Simulation of the capital structure of an enterprise taking into account the dynamics of parameters of the external environment

Information technology is an effective tool for substantiating management decisions in any field of activity, including the economy. One of the most important characteristics of the functioning of economic agents in a market is the structure of their capital because the interest of foreign investors in the business entity depends directly on the balance of this structure. Therefore, the process of managing the capital structure of a business unit needs special attention both in terms of sustainable development and during the crisis. Given the mentioned above, the object of the study is the process of managing the enterprise capital structure. The study aims to improve the methodological support of the process of managing the enterprise capital structure taking into account the dynamics of the parameters of the external environment of its operation. As for the results of the research, the EPC diagram of the optimization process of the enterprise capital structure was developed. Due to the use of the vector graphic editor MS Visio, this model allows visually displaying the scenario of a financial manager’s activity during performance of his duties on the modeled subject area; the methodical approach to assessing the sustainability of capital structure management based on the building of Shewhart quality maps was suggested. Such maps enable to identify typical (optimal, preventive and control) values of the components of the capital structure of an entrepreneurial unit; methodical recommendations for operative management on an enterprise capital structure at the innovation and investment stage of its development were developed. They are based on the use of a method of linear programming. They allow defining possible deviations of capital structure indicators while retaining the control of the chosen strategy of its development.
