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.

ICAPS 2017 is part of the ICAPS conference series, the premier forum for exchanging news and research results on theory and applications of intelligent and automated planning and scheduling technology.
AnnotAtion. In the article authors compare two fundamental approaches to order fulfillment. First one is traditional functional approach where «order management» is a logistics function. On the other hand, process centric approach considers «order fulfillment» like key business process in supply chain management. Researchers investigate typical problems in core steps of order fulfillment process and its key performance indicators. In the context of process centric approach authors suggest allocation of responsibility between main supply chain agents on strategic and operational level of «order fulfillment» process. Moreover, researchers identify coordination mechanisms on the main steps of analyzed process. In addition, they give comparative analysis of different approaches to efficiency evaluation of order fulfillment process.
The textbook has passed practical tests and written on the basis of the readable authors for many years. Presented in textbook materials give students orientation in the solution of many practical problems in a number of areas, constitute the initial level to obtain a broader and deeper education in the field of probability theory. The book provides an overview of the theory of stochastic processes, detailed material on the theory of Markov processes with discrete time (Markov chains) and continuous-time. In addition to the solved problems for each Chapter of the textbook suggested problems to solve and theoretical questions to test the quality of the learning material.
A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traffic is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the final node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a finite-dimensional system of differential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of differential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
The geographic information system (GIS) is based on the first and only Russian Imperial Census of 1897 and the First All-Union Census of the Soviet Union of 1926. The GIS features vector data (shapefiles) of allprovinces of the two states. For the 1897 census, there is information about linguistic, religious, and social estate groups. The part based on the 1926 census features nationality. Both shapefiles include information on gender, rural and urban population. The GIS allows for producing any necessary maps for individual studies of the period which require the administrative boundaries and demographic information.
Existing approaches suggest that IT strategy should be a reflection of business strategy. However, actually organisations do not often follow business strategy even if it is formally declared. In these conditions, IT strategy can be viewed not as a plan, but as an organisational shared view on the role of information systems. This approach generally reflects only a top-down perspective of IT strategy. So, it can be supplemented by a strategic behaviour pattern (i.e., more or less standard response to a changes that is formed as result of previous experience) to implement bottom-up approach. Two components that can help to establish effective reaction regarding new initiatives in IT are proposed here: model of IT-related decision making, and efficiency measurement metric to estimate maturity of business processes and appropriate IT. Usage of proposed tools is demonstrated in practical cases.
The manual is intended for students of Department of computer engineering MIEM HSE. In the textbook based on the courses "Economics of firm" and "the development strategy of the organization." Discusses the key conceptual and methodological issues of the theory and practice of Economics and development planning of the organization. The use of textbooks will enable students: to analyze key performance indicators, and use the tools of strategic analysis with reference to concrete situations in contemporary Russian and international business. Special attention is paid to the methods and systems of information support of the life support functions of business organizations and management methodology of innovation and investment. An Appendix contains source data for analysis of competition in a particular industry.
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
Over the last two decades national policy makers drew special attention to the implementation of policy tools which foster international cooperation in the fields of science, technology, and innovation. In this paper, we look at cases of Russian-German collaboration to examine the initiatives of the Russian government aimed at stimulating the innovation activity of domestic corporations and small and medium enterprises. The data derived from the interviews with companies’ leaders show positive effects of bilateral innovative projects on the overall business performance alongside with major barriers hindering international cooperation. To overcome these barriers we provide specific suggestions relevant to the recently developed Russian Innovation Strategy 2020.
