2016–2018 Upgrade of the optimization system for steel continuous casting
B. Filipič. Zupančič, T. TušarJ
In this applied project, a simulation-based multiobjective optimization software was developed to support continuous casting of steel on a new casting device at the Štore Steel plant. It considers the manufacturing process parameters, such as the casting temperature, casting speed and coolant flows as optimization variables, and deviations from the target values of the process output variables as optimization objectives. The output variables involved in the optimization are the solid shell thickness, the metallurgical length and the surface temperature of the cast steel. The optimization software is based on an evolutionary multiobjective optimization algorithm and interactively searches for the approximation of the Pareto-optimal front that represents trade-offs between the optimization objectives. An important software functionality is the visualization of solutions that allows the users to visually inspect and compare the solutions. The software is installed at the plant and used as a tool for achieving higher product quality.
2016–2018 Advanced methodology of evolutionary multi- and many-objective optimization for real-world applications
B. Filipič, T. Tušar, E. Dovgan, J. Zupančič
The goal of this collaboration between Japanese and Slovenian researchers was to advance the methodology of evolutionary multi- and many-objective optimization for real-world applications. It considered three important topics: (1) state-of-the-art evolutionary algorithms design and development, (2) surrogate models and visualization tools, and (3) real-world applications. Unlike most other research efforts, our research unified these approaches to effectively tackle the problems observed in complex application domains that are multi- and many-objective, computationally expensive, require surrogate models, and benefit from domain knowledge. The focus of the joint research was on optimization and visualization in many-objective space trajectory design.

2011–2014: Advanced modeling and simulation of liquid-solid process
B. Filipič, T. Tušar, M. Mlakar
The goal of this research project was to enhance the physical modeling capabilities and development of numerical methods for liquid-solid processes. Our participation in the project was focused on optimization of the alloy solidification process where the task is to determine process parameters such that the required structure of the material is obtained in the shortest possible time. Using an evolutionary multiobjective algorithm coupled with a process simulator, we minimized the concentration and structural inhomogeneities in the solidifying material and the duration of the solidification process by influencing the cooling process dynamics. Dealing with this problem was a source of motivation for our work on improving the multiobjective optimization methodology by involving surrogate models and visualizing the results, while the produced results are of practical importance for metallurgical production. The project was funded by the Slovenian Research Agency.
2010–2014: Simulation and optimization of casting, rolling and heat treatment processes for competitive production of topmost steels
B. Filipič, T. Tušar, M. Mlakar
Funded by the Slovenian Research Agency and co-funded by the Štore Steel company, this project was dealing with multiscale through-process modeling of the steel production sequence consisting of continuous casting, rolling, and heat treatment. Our role in the project was to formulate and provide a tool for solving the problem of tuning the process parameter settings for continuous casting to result in the highest possible quality of cast steel. We designed and implemented a program that accepts boundary constraints and discretization steps of the considered process parameters, and boundary constraints and target values of the selected metallurgical criteria as input. Since the criteria are conflicting, the program returns a set of trade-off solutions according to the principles of multiobjective optimization and displays them in parallel coordinates. Optimization is carried out using the DEMO (Differential Evolution for Multiobjective Optimization) algorithm, and the solutions are evaluated via an external numerical simulator of the casting process. The program is in use in the Štore Steel company.

2010–2013: EUSAS – European Urban Simulation for Asymmetric Scenarios
A. Tavčar, D. Kužnar, E. Dovgan, V. Mirchevska, B. Mahnič
The main objective of the EUSAS project is to develop methods for multi-agent modeling of asymetric conflicts. The aim is to develop a new approach to mission analysis and training for low level units facing asymmetric threats in an urban environment. Our task is to discover the common agent strategy by knowing only low-level agent behaviour and basic domain knowledge. Moreover, the objective is to transfer some of the observed behaviour patterns into highly realistic and reusable models of human behaviour in riots. The constructed models will be later used in simulations to provide a more realistic behaviour for training peace-keeping personnel.
2010–2013: MIRABEL – Micro-Request-Based Aggregation, Forecasting and Scheduling of Energy Demand, Supply and Distribution
B. Filipič, T. Tušar, E. Dovgan
Supported by the European Commission’s Seventh Framework Programme (FP7), this project was aimed at developing a conceptual and infrastructual approach that allows energy distribution companies to efficiently manage higher amounts of renewable energy and balance energy supply and demand. Specifically, we worked on a concept of micro-requests with time shifts to handle the demand and supply of energy on a household level. Further, we defined methods to predict the energy supply and demand in the small (i.e., for households) and in the large and to update predictions over time. We aggregated (and disaggregated) the micro-requests on a regional level, and we developed a scheduling approach for energy production and consumption based on aggregated requests.

2004–2006: Alvis – Superpeer Semantic Search Engine
M. Gams, V. Vidulin, M. Luštrek, A. Pivk
ALVIS was FP6 STREP project that conducted research in the design, use and interoperability of topic-specific search engines with the goal to develop an open source prototype of a distributed, semantic-based search engine. Our role in the project was to develop a prototype of genre classifier, which classifies web pages into categories such as, e.g., blog, frequently asked questions, shopping. The classifier was implemented in the search engine, where it enabled the user to search the pages not only by specifying their content (e.g., with the keyword “iPhone”), but also by specifying their genres (e.g., by specifying genre “shopping”, pages with reviews and subjective comments are excluded). In this manner, the engine returns a set of pages that are closer to user’s interests than the pages returned by the keyword-based search engines.
2004–2006: WINDECT – Wireless Local Area Network with Integration of Professional-Quality DECT Telephony
M. Špegel, P. Reinhardt, R. Blatnik
WINDECT is a novel approach to merge wireless networks by integrating professional quality telephony into WLANs to get high quality “voice over WLAN”. The result is an innovative application in the field of wireless and mobile communications. Our contribution in the project was development and construction of a research test-bed for metricsbased testing of the quality of voice communication in VoWLAN/VoIP communications. The measurements using this test-bed have provided determination of PESQ MOS, delay, jitter and packet loss derived from the analysis of analogue voice signal as well as voice packet streams. A handover tests were also performed by emulation of mobile phone’s roaming using hand attenuation of RF signals in so called »open air« from involved two access points. In the final phase of the project the test-bed was used for the performance evaluation of WINDECT-enabled mobile phones and access points in the form of demonstrator environment. The results confirm the advanages of the WINDECT approach over standard VoIP/WLAN solutions are achievable in practice. Here is the web site of the project.
