COMPARISON OF DIFFERENT MODELS OF THE MOVEMENT OF HUMAN FLOWS AND RESULTS OF PROGRAM COMPUTER SYSTEMS
With consider regulation process of evacuation of people in emergency situations program computer systems which have to give the chance to analyse different settlement situations at the solution of problems of ensuring fire safety in buildings of different classes of functional fire danger are developed now. Compliance of results of the calculations perfromed by these program computer systems, to data of natural supervision of the movement of human flows in actual practice has to be an indispensable condition of possibility of their application in rationing. Therefore paramount criterion of applicability of any of such program complexes is the validity of model of evacuation which they use. It is shown that simplified the analytical and imitating and stochastic models based on extensive statistical material of researches of human streams in buildings of various functional purpose with their various structure of the main contingent of people and on the determined consistent patterns of communication between parameters of flows ofpeople of any psychophysiological state are correctly described by program computer systems ADLPV-2.0, "Floutek VD". These models reflect also the kinematic dependences of change of parameters of a flow occurring upon its transition through the borders of adjacent sites of an evacuation way described by a graphic-analytical method. The comparative analysis with these results of results of the individual and line model given in "A technique of determination of settlement sizes of fire risk in buildings, constructions and structures of various classes of functional fire danger" demonstrates a dissonance of this model. The analysis of results of the program of the individual flow movement "Evatek" model shows their convergence with the results close to the lower bound of a confidential interval of an estimated time of evacuation. The model demands completion of reproduction of kinematics of individual behavior of people. The analysis of foreign models of the individual flow movement of people which is carried out on the example of the program "PathFinder" and "FDS+Evac" complexes shows that they use dependences between parameters of streams not corresponding to human streams. As a result of the carried-out analysis comes to light that for modeling of process of evacuation it is necessary to use imitating and stochastic model of the movement of human flows which most precisely reflects dynamics of process in different exploitation conditions of the building.
