A mathematical model to make strategic decisions on the design of the supply chain of products with high added value of the associated petroleum gas sold in the mathematical programming language AMPL. The model allows to determine the optimal location of production and logistics facilities, mode of transportation and storage, as well as to decide on the building of capacities, choice of market implementation of the final product.
The paper presents a framework for numerical simulation that allows you to ensure saving of resources due to the numerical selection of the optimal size and temperatures in the preparation of bimetallic castings. Modeling obtained boundary and initial conditions at which the metal parts submelting first layer in the contact area with the second layer and is saved in the unmelted state of the first layer with a thickness of 1.5-2 mm, which is in contact with the mold.
The negative impact of logistics and especially transport andits infrastructure on the environment is quite extensive and includescurrent international problem of greenhouse gas emissions into theatmosphere and corresponding climate change. According to sta-tistics 28% of emissions accounted for by transportation. Devel-opment and implementation of appropriate initiatives of reducingthe negative environmental impact of transportation takes place ondifferent levels. This is the result of the Kyoto Protocol, and now ofthe Paris agreement. Internationally, the system of both normative-legal and economic methods of state and market regulation is ac-tively applied and improved in order to stimulate the introductionof “green” technologies. The article analyzes the advantages anddisadvantages of the existing Russian and foreign methods andeconomic incentives for solving an environmental problems thatcaused by the development of transportation and logistics infra-structure. Article explores the tax policy of foreign countries in thefield of ecology; types and amounts of charges of basic environ-mental taxes. The “shadow prices” method is considered as a pos-sible methodological basis for calculating and subsequently intro-ducing an environmental tax for a specific pollutant. The articleproposes changes in the economic policy of the development of“green” logistics in Russia based on an analysis of the results of fi-nancial and tax instruments application in different countries. In par-ticular, it is shown that Russia can effectively use the experience ofGermany and other countries on the transport tax differentiation(depending on emissions and other environmental indicators), aswell as possible ways of improving current charges pollution and
emissions charges.
In this paper we consider choice problems under the assumption that the preferences of the decision maker are expressed in the form of a parametric partial weak order without assuming the existence of any value function. We investigate both the sensitivity (stability) of each non-dominated solution with respect to the changes of parameters of this order, and the sensitivity of the set of non-dominated solutions as a whole to similar changes. We show that this type of sensitivity analysis can be performed by employing techniques of linear programming.
The paper examines the structure, governance, and balance sheets of state-controlled banks in Russia, which accounted for over 55 percent of the total assets in the country's banking system in early 2012. The author offers a credible estimate of the size of the country's state banking sector by including banks that are indirectly owned by public organizations. Contrary to some predictions based on the theoretical literature on economic transition, he explains the relatively high profitability and efficiency of Russian state-controlled banks by pointing to their competitive position in such functions as acquisition and disposal of assets on behalf of the government. Also suggested in the paper is a different way of looking at market concentration in Russia (by consolidating the market shares of core state-controlled banks), which produces a picture of a more concentrated market than officially reported. Lastly, one of the author's interesting conclusions is that China provides a better benchmark than the formerly centrally planned economies of Central and Eastern Europe by which to assess the viability of state ownership of banks in Russia and to evaluate the country's banking sector.

One of the most important indicators of company's success is the increase of its value. The article investigates traditional methods of company's value assessment and the evidence that the application of these methods is incorrect in the new stage of economy. So it is necessary to create a new method of valuation based on the new main sources of company's success that is its intellectual capital.
