The methodology of computer simulation of nonstationary fields of temperatures, concentration and pressure is considered. The computer model of non-stationary heat exchanging process is researched. Decentralization interaction of the active parallel agents is the base for computer implementation. Agents are defined as abstraction of elements of physical system where the modeled processes proceed. Process characteristics are calculated on the base of information on non-stationary fields of temperatures of a wall of...

Nowadays, efficient urban transportation systems have a very strong impact on economic prosperity and development. The quantity and quality of transport infrastructure can influence attractiveness and desirability of urban regions for certain industries and can affect the quality of life of its citizen. Passenger transportation systems are characterized by complexity of its behavior and a high level of uncertainty; therefore simulation technologies have become an effective tool for their modeling and managerial de...

Lots of modern heat supply systems were designed and constructed many years ago, but used today with low efficiency. The task of optimization of heat supply systems to increase the efficiency of such systems is related with high capital expenses of such process, but also with high mutual integration of heat supply systems with other infrastructure objects. In this regard the heat supply organizations are faced with a task of optimization of the efficiency indicators of functioning heat supply systems with minimal ...
