Using system dynamics and agent-based modeling methods, a simulation model of the FEFD economy is developed. The model is implemented in the AnyLogic system; it makes it possible to investigate the influence of multiple factors influencing the FEFD economy, for example, increasing rates of investment in fixed assets, average wages rates, subsidies from the federal budget, the forecasted price trends of oil, gas, carbon, diamonds and fishing industry products. One feature of the model is the possibility to analyze the dynamics of development of all regions of the FEFD, as well as taking into account the influence of external macroeconomic factors. The decision support system we designed allows us to visualize important characteristics of the FEFD subjects using the map of Russia (GIS) and to save the results of the simulation modelling to the system database. At the same time, we have the possibility of forecasting the dynamics of the Gross Regional Product (a geographic information system) of the Federal District depending on values of the control parameters. Different scenarios of the FEFD development are investigated. The realistic scenario assumes stabilization of prices for the main energy resources (oil, gas, coal) and minerals with simultaneous growth of investments in fixed assets. The pessimistic scenario assumes falling prices for energy, diamonds, fishing products, etc., as well as the reduction in the numbers of the economically active population in the Far Eastern Federal district. The optimistic scenario assumes stable increasing demand and prices for the products of all main sectors of the economy of the Federal District, maintaining current growth rates in industry and agriculture.","PeriodicalId":41920,"journal":{"name":"Biznes Informatika-Business Informatics","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48890419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fomichev","doi":"10.17323/1998-0663.2018.3.20.28","DOIUrl":"https://doi.org/10.17323/1998-0663.2018.3.20.28","url":null,"abstract":"For practical, important tasks in the fields of economics and logistics, as well as in a number of technical applications, it becomes necessary to solve the traveling salesman problem (TSP). Quite often, the features of these problems lead to the traveling salesman problem in asymmetric formulation (asymmetric traveling salesman problem, ATSP). Moreover, in some practical applications it is desirable to obtain an exact solution. One of the known exact algorithms for solving the ATSP is an algorithm that implements the well-known branch and bound method. The known experimental estimates of its complexity on the average are exponential. However, this does not mean that for small dimensions of the problem (currently, no more than 70-75), the expected time for solving the individual problem is unacceptably high. The need to reduce the time for solving individual problems dictated by practice is associated with the use of various modifications of this algorithm, of which a modification that involves storing truncated matrices in the search decision tree is one of the most effective. In this article, the authors rely on this modification. Other possible improvements in the time efficiency of the software implementation of the branch and bound method are related, among other things, to obtaining the initial approximation by heuristic algorithms. As a result, we get a combined algorithm, in which, at the first stage, some heuristics works to obtain the initial solution, from which the branch and bound method starts. This idea has been discussed for a long time, but the problem is that to reduce time, such a heuristic algorithm is needed that delivers a solution close to optimal which will be found quite fast. One of the possible solutions to this problem is the subject of this article. The subject of the research in this article is the choice of the best heuristic algorithm which, when applied, leads to an increase in temporal efficiency in combination with the algorithm of the branch and bound method, and an experimental study of its software implementation in order to obtain an average time for solving individual problems. On the basis of the results obtained, recommendations are given on the limiting dimensions of the problem that allow for an acceptable solution time, something which is of interest in the practical application of this combined algorithm in the tasks of business informatics and logistics.","PeriodicalId":41920,"journal":{"name":"Biznes Informatika-Business Informatics","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2018-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46821233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed algorithm makes it possible to calculate the parameters of the triangular and trapezoid membership functions taking into account the distribution of the variable of interest stored in the database. The algorithm defines the intervals covered by the term bases, so that each interval contains about the same number of values. Upper bounds of the defined intervals are used to calculate the parameters of membership functions. The parameters of the membership functions generated with this algorithm can be easily calculated with the limited computational means of the SQL language. We review the algorithm realizations for the generation of 3 and 5 terms of a linguistic variable based on a sample from a database containing 100 or 500 different values. The membership functions obtained through the algorithm have the required properties of orderliness, completeness, consistency and normality. They do not require further approximation. Unlike the known methods, the algorithm does not require significant computing resources, the use of specialized software, settings configuring, or a training set formation. The algorithm implementation creates opportunities to support fuzzy search queries in relational databases using the means of the SQL language, as limited as they are. Thus, the system’s level of intelligence would be increased, and the user would be provided with the means of search query formulation in a natural language. The linguistic variable terms generated using our algorithm can be used within the framework of a fuzzy rule-based knowledge base of an information system, as well as to perform fuzzy inference.","PeriodicalId":41920,"journal":{"name":"Biznes Informatika-Business