Ponomarenko O. Modeling of the flexible management system of the investment activity of a large industrial complex

Research object: the investment activity of large industrial complexes (LIC). Research purpose: the development of theoretical fundamentals and models of synthesis of the flexible management system of the investment activity of a large industrial complex, aimed at the increase of efficiency of its functioning, which provides fulfilment of its mission, marketing competition and financial stability. Methods of research: systems analysis, methods of economic and mathematical modelling, mathematical statistics, operation research, financial analysis and system dynamics. Results: the distinctive features of LIC's investment activity are detected; the conceptual and technological fundamentals of organization of the flexible management system of LIC's investment activity are developed at the theoretical level; the integrated non-linear model of the flexible production and investment strategy of LIC is synthesized, the analysis of its sensitivity and solution methods is conducted; the multi-criteria compromis e models system of portfolio forming is formulated; the investment decisions support system is offered; the simulation model of efficiency estimation of the flexible management system of LIC's investment activity is constructed on the basis of the system dynamics method. Novelty: the concept of the flexible management system of the LIC's investment activity under unstable conditions of functioning grounded on a continuous analysis of destabilizing factors of external and internal conditions of functioning, which promotes efficient portfolio management adequately to the degree of deviations by minimizing costs of composition and updating of LIC' investment strategy and portfolio for given time with the help of external and internal investment strategy realization synchronization in time; according to the given concept the counterpart technology of organization is worked out; the integrated model of the flexible LIC's production and investment strategy, supporting a tactical flexibility of LIC's investment mana gement, which maximizes probability of achieving the satisfactory level of return on equity subject to maintenance of the solvency; the system of multi-criteria models of portfolio forming of LIC as risk aversion investor synthesized with the help of compromise programming, which allows to select an optimal portfolio on interception of efficient and compromise sets; the simulation model of an efficiency estimation of the flexible management system of LIC' investment activity, grounded on a system dynamics method, which enables to observe the realization of the synthesized strategy under the influence of the destabilizing factors of an investment climate and internal conditions of operation. Field of use: large industrial enterprises.
