SYSTEM - DYNAMIC MODELLING IN MODERN RUSSIA

摘要

The significant results within the framework of system dynamics are achieved now in manycountries. In Russia, for example, the tools of system dynamics is successfully applied to economic,social and ecological problems in some universities of economic orientation, including theEconomic Faculty of M.V. Lomonosov Moscow State University, S. Ordzhonikidze StateUniversity of Management (Moscow), G.V. Plekhanov Russian Academy of Economics (Moscow),Academy of National Economy under the Russian Government (Moscow), Moscow StateUniversity of Economics, Statistics and Informatics, Far East State University, Baikal Institute ofEnvironmental Management of the Siberian Branch of the Russian Academy of Sciences etc.Besides the system dynamic tools are applied as important part of constituting situational centers insome Russian companies.Alongside with the known international means of the visual modeling which were widespreadin 90th. of XX centuries, such as Vensim (Ventana Systems, USA); Powersim (Powersim AS,Norway); Process Charter (Scitor, USA); Ithink (Stella) (High Performance Systems, USA); ExtendBPR (Imagine That!, USA); ReThink (Gensym, USA), Simulink (Math Works, USA) etc., thefollowing domestic means of visual modeling also were widespread in Russia: IMITAK (SUM,Moscow), FEYA (RAE, Moscow); PODSIM, RDO (Bauman Moscow State Technical University),DSIM (ENIMS, Moscow), PETRIS (Penza State University), STRATUM (Stratum ModelingGroup, Perm); Pilgrim-2.1 (Megathrone, Russia; Keisy, Netherlands; EnitAS, Estonia) etc. Besidesthe following CASE-tools have widespread enough in Russia: BPWin and ERWin (PlatinumTechnology/Logic Works, USA), Designer/2000 (Oracle, USA); ARIS (IDS AG, Germany); SAPR/3 (SAP AG, Germany), Case Analitic (MacroProject, Moscow) etc.Nevertheless, in many "classical" languages of visual system dynamic modeling now there areno the means, allowing to analyze spatially distributed data, and also to investigate the optimumcontrol models (for example, Ramsey and others macroeconomic models of endogenous growth),for which it is important to find the program control trajectory and the appropriate trajectories forthe variables describing state of the system. In technical languages of simulating modeling theselimitations are overcome by programming necessary tools of the data and models analysis by meansof high level programming languages, however, this way is not accessible to many humanitarianexperts (such as economists, sociologists etc.). Therefore the decision of such problems with use ofvisual means of system dynamic modeling is more perspective. So the Moscow State Universitygroup of scientists under supervision of Vladimir Sidorenko created in 2000-2001 the educationalversion of software, which allows to design and analyze the system dynamic models with spatialdynamics and also to solve a set of problems connected with the optimum control theory (search ofprogram control etc.) and games theory (search of game balance etc.). Some of the ideas wereimplemented into the GIS and system dynamics simulator "ECONET", which was presented inISAGA-2000 Conference. The software is successfully used now within the following courses:"System dynamics", "Mathematical models in environmental economy", "Application of nonlineardynamics tools and intellectual information technologies in economy".
