Sažetak
The aim of this work is modeling of ecological systems with special emphasis on water purification. One of asymmetric threats today is a terrorist act by which the terrorist(s) can contaminate the orgin of the drinking water. Waters are, form an ecological viewpoint, the most vulnerable to such attacks, and are also the most important part of the global ecosystem. On the Earth's aurface there are about 1, 6 x 109 km3 of water, and of these, only 0, 5 % of these waters are potable water, and the rest, 99, 5 % are seawater. Using the simulation modeling methods and techniques, we have transformed the fitted discontinuous distributions to continuous processes. This enable us to use observed discontinuous values to solve models for continuous processes. In this case, we modeled the efficiency of different absorbing materials (active carbon, zeolite A, zeolite ZSM-5, TMAZ), that can be used with different pollutants (dibutyl sulphide, different arsenic substances, different organophosphorus substances). With all collecting data it is possible to predict the behavior of these materials under different conditions such as in accidents and in situations of terrorist acts. To control the entering parameters and to get the output simulation method, we used one of the standard packages for discrete simulation, Service model v4.2 (ProModel Corporation) and for continuous control of the processes we used Extend v4 (Imagine That, Inc.).
