Cellular Automata Modelling of Large Scale Systems and VLSI Implementation Perspectives

摘要

Modelling of Large Scale Systems is an interesting research area since it combines issues of risk management and human decision. Strongly related with social, environmental and economic consequences, such issues impel scientific community to investigate for efficient and applicable solutions. To this direction, phenomena involving mass human presence, as crowd panic or extended natural processes, as earthquakes, have been simulated, using a computational intelligent technique, based on Cellular Automata (CA). CA are very effective in simulating physical systems, capturing the essential features of systems where global behaviour arises from the collective effect of simple components which interact locally. Moreover, they are also one of the most suitable computational structures for VLSI realization. The evaluation of each model is based on its response to real data. In both cases, an efficient graphical user interface has been developed, in order to study various hypotheses concerning the prominent features of each model.
