Управление требованиями при реализации ИТ-проектов
In the paper an approach to modeling of requirements management process associated with IT projects is considered. The requirements management model includes three stages. The first stage is related with the choice of business requirements, which are described in the project solution and define the project scope. The second stage includes development of a model that is associated with accepting, rejecting, clarification or classification as ‘additional task’ for every of incoming user requirements. On the third stage for all the accepted user requirements priorities of system requirements are formulated; these priorities are subsequently used for project planning. The decision making models are based on the methods of analytic hierarchy process (AHP) and analytic network process (ANP), as well as on SuperDecisions decision support system.
The Modeling of problem situations is a very important issue in decision-making theory. Actually, there are no decision support systems which include decision making methods under risk and uncertainty. The main advantage of proposed approach is ability to process dependences and feedbacks which may exist between conditions, sub-conditions and their realizations.
The increase of supply chains efficiency requires optimization of all types of logistic operations and functions. One of such functions is a choice of intermediaries (carriers, freight forwarders, suppliers, service enterprises etc.). The article discusses the analytical and expert approaches which serve as a basis to choose the intermediaries; along with it, in the article a comparative evaluation of choice expert methods is done: point-rating assessment, analytic hierarchy process and the general algorithm for selecting; the conclusions have been drawn about the applicability of each method
This paper presents an approach for developing Linux interface standards aimed to improve portability of applications among different Linux distributions. The approach is based on usage of database-driven informational system that simplifies creation and maintenance of interface standards by standardization committees and their usage by application and distribution developers. A logical model of interfaces between Linux applications and distributions is described which is used to design schema of the informational system's database.
This paper presents an approach of developing a special environment to help application developers to create programs compliant with some interface standard. The paper suggests a design of the informational system aimed to make it easier to develop and to maintain such an environment on the basis of the existing systems, with necessary modiﬁcations in the areas concerned by the standard. To store information about existing systems and to facilitate their modiﬁcation, it is suggested to use a database with a set of accompanying tools. Necessary aspects of the database schema design are described, as well as some aspects of the tool architecture.
A new hierarchical model of decision making under multiple criteria that form a multilevel system is proposed. With this model, one can use approaches and methods of the criteria importance theory to collect information about the importance of criteria and use it to analyze practical multicriterial decision making problems in a correct way.
In this paper we consider choice problems under the assumption that the preferences of the decision maker are expressed in the form of a parametric partial weak order without assuming the existence of any value function. We investigate both the sensitivity (stability) of each non-dominated solution with respect to the changes of parameters of this order, and the sensitivity of the set of non-dominated solutions as a whole to similar changes. We show that this type of sensitivity analysis can be performed by employing techniques of linear programming.
The paper examines the structure, governance, and balance sheets of state-controlled banks in Russia, which accounted for over 55 percent of the total assets in the country's banking system in early 2012. The author offers a credible estimate of the size of the country's state banking sector by including banks that are indirectly owned by public organizations. Contrary to some predictions based on the theoretical literature on economic transition, he explains the relatively high profitability and efficiency of Russian state-controlled banks by pointing to their competitive position in such functions as acquisition and disposal of assets on behalf of the government. Also suggested in the paper is a different way of looking at market concentration in Russia (by consolidating the market shares of core state-controlled banks), which produces a picture of a more concentrated market than officially reported. Lastly, one of the author's interesting conclusions is that China provides a better benchmark than the formerly centrally planned economies of Central and Eastern Europe by which to assess the viability of state ownership of banks in Russia and to evaluate the country's banking sector.
The Working Paper examines the peculiarities of the Russian model of corporate governance and control in the banking sector. The study relies upon theoretical as well as applied research of corporate governance in Russian commercial banks featuring different forms of ownership. We focus on real interests of all stakeholders, namely bank and stock market regulators, bank owners, investors, top managers and other insiders. The Anglo-American concept of corporate governance, based on agency theory and implying outside investors’ control over banks through stock market, is found to bear limited relevance. We suggest some ways of overcoming the gap between formal institutions of governance and the real life.
At present many industries reveal tendency for setting up of vertically integrated companies (VIC) the structure of which unites all technological processes. This tendency proved its efficiency in oil industry where coordination of all successive stages of technological process, namely, oil prospecting and production -oil transportation - oil processing - oil chemistry - oil products and oil chemicals marketing, is necessary. The article considers specific features of introduction of "personnel management" module at enterprises of oil and gas industry.
