Shibko O. Management by the Transformations Program at the Enterprise on the Results of its Life Cycle Designing

Object of research - the process of release GDP, which supports the sustainable operation of enterprises. The aim of the thesis is to develop methods and mathematical software for the creation of a special project company with the economic parameters, which ensure its stable operation and ruhlyvist.Metody research: methods of systems theory and systems analysis; methods of optimal control theory; methods of probability theory and mathematical statistics; modeling techniques. The proposed method of simulation of crisis within the company and developed mathematical software can be used in enterprises that produce uniform product. Methods of modeling the dynamics of construction firms, structural and circuit simulation program for the PDS modeling language system implemented in the educational process of the university "Dnieper State Academy of Civil Engineering and Architecture." Modeling techniques of crisis within the company, its behavior in market conditions and the corresponding software module decision support systems adopted in the trial operation of "Interbud." The novelty of the results: the first time created a mathematical model of life cycle based on a continuous dynamic process that allows to predict the behavior of enterprises in the future, to plan its development, determine the time out on a given need, analyze the stability of the enterprise, to simulate crisis situations within the company and its behavior in market conditions; first performed analytical design and construction process of release GDP, obtained analytical dependence, linking outflow rates and growth (update) of fixed assets with weights, quadratic functional as a set of optimal coefficients disposal area and the growth of basic production funds and proved that these coefficients can be variable life-cycle enterprise composed mathematical model probabilities of states of the life cycle and enterprise-based modeling proved the possibility of increasing the duration of stage of maturity due to the periodic transfer of the enterprise with the stage of maturity to the stage of development by updating products and technologies or developing a new investment project to model the life cycle of enterprise modeling performed crisis within the company and its conduct of the company's market, the results of which can develop principles and guidelines of crisis management strategies. Range of application: companies that produce uniform product.
