The goal of SW modules, with which it is possible to obtain information about stationary and mobile activities in public space from the camera system. This will make it possible to automate the current method of observation and allow the expert a faster and more accurate assessment of the quality of the analyzed space (how, for example, the proposed space is used by the public and whether the stated intention has been achieved).
This report summarizes outcomes and achievements of project LEGO Adaptive Finalpack. The main goal of this project was to analyze the current LEGO production. The process is composed of the steps as follows: (1) definition of production recipe for a new product, (2) identification of time and cost parameters for individual production steps, (3) Long-term production planning, Short-term production scheduling, and (4) production. The main focus was on the identification of challenges that modular production lines can inject into the whole value chain. The final output of this activity was an innovation strategy for the next five years to transform the current fixed production line setup into an adaptive production environment.
This report summarizes the outcomes and achievements of project LEGO Digital Prepack. The main goal of this project was to analyze the behavior of LEGO packing lines that produce Prapacks, i.e., plastic bags filled with LEGO bricks. The pre-pack lines are composed of three key types of components: Counting Machines, Scales, and case packs. The main attention was paid to the development od optimization method to improve the behavior of these components in terms of speed, reliability, and production quality.
Facility layout problems, i.e., optimal placement of production units in a plant, become an inseparable part of manufacturing systems design and management. 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.

This research aims to provide architects with an interactive Finite Element (FE) analysis during the conceptual design phase through the development of a "middle-ware", a bridging tool between an FE solver and the architectural modelling environment. Architects are typically not trained to use expert FE analysis software directly. Therefore, simplified FE modelling, as well as concise presentation and interpretation of analysis results would be beneficial in early stages of the design process. Simplified result interpretation should help architects to identify structural problems and guide them towards structurally improved designs. This will allow them to not just independently evaluate a theoretically unlimited number of design alternatives, but also to find better structural solutions. To develop a means of simplified structural evaluation, a review was carried out of existing form finding, evolutionary structural optimization and other optimization methods and tools. The resulting Structural Evaluation Assistant (SEA) method, which uses the Von Mises criterion, informs architects about different levels of structural efficiency and feasibility. This paper shows how the SEA supports FE analysis result interpretation and the architect’s decision making during design process. It does so by generating a score for the whole structure, and visualizing all structural design alternatives in order to compare them during the design process. Compared to other FE-based tools, a strong emphasis is placed on the visualization and interpretation of the results. The developed evaluation assistant supports the architects' decision making and improves their structural intuition during the design process.
This paper presents a methodology and software tools for parametric design of complex architectural objects, called digital or algorithmic forms. In order to provide a flexible tool, the proposed design philosophy involves two open source utilities DONKEY and MIDAS written in Grasshopper algorithm editor and C++, respectively, that are to be linked with a scripting-based architectural modellers Rhinoceros, IntelliCAD and the open source Finite Element solver OOFEM. The emphasis is put on the structural response in order to provide architects with a consistent learning framework and an insight into structural behaviour of designed objects. As demonstrated on three case studies, the proposed modular solution is capable of handling objects of considerable structural complexity, thereby accelerating the process of finding procedural design parameters from orders of weeks to days or hours.
EmCity is a simulation decision-making and analytical software tool for architetcs and urban planners. The tool is based on nonlinear and unpredictable agent-based simulation of urban growth and reconfiguration of the urban pattern that utilizes several computational algorithms in terms of Swarming behavoir, Stigmergy, Attraction and Path following. The tool provides observation and exploration of potentials of urban development and simulation of equable grainines of urban activities in South City in Prague based on approach distance as an essential bottom-up strategy of urban development. Thus the simulation model allows user to simulate the emergent behavior of the urban pattern utilising several parameters of leading of agent flows. There are several possibilities of exporting the model into graphical outputs for further obsevation, evaluation and consideration.

The main purpose of this research is to introduce and verify selected advanced
computational methodologies operating with agent-oriented approach that are
applicable within the framework of emergent urban design strategies in early
stages of zoning proceedings. The aim is to demonstrate that speculative matter
of the phenomenon of emergence in terms of design thought driven by
computational models can also be applicable within real existing urban
conditions. The research concurs previous researches in the field of urban
pre-reconfigurations in the selected city environments. It concentrates on
developing a simulation model as an analytical and generative instrumental
platform for architects in early phases of urban design and synthetizes
accumulated computational advancements based on agent-oriented approach.

This paper deals with possibilities for evaluation and visualization of structural
solutions created in the conceptual design phase. The goal is to support
transparency of structural analysis results, and to support architects'
decision-making by providing them with opportunity to compare different
structural solutions. Research will be implemented into the developed software
tool, with the aim to support architects in the shaping process and to teach them
to better understand form and forces.
In this paper we describe the pedagogical and methodological approach to a parametric project and workshop for the design of a tower which consists of 150000 PET bottles. The ultimate goal of the project is to actually realize the PET bottle tower; therefore the constraints on the projects are very strict. Additionally, because of the large number of bottles to be used in the design, the problem lends itself well to a parametric approach.
