Управление стоимостью поставок запасных частей для послепродажного обслуживания сложных технических изделий
The article considers the issues of technical product life cycle management in the field of spare parts delivery organization and management within the framework of after-sales service. It provides an examination of a Petri net model, describing the cause-effect relations between events that are linked to delivery planning and management, based on a probabilistic analytical model for after-sales service of technical products and a program-based risk analysis system based on technical and economic criteria. The result of a given model’s performance is planning of an acceptable balance between the cost and quality of products and their current maintenance, which includes detection and minimization of financial risks. An example that illustrates automated planning of spare parts delivery is given. Dynamics of operated technical products’ quantity variation is represented in the integrated graphic type, providing an opportunity to predict an average factor of technical product’s serviceability, determined both by a number of serviceable technical products in a warehouse of the customer and productivity of repair agencies. The earned value method application is proved to be an effective tool for risk analysis of schedule variance in the field of spare parts delivery. Monitoring of the earned value of finances permits to forecast not only the probability of successful completion of spare parts delivery, but also the risks of both cost and schedule variance. An example of automated risk analysis is provided. Estimated coincidence degree of actual cost and planned value is calculated by means of the effectiveness index, which is used to analyze the quality of customer’s subdivisions performance and to correct further functioning. For a selected year, the effectiveness index can be defined and optimized for the predetermined serviceability factor, assigned for every customer during the process of automated planning of spare parts delivery. The approach presented in the article can be considered quite universal, which predetermines an opportunity to apply it in order to provide solutions for product and service life cycle management problems in various organizational technical and economic systems.

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, the 27th International Conference on Automated Planning and Scheduling, took place in Pittsburgh, at Carnegie Mellon University in June 2017.

This monograph is the collection of the selected papers from Gdańsk EuroSymposium 2015 on SAND – Systems Analysis and Design. SAND is the classical field of research and education in the area of management information systems (MIS) or, as it is called more frequently in Europe – Business Informatics, almost from its origins. The objective of the EuroSymposium on Systems Analysis and Design is to promote and develop high quality research on all issues related to SAND. It provides a forum forSANDresearchers and practitioners in Europe and beyond to interact, collaborate, and develop their field. Therefore, there were three organizers of the 8th EuroSymposium on Systems Analysis and Design: – SIGSAND – Special Interest Group on Systems Analysis and Design of AIS, – PLAIS – Polish Chapter of AIS, – Department of Business Informatics of University of Gdansk, Poland.
Agent-based modeling and simulation was applied to investigate a set of problems in the energy context. The paper shows advantages of the agent based modeling approach. The method to define agents-consumers in simulation tool AnyLogic and the approach to simulating investment project risk are suggested.
The paper represents an application of agent based approach for simulation modeling of the energy resources consumption process, aimed for creating forecast of the energy consumption. One of possible methods of defining agents-consumers behavior is shown in this paper. The AnyLogic 6 computer simulation model of demand and consumption was created using this method. This model allows quantitatively evaluating the predicted demand for energy resources and also the probability of particular result.
The paper presents an ontological modelling tool that may serve as a visual editor for the DEMO methodology and simulator of business-processes. The main goal of the study is to develop an instrumental tool that would enable business analysts to describe business processes at ontological level and analyse their performance. In the paper all stages of development process are presented: from building a DEMO meta-model to its transformation into the Petri Net and simulation. The study is an attempt to fill the gap in conditions of the present deficiency of visual editors for DEMO with simulation capacities.
Smoking is a problem, bringing signifi cant social and economic costs to Russiansociety. However, ratifi cation of the World health organization Framework conventionon tobacco control makes it possible to improve Russian legislation accordingto the international standards. So, I describe some measures that should be taken bythe Russian authorities in the nearest future, and I examine their effi ciency. By studyingthe international evidence I analyze the impact of the smoke-free areas, advertisementand sponsorship bans, tax increases, etc. on the prevalence of smoking, cigaretteconsumption and some other indicators. I also investigate the obstacles confrontingthe Russian authorities when they introduce new policy measures and the public attitudetowards these measures. I conclude that there is a number of easy-to-implementanti-smoking activities that need no fi nancial resources but only a political will.
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.

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.
