In this paper CASE-technology METAS intended for development of distributed dynamically adaptable information systems is presented. This technology is based on interpretation of the multilevel models describing information system and its domain from the various points of view and at different levels of abstraction. New models expanding functionality of information system can be developed on the basis of existing models.
The study of existing monitoring systems is topical, because at the present level of development the transition to information society and knowledge economy becomes one of the key elements of national strategy aimed to increase country's competitiveness in the international market. There are many index systems that study the nature of this phenomenon and compare countries by the level of digital development. To ensure objective evaluation of innovation capacity the analysis of current monitoring systems applied in measuring the development of ICT and e-readiness together with data collection was suggested.
This article is focused on development trends analysis of international and Russian statistical standards and methodological approaches to organization of surveys on the use of ICT in households and by population. Research trends for the new specialized sample survey of population on the use of ICT are suggested.
There are collected in the Conference proceedings the papers and the reports being presented at the XVII International scientific-technical conference and Russian scientific school of young scientists and specialists "System problems of reliability, quality, mathematical modeling and infotelecommunication technologies in innovative projects (INNOVATIKA-2012)". The actual problems of new apparatus research, IT- technologies development, enterprises control improvement, universities innovative development are considered.
In this book, the impact of modern social media on the development of management system in the hospitality and tourism industry is examined. The present research project was elaborated in two subsequent phases. During the first research phase the localization of the apparatus, methodology, study design, questionnaire and methodology for the Russian version of the research project were carried out. That was done based on the courtesy materials recently completed project by a Center for Hospitality Research Cornel the United States. The second project phase was aimed at identification of the specifics of the Russian consumers perception towards the use of social media for planning their trips.
The paper focuses on the application of web-realted technologies to teaching and learning the English language in HSE. Much attention is paid to the variety of information communication technologies (ICT) and LMS products implemented by the authors of the paper to educational process.
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
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.
