real life world. The critical participation of this ‘Time-Based Design’ (Sevaldson, 2004, 2005) process is the interaction of the prototype with eco-systemic agency of the adjacent environment – the eco-systemic performance. The TreeHugger is a responsive solid wood insect hotel, generating habitats and edible landscaping (Creasy, 2004) on bio-tope in city centre of Prague. To extend the impact, the code was uploaded for communities to download, local-specifically edit and apply worldwide. Thus, the fusion of discussed proc...

Its panelling is warping in the sun and low relative humidity, thus supporting the circulation of humid air in its environment. Loop is a contribution to the Research by Design on Responsive Wood started by Michael Hensel and Achim Menges at the AA School of Architecture in 2005 and is a second prototype of the first author’s Environmental Summer Pavilions project that developed the previous one, pareSITE Pavilion, further. By spatial organisation of its panelling and the shape of the overall structure, we reached much higher performance. The design was accomplished in Grasshopper for Rhino 5 and digitally fabricated. The project is a result of a transdisciplinary, one semester lasting, studio course at the Faculty of Art and Architecture at the Technical University of Liberec and the Faculty of Forestry and Wood Sciences at the Czech University of Life Sciences in Prague le...

Recycled filament can be bought in Argentina or Netherlands but lack of experience with this reborn material blocks its use in the Czech Republic. Firstly we made a study of settings of the home-3D-printers for this material. Secondly we came with a crowd printing project, which tested the possibility to print structural pieces by on various low-cost printers.
