Управление информатизацией предприятия с использованием архитектурных подходов
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 article deals with a through service-oriented design of integrated information-analytical systems based on architectural approach using ontological modeling framework of the Enterprise architecture. It describes the complex ontological models of the enterprise: a model of meta-ontology, model of the business environment and the ontology of strategic information systems in accordance with the scheme of an enterprise architecture framework, the ontology of strategic decision making
The paper discusses the development of the organizational practices in a Russian university under the influence of the environment. In the latter, the key factors are legislation and regulations of the Ministry of education and science. This influence is ambiguous and varies in different aspects, so to understand combined effect one needs detailed analysis using purposebuilt tools. The paper introduces such tool based on ideas of business model canvas by Alexander Osterwalder and Yves Pigneur and organizational design theory by Henry Mintzberg. This instrument makes it possible to conduct a system analysis of the organizational design of the university, the integrity of this design and its fit to the environmental conditions. In particular, this analysis shows, how the system of restrictions and stimuli, created by the Ministry of education and science leads to the degradation of education quality in a classic university
Innovation is the realization of a creative idea being applied to an existing problem. This application may be either of a new idea or the adoption of an existing idea. As we can see some aspects of Enterprise Architecture development and other activities in large organizations may grow from supposed purely engineering tasks to real research problems. This is a soil for cooperation and co-innovation in research and development that may be of a great value for both science and industry.
The article deals with information technology, in connection with what is developing and information management. Effective planning and implementation of IT strategies today are associated with through service-oriented design based on an architectural approach.
One of the challenging issues of Enterprise Architecture (EA) in large companies is organizing processes of baseline EA development and change management under conditions of steady change that implemented and changed IT solutions introduce. The research paper describes the approach of developing and keeping relevant baseline EA description together with IT project teams using Solution Architecture models. The method is in process of implementation in one of the leading Russian oil and gas companies Surgutneftegas
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.
