Total cost optimisation model for logistics systems of trading companies
The purpose of this research is to develop a model for optimising total logistics costs of a trading company. To achieve the aim, a logistics system has been analysed and, as a result, major subsystems, logistics processes and most substantial logistics costs have been identified. The results of the analysis have been used to elaborate conceptual and structural optimisation models. They have been further used to develop a mathematical model considering both direct and indirect costs. The mathematical model has been tested numerically, so a table model has been worked out. The research has resulted in a Boolean linear programming model for determining the values of the indicators of the order cycle time and stock level, ensuring optimal total logistics costs of a trading company. Strategic objectives have been decomposed into the goals of individual departments, expressed with the target values of the indicators of lead time and cargo turnover.
In article value of network cooperation of links logistic systems is stated and the key directions of changes of branch structure taking into account international practice and interbranch specifics are reflected, the main terms are defined, components of cumulative efficiency of cooperation of links logistic systems are allocated and the mathematical model of minimization of costs is presented at interbranch level.
Using the city logistic concept, we have formulated the main principals of designing of the logistic systems aimed at providing resources for city enterprises and citizens. As an assessment of the city logistic systems, there have been developed an integral criteria of effectiveness which takes into account logistic costs, SNIPS (shipped not invoiced products or services), ecological damage related to different ways of supplies and types of transportation means being used.
This article discusses the creation and application of the machine learning approach for the dynamic control of the following parameters of logistic systems: the level of warehouse residues and the delay time of the supplier's machine when the goods are delivered to the company's warehouse. For the analysis of these parameters, two classifiers were created using the logistic regression method, which were able to classify the current state of the system and the level of threat in performing certain operations. For each parameter, a training and test sample were created, which were later used for training and testing classifiers. After completing of training, the monitoring system was able to classify new data in real time that had not been previously reported, which allowed to define the system state for an indefinite period of time. For the classifier, heuristically were created classification rules, which most accurately reflect the state of the logistics system
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.