Informatics","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2018-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48497430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laskin","doi":"10.17323/1998-0663.2018.3.53.61","DOIUrl":"https://doi.org/10.17323/1998-0663.2018.3.53.61","url":null,"abstract":"The introduction of the institution of cadastral value in the Russian Federation opens up new opportunities in real estate valuation. In this regard, the new focus for appraisers is statistical analysis of multidimensional empirical distributions that were not previously available, because the real estate market does not have pairwise and multidimensional observations concentrated in unified databases. Data of interest to analysts is usually concentrated in different sources from different owners and pertains to different objects. The goal of combining them can be solved by comparing such data with the data of cadastral records, namely the cadastral number as a unique identifier of the object. Since the cadastral value corresponds to each cadastral number, it is possible to compare the cadastral value with important indicators such as the market price of the offer, the transaction price, the rental rate, the annual price indices, the capitalization rate, the discount rate, the trading discount and many other indicators, the formation of which involves more than two random variables. The construction of the model involves the principle of following the prices formed by pair comparisons to geometric Brownian motion, and hence the formation of lognormal population. As it turned out, as a result of large-scale cadastral work carried out in the Russian Federation in 2014, the cadastral value is also subject to lognormal distribution of prices (in each class of objects). For the market value (as the most probable price of the transaction under conditions of perfect competition), this leads to functional dependences from the cadastral value of the power type. Similarly, many other indicators will also be subject to dependences in the form of power functions. Obviously, having a function depending from the various indicators of cadastral value across the set of values, you can set the relationship between the various indicators, which was impossible before the introduction of the institution of cadastral value. This article proposes a method of calculating the trading discount when appraising real estate based on analysis of market statistics and databases of cadastral records. An analytical formula of the dependence of trading discounts from the offer price is proposed. The method allows us to set the level of the discount not only for objects included in an advertising database, but also for any object that has undergone cadastral registration.","PeriodicalId":41920,"journal":{"name":"Biznes Informatika-Business Informatics","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2018-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47088235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The particularity of the approach consists of combining broad understanding of values, aiming at real business tasks at all the levels of enterprise management, and including digital transformations risk management in these tasks. The approach includes both “analog” and “digital” values models, and also employs heterogeneous values models. Values are regarded as a social and economic, corporate and personal phenomenon. Subjectivity, situatedness, relativity, and changeability of values are taken into consideration. The article suggests conjoint consideration of various stakeholders’ (interested parties’) heterogeneous values, among others, of stakeholders affected by digital transformations. The enterprise itself as an economic agent, its owners, employees, enterprise-partners, clients/customers, communities, social organizations, and public agencies might be among the stakeholders considered One of the key requirements is values comparability and the ability to determine the gap between different stakeholders’ values. Other requirements define the constitution of values models and characteristics of models elements. One of the essential results of this research is the developed system of requirements. Besides, the structure of an open multidimensional enterprise values space is suggested as well as the structure of partial and integrated values models placed in this space is presented. The framework for tracing relations between the enterprise components and the stakeholders’ values is proposed, and the possibility of introducing functions assessing conformity and nonconformity of different stakeholders’ values on the integrated values model of the enterprise is demonstrated. The presented system of requirements and models enables building and applying values models which was tested in completed projects. The approach allows enabling sustainable enterprises development under digital economy conditions at the fundamental level by values-directed management. Moreover, it might prove useful for expanding enterprise transformation methods, including their existing value-directed and value-centered variants.","PeriodicalId":41920,"journal":{"name":"Biznes Informatika-Business Informatics","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2018-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42907408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prime objective of this study is to examine the influence of KM processes and capabilities on the performance of small and medium-sized enterprises (SMEs) in Saudi Arabia. KM capabilities comprise people, IT, the organizational structure and the organizational culture, which are measured in this research by T-shaped skills, IT support, the level of centralization, and learning. The other dimension is KM processes, which consist of accessing, generating, embedding, representing, facilitating, using, measuring and transferring knowledge. Moreover, KM performance is measured via two factors: the organization’s financial performance and customer satisfaction. The research reviews previous literature related to the KM components (processes, capabilities and performance) to develop the research model and a number of hypotheses to evaluate the research problem. The data is collected through a questionnaire-based survey completed by a total of 126 managers working in different sectors of Saudi SMEs. With the help of a number of statistical tests, the research study found that that the KM capabilities, IT support, learning culture, decentralized structure and the people of the organization contribute to the success of KM practices or processes, validating the theoretical model.

