Деловой климат в оптовой торговле в III квартале 2014 года
The article gives a brief description of the current state of the wholesale trade in terms of the dynamics of the main statistical indicators in this field of economy as well as on the background of the historical development. Defining the place and role of wholesalers in the supply chain, factors threatening to their competitiveness and existence are identified. To counter the challenges, the focus on providing logistics services on the basis of the adopted customer service policy is proposed as a solution. Making customer service policy it is recommended to start with the coordination of the strategies of different levels and different functional areas of the company.
Procedures of minimization of the total costs/penalties caused by service of orders in links of chains of deliveries are presented. They are discussed and formalized for the first time with reference to models when it is necessary to consider variable tariffs of such penalties at their decrease in time under the scheme of continuous percent.
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.
