Оптимизация запасов дистрибьюторской компании по многим критериям с учетом рисков
Solution optimization procedures with the following features are first proposed for a supply chain for the inventory management models in distribution companies 1) Taking into account risks using the method of the decision tree. 2) Making multi-criteria decision. 3) The synthesis of procedures indicated decision with the analytic hierarchy processes. The proposed approach to the choice of decisions will allow managers to get rid of the "blindness" phenomenon with differently directed criteria, as well as the phenomenon of inadequate choice. In addition, it will allow to take into account the decision maker preferences, as well as the risk factors that increase the quality of decisions. Illustrations of the approach are given on the example of a distribution company that mainly sells confectionery and grocery products.
Nowadays, most of the people are suffering from the attack of chronic diseases because of their lifestyle, food habits, and reduction in physical activities. Diabetes is one of the most common chronic diseases being suffered by the people of all ages. As a result, the healthcare sector is generating extensive data containing huge volume, enormous velocity, and a vast variety of heterogeneous sources. In such scenario, scientific solutions offer to harness these massive, heterogeneous and complex datasets to obtain more meaningful information. Moreover, machine learning algorithms can play a tremendous part in creating a statistical prediction-based model. The aim of this paper is to identify the prevalence of diabetes related to long-term complications among patients with type-2 diabetes mellitus. The processing and statistical analysis require machine learning environment known as Scikit-Learn, Pandas for Python, and R-Studio for R. In this work, machine learning approaches such as decision tree, random forest for developing classification system-based prediction model to assess type-2 diabetes mellitus chronic diseases have been studied. Additionally, we have proposed an algorithm which is solely based on random forest and tried to detect the complicated areas of type-2 diabetes patients.
The problem of management is formalized for the first time by purchases as a problem of a choice of the best decision at many criteria. Thus some of private criteria allow to consider demanded risk factors. Possibilities of the decision of problems of this kind on the basis of a method of a tree of decisions are illustrated.
Current processes of globalization and integration of the companies into the world economy necessitated the unification of financial reporting to the third parties and external users, its transparency and uniformity of financial calculations and calculation procedures. International Financial Reporting Standards (IFRS) today play the role of a certain standard or an example of how international companies have to generate financial reports. This imposes certain obligations on the reporting procedure. Thus, on the one hand companies operate under strict rules of how and that they can be reported. On the other hand, oil and gas companies implement large risky projects, which feasibility evaluation is often difficult in the conditions of high risk and lack of the information. This situation is typical for offshore fields, particularly in the Arctic offshore, where the degree of exploration is extremely low. The present article is concerned with the real options valuation of offshore fields in the Arctic. The main point of the article is an example of the subsequent correlation of the price value of the real options and possible costs for exploration and evaluation of the field resource potential in accordance with the principles of IFRS 6 – «Exploration for and Evaluation of Mineral Resources», an accounting standard that is core to the understanding of accounting in the mining and oil and gas industries. IFRS 6 includes modified impairment testing of exploration and evaluation assets and replaced several others international standards as IFRS 8, IFRS 16 and IFRS 36. This approach allows us to demonstrate the applicabilityof ROV (Real Options Valuation) method and its application to offshore projects with a high degree of uncertainty, carried out at an early stage and, in particular, for the Arctic offshore projects. For illustrative purposes two possible deposits were taken on the shelf of the Barents Sea and the Kara Sea. For these two illustrative examples of the fields in the above sea waters in accordance with the climatic conditions, taking into account the current tax and investment regimes three types of option were designed: to stop the project, to delay the project and to expand the project. The main purpose of this work is to show the applicability of various models of real options for offshore development projects through the examples in the Arctic seas at the stage of prospecting and exploration. There is also the objective to show how the techniques of project management can be agreed under the rules of reporting standards reporting for companies operating according to IFRS 6 standard.

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.
The paper examines the principles for the supervision of financial conglomerates proposed by BCBS in the consultative document published in December 2011. Moreover, the article proposes a number of suggestions worked out by the authors within the HSE research team.

At present many industries reveal tendency for setting up of vertically integrated companies (VIC) the structure of which unites all technological processes. This tendency proved its efficiency in oil industry where coordination of all successive stages of technological process, namely, oil prospecting and production -oil transportation - oil processing - oil chemistry - oil products and oil chemicals marketing, is necessary. The article considers specific features of introduction of "personnel management" module at enterprises of oil and gas industry.
