Zyma A. Modelling enterprise's competitiveness in unstable economic environment

Object of research: processes, related to forming and dynamics of competitiveness of industrial enterprise, functioning in the conditions of unstable economic environment. Purpose of research: economical and mathematical modeling of competitiveness of industrial enterprise in the conditions of unstable economic environment for the increase of efficiency of his functioning. Methods of research: method of analysis and synthesis; approach of the systems and theory of the viable systems; methods of making decision; optimization modeling; imitation modeling and system dynamics; modern technologies of planning of the informational and analytical systems. Results: authorial determination of economic categories is offered: "competitiveness of industrial enterprise" and "unstable economic environment"; complex methodology of estimation of synthetic index of competitiveness of industrial enterprise and feature of her application is generalized for an enterprise; conception of modeling of competitiveness of industrial enterprise is worked out in the conditions of unstable economic environment; the structural model of process of increase of competitiveness of industrial enterprise is worked out in the conditions of unstable economic environment; the multicriterion model of optimization of competitiveness of industrial enterprise is worked out in the conditions of unstable economic environment; the simulation model of competitiveness of industrial enterprise is built in the conditions of unstable economic environment; the structure of the system of support of making decision of industrial enterprise is worked out for the increase of efficiency and competitiveness in the conditions of unstable economic environment; the simulation model of competitiveness of industrial enterprise is realized in the conditions of unstable economic environment in PowerSim; authenticity, fitness and efficiency of models, is well-proven for prognostication of the state of enterprise and estimation of dynamics of his competitiveness in the conditions of unstable economic environment. Novelty: first: conception of modeling of competitiveness of industrial enterprise is worked out in the conditions of unstable economic environment; the multicriterion model of optimization of competitiveness of industrial enterprise is worked out in the conditions of unstable economic environment; improved: simulation model of competitiveness of industrial enterprise in the conditions of unstable economic environment; structure of the system of support of making decision of industrial enterprise; got further development: structural model of process of increase of competitiveness of industrial enterprise. Field of the use: level of enterprises.
