This paper presents the fuzzy mathematical model of transfer criteria of distribution network to 20 kV voltage by analyzing the parameters of the distribution network. The model used for the rapid analysis of priority network licensees to determine the order of their funding. As the basis of the synthesized criteria model was accepted a linguistic definition of priority transfer distribution network...
Today, processing integrated information within and between enterprises is increasingly becoming more and more critical, and so is the implementation and evaluation of an Enterprise Architecture (EA). The review of literature on EA evaluation shows several issues. However, the evaluation of EAs has not attracted sufficient attention, and thus, this research area has not been explored thoroughly yet...
A decision support system is developing for solving practical problems of decision alternatives' evaluation on the basis of a network criteria model. The main input data in the DSS are expert pairwise comparison judgments of the model's elements. Different mathematical methods are used in the DSS to evaluate the model, calculate local and aggregated weights of model's elements. It helps to increase...
The paper examines the features of IT-projects and their impact on the management decisions of outsourcing companies in their implementation, as well as demonstrates the necessity to apply simulation models of portfolio management of IT-projects. It introduces a system-dynamic model of IT-project with elements of the cognitive approach as a basis for model management of an outsourcing IT-company as...
In this paper are offered vector-branching diagrams for modeling the TIF processes. Analyzed properties and disadvantages of TIF methods that make it impossible to use certain methods. To solve these problems invited using of subtractive-additive TIF method. Proved effectiveness of their application, by comparing the TIF methods, and the coefficient of efficiency for different bits capacity.
The objective of this paper is to propose the rule-based algorithmic approach for solving problems of faults influence on the service quality in access networks. In this paper the graph oriented model for network and communication services representation, the rule-based system and corresponding output mechanism, the algorithms for the faults impact analysis based on graph traversal schemes are proposed...
Power electronics has become increasingly important as more applications are electrified. Application range from personnel mobile electronics, to home appliance, transportation and renewable energy systems to name a few. Advances in power semiconductors technology combined with demand for higher efficiency, faster, compact systems has revolutionized the industry, and created a high demand for power...
