Results in Hungarian
Új algoritmuscsaládot fejlesztettünk ki, a bakteriális memetikus algoritmusokat, a bakteriális evolúciós algoritmust globális, a Levenberg-Marquard algoritmust pedig lokális keresésként alkalmazva. Ez az eljárás jobb algoritmusokat eredményezett az ismert hasonló módszereknél a pontosság és a ciklusszám összefüggésében; ezt különböző referencia alkalmazások és más példák segítségével bizonyítottuk. Az alkalmazások másik csoportját a logisztika adta. Kiterjesztettük Kano minőségi modelljét fuzzy exponensekre, melyet BMA-val optimalizáltunk és megkezdtük az utazó ügynök probléma közelítő megoldásának vizsgálatát is. Megmutattuk, hogy a fuzzy szabályinterpoláció számos valós probléma megoldására alkalmas. Sikeresen foglalkoztunk komplex forgalomirányítási alkalmazásokkal, továbbá vasúti menetrend és késés miatti átütemezés kérdéskörével. Szoftverrendszert implementáltunk, mely nagyszámú fuzzy következtetési és irányítási algoritmus összehasonlítására alkalmas. Kiterjesztettük a fuzzy szignatúrákat hierarchikus struktúrákra is és a Mamdani algoritmusra is. A fuzzy szignatúrákat robotok mozgásirányítására és kommunikációjára alkalmaztuk. E robotokat szimulációs technikával és saját fejlesztésű hardver segítségével is vizsgáltuk. Új kutatási részterületet indítottunk el a fuzzy műveletek és a rajtuk alapuló fuzzy flip-floppok vizsgálatával, melyekből konnekcionista rendszereket hoztunk létre és e fuzzy neurális hálózatokat modellkonstrukcióra és approximációra alkalmaztuk.
Results in English
We developed a new family of algorithms, the Bacterial Memetic Algorithms by combining the Bacterial Evolutionary Algorithm as a global search and the Levenberg-Marquard algorithm as a local search method. This approach provided better algorithms in terms of approximation accuracy and population cycles than other similar approaches in the literature, as it was evidenced by various benchmark and real life applications. Another group of successful applications is in the logistics area. We extended Kano’s quality model to fuzzy exponents, optimized by BMA, and we started to research for the approximate solution of the Traveling Salesman Problem.We showed that fuzzy rule interpolation could be deployed for a number of real application areas. We dealt with complex traffic control applications as well as with railway time table and delay triggered rescheduling problems successfully. We implemented a software for the comparison of a large number of fuzzy reasoning and control algorithms. We extended Fuzzy Signatures to both hierarchical structures and Mamdani’s algorithm. We applied Fuzzy Signatures for motion control and fuzzy communication of robots. Such robots were investigated both in simulation and hardware construction developed by ourselves. We started a new research sub-direction by analyzing fuzzy operators and fuzzy flip-flops based on them. We built connectionist systems from them and we used these fuzzy neural networks for model construction and approximation.
