The model is implemented with the use of fuzzy logic. First, fundamental theoretical principles related to the problems of project success rate, fuzzy sets and fuzzy logic are introduced, after which a fuzzy model for project success rate evaluation, including partial sub-models, is presented in the form of a case study which represents the main goal of the article. The fuzzy model is implemented in the MATLAB software environment with the use of the Fuzzy Logic Toolbox application, where it is also verified and further specified. The fuzzy model consists of six input variables which are divided according to their character into three categories in each block (RB1, RB2, RB3) and are separately evaluated. Partial outputs from the blocks (RB1, RB2, RB3) are simultaneously inputs for block RB4, from which there is a single output variable – project success (PS). The RB1 rule block evaluates the situation from the point of view of the state of the project. The RB2 rule block evaluates the total value of project risk. The RB3 rule block evaluates project quality. The RB4 rule block evaluates the total project success rate. Experimenting with the fuzzy model allows simulation of the uncertainty that is always involved in projects. The case study introduces an overall diagram of the fuzzy model, the input and output variables, including their attributes, and the evaluation rules of the four rule blocks. The proposed fuzzy model is used to evaluate project success primarily in the implementation phase, then repeatedly after each phase of the project is completed. This provides project managers with a tool that allows relatively rapid evaluation of the success of the project and the opportunity of applying appropriate measures in good time if necessary.
- ItemComparative assessment of external costs and pollution taxes in Baltic States, Czech Republic and Slovakia(Technická Univerzita v Liberci, 2016-12-05) Štreimikienė, Dalia; Ališauskaitė-Šeškienė, Ilona; Ekonomická fakultaExternal costs are the main market failure. Pollution taxes and other flexible market instruments are applied to internalise external costs of atmospheric emissions. Subsidies to renewable energy technologies in the form of Feed-in prices are also applied to internalize positive external benefits associated with use of renewable energy sources for energy generation as these technologies have lower life-cycle emissions of classical pollutants and GHG emissions in comparison with fossil fuel based energy generation technologies. The paper reviews and compares external costs of atmospheric pollution and pollution taxes in Baltic States, Czech Republic and Slovakia and assesses the level of internalization of external costs and their impact on atmospheric emissions of classical pollutants in these countries. The literature review allows generalizing results of external costs assessment and their internalization issues. The paper analyses and compares external costs of atmospheric pollution in Baltic States, Czech Republic and Slovakia together with atmospheric pollution taxes and other policy measures used to internalise external costs of atmospheric pollution in Baltic States and Czech Republic and Slovakia. The analysis of trends of atmospheric pollution by classical pollutants in Baltic States and Czech Republic and Slovakia is provided and policy recommendations based on the main findings of analysis conducted were developed.
- ItemInvestment opportunities for family businesses in the field of use of biogas plants(Technická Univerzita v Liberci, 2016-12-05) Myšáková, Darina; Jáč, Ivan; Petrů, Michal; Ekonomická fakultaThis article deals with the economic evaluation of biogas plants which are one of the most important renewable energy sources in the Czech Republic. They provide a stable supply of electricity and heat without polluting the environment by emissions. They significantly contribute to the environmental protection. For businesses, this renewable source of energy means financially a very profitable, safe and a fast repayable investment. These investments are a big opportunity mainly for a family type of business which especially in municipalities in rural areas performs a variety of other economic and non-economic objectives including the use of biomass. Opportunities of family businesses are in agreement between the parties, involvement of family members, knowledge of technology and know-how, flexibility in labor, time and money, long-term planning, stable corporate culture, speed in decision-making, proximity to local markets, pride and credibility, efficiency, productivity, focus on quality. In recent decades, corporate social responsibility has been at the forefront of marketing tools of businesses and is often associated only with the ethical standards that, among other things, seek to minimize negative impacts on the environment This article focuses on their basic characteristics, maps specific ways which the company can use for their financing and analyzes the profitability (yield) and return on these investment projects.This development can focus more on strengthening family businesses in municipalities of a rural type where many owners of forests or larger plots can take advantage of investment opportunities and stabilize the economy of their businesses. However, even more side effects such as new jobs and partial subcontracts from other family businesses or other companies can be noted.
- ItemThe paradoxes of creativity management(Technická Univerzita v Liberci, 2016-12-05) Kačerauskas, Tomas; Ekonomická fakultaCreativity is a very important aspect of market economy. Creativity is an ambivalent and contradictory phenomenon that covers both positive and negative aspects. As a result, management of creativity faces some paradoxes. The paper deals with 10 paradoxes of creativity management including one grand paradox (GP) and nine minor paradoxes (MP). By stimulating creativity, the managers risk to provoke the disobedience for their instructions including an instruction to develop creativity (GP). Successful period of an organization is an obstacle to develop the creative ideas (MP1). A radical implementation of creative ideas threatens the identity of organization (MP2). Creativity provokes the conflicts in organization (MP3). Every inventor or innovator tries to negate his (her) social environment that has educated and stimulated him (her) (MP4). Although hard management kills creativity, the latter needs sometimes very hard decisions (MP5). The worse the results are, the more creative the decisions in organization are (MP6). Organizations should manage both quantity and quality (MP7). Organization needs not only management of knowledge but also management of ignorance and naiveté (MP8). The managers should forget the past success of organization and think about future end of it (MP9). The main aim of this paper is to describe these paradoxes. Another aim is to present the different approaches towards creativity management. Finally, the paper seeks to dethrone a naive attitude that creativity in economy solves all possible problems. The biggest challenge to the management is the very creativity.
- ItemDesigning modern informatics education for future managers and advanced users according to their knowledge base(Technická Univerzita v Liberci, 2016-12-05) Révészová, Libuša; Ekonomická fakultaThe main question we are dealing with is how to teach/educate the future managers – advanced users of business informatics, ICT and information systems. As a very important step in determining the content and method of teaching we consider an evaluation of the knowledge base of students who enter the first year at the Faculty of Economics Technical University of Košice. In the first seminar in subject called Informatics I students fill in questionnaires which are focused on their general knowledge of informatics/computer science and basic terms of IS. In the paper we present evaluation of our questionnaire survey in the period 2003-2014. Conclusions formulated in the paper are directly relevant for teaching realized on the Faculty of Economics, Technical University Kosice. In the process of questionnaire creation we drew from generally valid documents for secondary schools in Slovakia. In the sample of respondents there were mostly graduates from Eastern Slovakia Region therefore this allows us to assume that knowledge base and ICT competences on the other faculties especially in our region with non informatics focus would copy the described trends. We also present our innovative manner of informatics education based on modeling, simulation and on a well known opinion that “no kind of teaching can replace the personal experience". As a dominant form we use problem-oriented project teaching. Students find themselves in a position of a manager of a virtual company, at project of specifying users’ requirements The paper deals with the experience in teaching, we present recommended structure of the user requirements project and we also discuss the body of knowledge and methods which have been implemented into the subject Informatics II. In the proposed innovative way of teaching we are trying to transform solving problem process into an active process of cognition.
