The article covers issues of effectiveness of working capital management of a trading enterprise on the basis of the automated planning. This approach gives the possibility to use the classical methods of optimization of dynamic systems to determine the main parameters of the economic policy of the commercial enterprise for providing the best strategy for development. With using the proposed approach can be created algorithms for evaluating both managed and unmanaged risk and also for finding reasonable solutions for preventing them. When presenting the material, operational environment of the commercial enterprise is describing in traditional terms of trade and financial market, allowing its use wherever used information system "1C", in the form of incremental software complex for forecastingand optimization. The developed mathematical model allows to solve the tasks of easing the selection and justification decisions for leadership shopping enterprise: - predict a time functions, which define the mathematical expectations of the processes of change of assets and liabilities of commercial enterprise in the process of its functioning, as well as confidence intervals; - with initial set of source data - find the initial condition - authorized capital for providing strategic objectives; - with any statutory Fund - to identify primary commodity-monetary policy, expressed by set of different interest rates, some of which is set by the regulator, the other part -by market mechanisms and Treaty obligations of participants of transactions, that will allow to solve tasks at the initial period of functioning; - provide support to the enterprise operation planning in the form of calculation of efficiency of variants of produced plans and other. Results of forecasting the dynamics of the situation circulating assets are presented inan integrated graphical form, which provides an opportunity to see the full picture of the forthcoming state of current assets trade organization, and the main participants of the trade and economic activity in a given time interval.

We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.
We consider the spaces of functions on the m-dimensional torus, whose Fourier transform is p -summable. We obtain estimates for the norms of the exponential functions deformed by a C1 -smooth phase. The results generalize to the multidimensional case the one-dimensional results obtained by the author earlier in “Quantitative estimates in the Beurling—Helson theorem”, Sbornik: Mathematics, 201:12 (2010), 1811 – 1836.