To develop a company to its full value in the digital environment, it should include an IT department capable of meeting business needs. Evaluation of the current state of the IT department in terms of digital transformation will determine the company’s potential for further development. This article presents a solution to the problem of assessing the IT department’s readiness for digital business transformation by developing a quantitative assessment of the maturity level of the IT department processes for meeting the needs of the enterprise. The approach to solving this problem consists in the joint use of models for assessing the digital maturity of the enterprise as a whole and models for assessing the maturity of the IT department processes and herein is the scientific novelty of the results obtained. At the first stage of the study, based on the analysis of modern information and digital management practices, as well as on the study of approaches to assessing the digital maturity of the enterprise and the processes of the IT department, we developed the requirements for the IT department maturity model of digital business transformation. The study identified the prospects for IT departments that affect its maturity level, developed a model for quantifying each perspective and a model for calculating the minimum level of maturity of the IT department to achieve the expected assessment of the company’s digital maturity. To assess the willingness of IT departments to digitally transform business, a regression equation of IT department maturity level is constructed from the influencing prospects (factors). The results of approbation of the model are presented.","PeriodicalId":41920,"journal":{"name":"Biznes Informatika-Business Informatics","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42574073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such transformations may range from changes of business processes to changes of information systems used to support the business processes, changes in the underlying IT infrastructures and even in the enterprise information system as a whole. The main characteristic of changes in a turbulent business environment and, consequently, in the enterprise information system is unpredictability. Therefore, an enterprise information system should support the operational efficiency of the current business model, as well as provide the necessary level of agility to implement future unpredictable changes of requirements. This article aims to propose a conceptual model of an agile enterprise information system, which is defined as a working system that should eliminate the largest possible number of gaps caused by external events through incremental changes of its own components. A conceptual model developed according to the socio-technical approach includes structural properties of an agile enterprise information system (actors, tasks, technology, and structure). Structural properties define its operational characteristics, i.e. measurable indicators of agility - time, costs, scope and robustness of process of change. Different ways to build such an agile system are discussed on the basis of axiomatic design theory. We propose an approach to measurement of time, cost, scope and robustness of changes which helps to make quantitative estimation of the achieved level of agility.","PeriodicalId":41920,"journal":{"name":"Biznes Informatika-Business Informatics","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46359755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Большая Печерская, д. 25/20E-mail: bulitin@hse.ru Совместный анализ общей структуры онлайн-дискуссий в Интернете и различных психолингвистических характеристик отдельных сообщений является актуальной исследовательской задачей в фундаментальном и прикладном аспектах. Несмотря на успехи алгоритмических методов автоматического анализа сообщений с помощью методов машинного обучения, остаются нерешенными проблемы моделирования динамики структуры дискуссий и характеристик отдельных сообщений при наличии группы автономных авторов. Авторами предлагается использовать для решения этих проблем методы многоагентного имитационного моделирования. В данной работе представлены две многоагентные модели дискуссии, которые позволяют в полной мере учесть характеристики отдельных сообщений и наличие группы авторов с индивидуальными моделями поведения, сформированными на основе анализа реальных онлайн-дискуссий в сети Интернет. Одна из моделей является централизованной в том смысле, что поведение всех авторов идентично и описывается единым блоком управления, зависящим от нескольких параметров. В отличие от централизованной модели, вторая модель является распределенной и характеризуется индивидуализированным поведением каждого автора. Поведение автора в данном случае задается посредством иерархической марковской цепи особой формы. Такая структура модели позволяет не только максимально приблизить процесс ее работы к реальному процессу создания дискуссий, но и обеспечивает возможность сравнения результатов работы моделей с фактическими данными онлайн-дискуссий в Интернете. Важной особенностью предлагаемого подхода к моделированию является активное использование предобработанных фактических данных реальных дискуссий на различных Интернет-площадках. Предобработка данных включает как методы экспертной оценки психолингвистических характеристик (интент- и контент-анализа), так и методы математического статистического анализа. Поэтому в целом исследование является удачным примером междисциплинарного похода к изучению феноменов Интернет-коммуникаций.Исследование выполнено при финансовой поддержке Российского фонда фундаментальных исследований, проект № 16-06-00184 А «Разработка и исследование моделей online-дискуссии на материале обсуждения политических новостей»","PeriodicalId":41920,"journal":{"name":"Biznes Informatika-Business Informatics","volume":"50 5 1","pages":"17-29"},"PeriodicalIF":0.6,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67909602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
