In present study the problem of an alarm systems optimization was presented and the stages of the multicriteria structured optimization method in cost-functional characteristics of the alarm system were also described. The method represents a combination of the proposed reflection and selection schemes in the genetic algorithm that solves the extreme combinatorics problem.
In the work some problem receiving the elements of the bimatrix hierarchical non-zero sum game is presented. In this aim the Stackelberg duopoly model was used. To explain a proposed method the example concerning two mining enterprises output a coal is discussed.
There is suggested a method for the trust level establishment to the nodes of distributed computer systems (DCS) taken into account the dynamics of the information value changing and with the in-time records of the security incidents from the nodes. The proposed method of the DCS nodes rating establishment allows adaptively and during the DCS functioning to determine a safety configuration of resources...
The paper presents and investigates the method of network encoding in the residue number system for usage in wireless sensor networks. The method of encoding provides increase of total network bandwidth by choosing coprime digit capacity different modules and different routes of transmission residues.
The conceptual evolution of entrepreneurial leadership is at its early phase. Current studies exploit predominantly the leadership literature, mainly the transactional and transformational leadership approach. The paper focuses on entrepreneurial leadership approach in the context of effective support for exploitation of opportunities. I suggest that the concept of entrepreneurial leadership supports...
Designing the neural network detector of attacks using the vector quantization is considered in this paper. It's based on improved method for hierarchical classification of computer attacks and the information compression using the principal component analysis and combining the neural network detectors.
This paper presents a way to rescue traditional branches of Silesian industry based on the use of restructuring of mining and metallurgy. In recent years crisis has shaken the stability of many industries, including Silesian industry. To improve their condition, they began to use tools to rationalize resources and streamline internal processes more frequently. One example of such actions is restructuring...
The discussions on the energy transition, the involvement of households as decentralized energy providers and the reduction of energy costs show an area of conflicts, in which they act as driving force on Smart Grids. In this regard Smart Grids are seen as a key element to address the former mentioned challenges. This paper continues the public discourse concerning Smart Grids and displays it from...
Business Intelligence promises improved decision making. To meet the changing business requirements, BI has to reduce latency between data acquisition and decision. As a result of growing needs, concepts like Real Time, Active, Operational, Business Performance Management or embedded BI are introduced in the literature. Nevertheless, the technical implementation prevents the realization of these concepts...
In Germany roughly 15.000 tonnes of batteries are recycled every year. New challenges arose as more and more lithium-based batteries entered the market. This article deals with the reverse logistics of lithium-based device batteries and is part of the research project “HybrideLithiumgewinnung” from 2011 to 20131. Especially logistical requirements and safety issues of battery recycling are discussed...
In the article the problems of micro-enterprises (1-5 persons) and small companies, which deal with selling retail and they must adapt to changes in the environment, which are caused by the large number of newly created large-format stores are presented. The paper shows how to use selected quality tools to define new business strategy for micro-enterprise and reorganization of the company.
The international financial? This paper provides an empirical way for the identification and valuation of implicit crisis of 2007 - global systemically important banks receives debt funding cost advantages of more than 2011 showed that when it comes to the crunch, governments bail out their banks. The implicit insurance against insolvency results in better ratings and lower funding costs for banks...
This event study contributes to answering the question of how market participants (re-)act and how prices adjust to (information on) recent events of a strategic dimension. Focusing on the Italian bank UniCreditS.p.A., which has been involved in numerous M&As of European banks, such as the Polish Bank Pekao and the German HypoVereinsbank, we analyze the price movements of UniCredit shares caused...
This work investigates advantages of ontologies as the means for semantic integration of management activities. Semantic technologies are recently recognized as crucial management technologies in domains, which intensively exploit ICT and automation. Ontologies facilitate intra- and inter-organizational integration of different layers, functions, domains and processes of management. Ontologies enhance...
Ontologies enjoy growing interest as facilitators for intra- and inter-organizational semantic integration of different management activities in the ICT and automation intensive industries. This work provides a proposal of core ontology that addresses the operational level of discrete manufacturing and logistics processes. Although only partial research results are presented, they go beyond published...
This article demonstrates research results in the field of biometric authentication. The main part of the article is about qualitative and quantitative characteristics of fingerprint biometrics. The research were carried out on the population of 100 users and the characteristics were presented for enrollment and verification templates in terms of number of minutiae points and the quality of fingerprint...
The paper presents the possibilities of computer-aided mind mapping for the creation of a platform of innovation in initial stage of the life cycle of biometric systems. In the first part of the article we present mind map method and information tools to exploit the potential of distributed processing in the implementation of on-demand platform innovation biometric system. In the second part of the...
When company makes decision about different strategies or investments and want to take into account not only quantitative but also qualitative data, AHP methodology can help and make evaluations of all important criteria easier. In conclusions of this paper AHP methodology is defined as the tool of decision making in situation when it is difficult to evaluate and compare all data. As the result of...
This paper presents decision support system for estimation of patient's general state, with particular stress laid on cardiovascular and pulmonary diseases. It works in conjunction with a standard medical monitor, which provides asset of input signals (for development stage signals are also simulated). The signals are preprocessed and analysed by a set of algorithms, the core of which is based on...
