The authors emphasize that the innovative direction of development of information activities is the integration of Web platforms (social networks and cloud storages) for creating a unified communication space and storage for large amount of information. Tool that provides this development are cloud managers. For library institutions using such technologies will create the favorable and flexible serviceoriented system for providing users with information resources. For determination of free cloud managers and selected among them a benchmark, the methods of benchmarking and expert evaluation were used in the research. The algorithm for operation with every service is given. The following technological capabilities: “integration with cloud storage”, “cloud disk space manager”, “multimedia playback,” “presence of workspace” for collaboration were taken into account. The result of the study is to determine the cloud manager that can serve as a benchmark for providing free cloud services with a wide range of technological capabilities.Item The approach of granular computing and rough sets for identifying situations(Commission of Motorization and Energetics in Agriculture, 2017) Burov, Ye.; Mykich, K.; Lviv Polytechnic National UniversityIn the article are described problems related to creation and maintenance of situational awareness systems. The definitions of concepts of situation and its identification are presented. An approach based on situational knowledge representation with ontological models is selected for attaining situational awareness in complex intelligent enterprise systems, where objects can be in several situations in the same time and some situations are defined imprecisely. Granular computing approach is used for reduction of situational knowledge management complexity. In order to work with situation defined imprecisely, rough set approximations are proposed for situation definition. The usage of mechanisms inherent to ontological modeling for situation representation and reasoning about them are also discussed.Item Using of personalized approach for assessment of the financial condition of the company(Commission of Motorization and Energetics in Agriculture, 2017) Melnykova, N.; Lviv Polytechnic National UniversityThis paper proposes ways of personalization the process of analysis and management of financial flows of the company that provide definition of strategy for business development. In order to ensure the individual approach have been analyzed the methods of optimization of for making strategic decisions and have been identified peculiarities of their application in this area. This allowed to determine several measures to provide for dynamic changes that occur in the financial condition of the company under the influence of implemented solutions and select the most appropriate decisions to change strategy. For successful implementation, the search of strategy should to provide an individual approach to determining the quality of finances management by taking into account the personal data of activity the company. The modern concept of use of computers and information technology and implementation the expert knowledge provides for the creation of intelligent information systems in specific subject areas: management, audit, statistics etc. Therefore, for solving the basic problems is proposed development of intellectual information system of financial management, which will offer the user optimal options, making for strategy development through intellectual component. As the prototype of such a system is the intelligent information system of financial management (IISFM) that is characterized by a set of informational, technical, programmatic and technological means of telecommunication, knowledge bases and data banks, methods and procedures.Item The structure of the system of processing citizens’ appeals(Commission of Motorization and Energetics in Agriculture, 2017) Markovets, O.; Dumanskyi, N.; Lviv Polytechnic National UniversityThis article describes the features of interaction with public authorities.
