In information systems security, the objectives of risk analysis process are to help to identify new threats and vulnerabilities, to estimate their business impact and to provide a dynamic set of tools to control the security level of the information system. The identification of risk factors as well as the estimation of their business impact require tools for assessment of risk with multi-value scales according to different stakeholders' point of view. Therefore, the purpose of this paper is to model risk analysis decision making problem using semantic network to develop the decision network and the Analytical Network Process (ANP) that allows solving complex problems taking into consideration quantitative and qualitative data. As a decision support technique ANP also measures the dependency among risk factors related to the elicitation of individual judgement. An empirical study involving the Forestry Company is used to illustrate the relevance of ANP.
In this paper the exam results of the subject "Applied Mathematics for Informatics" (formerly Methods of Operation Research) from the last 13 years have been analysed. The exam has two parts: written test and oral exam. The grades of the students of the subject have been low for a long time. We would like to know if the low grades are due to the quality of the tests or due to a reducing number of hours of contact teaching. Another reason of low grades can be due to the mathematical character of the subject and to the unpopularity of such kind of subjects. Based on the bad results, students have also initiated a change in the scoring system.This article builds on our paper at the conference ERIE 2013. The main goals of this paper are to find out if the grades have had the tendency to decline during the years and to evaluate the validity, reliability, difficulty, and discrimination power of the tests.
rapid changes in the external environment require the decision-makers to select new approaches and methods of decision-making (Svoboda 2008). information and knowledge systems based on knowledge approach and or/MS methods have an important role in this process. Quality decision support systems and information and communication technologies and the quality of the provided information and knowledge for the decisionmakers are an important source of competitiveness (Šilerová, Kučírková 2008). This quality is based on the user's satisfaction with these systems (Beránková et al. 2008) and their elements as mathematical models. in connection with these facts and with wide-spread theory of knowledge mapping, more and more questions dealing with their practical use arise.Do we need to formalize knowledge? Do we need to formalize its using a knowledge map? What are we to do with a (mathematical) model to consider it as a knowledge map? is the approach of the linear programming model construction (creation) process an analogue to the process of the knowledge map creation? is there any relevant application of this process in agriculture and rural development? Some answers to these questions will issue from the following text. And finally: can we read a solution from a model in the same way as knowledge from a map? Knowledge maps in agriculture and rural developmentZnalostní mapy v zemědělství a rozvoji venkova H. Brožová, T. Šubrt, J. Bartoška Department of Engineering Systems, Faculty of Economics and Management, Czech University of Life Sciences Prague, Czech RepublicAbstract: The possibility of knowledge maps use in the decision-making process in agriculture and rural development is discussed in this paper. Each knowledge map presents a visualization of knowledge using different tools, where a mathematical model can be applied as one of them. The hierarchical structure of a knowledge map conforms to the general structure of a mathematical model. The mathematical model, when successfully solved and correctly read, is a knowledge map in itself. The parallels exist also between the creation process of a mathematical model and of a knowledge map. in general, every phase of a system approach can lead to a special knowledge map. The following paper explains this process and demonstrates it on the farm production structure optimisation problem solved by using a linear programming model. Key words: knowledge formalisation, system approach, decision-making, map creation process, model creation process Abstrakt: znalostní mapy mohou být významným nástrojem při řešení problémů zemědělství a venkova. Každá znalostní mapa vizualizuje znalost pomocí různých nástrojů. Speciálním typem této vizualizace či formalizace může být matematický model, protože hierarchická struktura znalostní mapy odpovídá obecné struktuře matematického modelu. Správně aplikovaný úspěšně řešený matematický model je tedy znalostní mapou. Existuje také paralela mezi postupem tvorby znalostní mapy a matematického modelu. Proces aplikace znalostních map ve formě ma...
Although every problem has multiple solutions, many restrictions and various ways to be addressed, there are also many techniques, methods and approaches proposed by scholars and practitioners that can be implemented to help increase our decision making effectiveness. The Forum will address this issue by engaging participants to reach a group decision using a proprietary web based platform that implements the Group Analytic Network Process (GANP), named WEB ANP SOLVER that is open for academic use. An illustrative case concerning the selection of the best candidate for a job position as a teaching associate based on given profiles and preselected criteria will be used during the Forum. The results of this game will provide significant insights for the group decision making process, explore the proposed techniques and bring out the advantages and disadvantages reported in literature.
This research identifies the lecturers’ competencies which are the most important from the students’ perspective at the Czech University of Life Sciences Prague and compares students’ opinion and their change over the whole study period. It does not deal with the knowledge competencies of lecturers that students cannot objectively evaluate, but with lecturers’ managerial competencies that affect the organization, forms and ways of teaching. The examined competencies are hierarchically organized into three groups of particular competencies comprising of bipolar characteristics. Based on survey of students at the University, the evaluation of importance of managerial competencies using the Analytic Hierarchy Process was performed. The findings show that Innovative education, Good communication skills, Ability of improvisation, and Democratic way of teaching are the most important lecturers’ competencies from students’ point of view. Surprisingly, Oral based presentation is preferred to IT based one. Knowledge of the most important managerial competencies can help lecturers and universities to increase quality of educational process and attractiveness of the university for students. Keywords. Analytic Hierarchy Process, higher educational institutions, lecturer’s managerial competencies, students’ perception.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
