Critical factors of implementation and operations of personal information systems
Zápotočný, Matej ; Buřita, Ladislav (referee) ; Jašek, Roman (referee) ; Koráb, Vojtěch (referee) ; Sodomka, Petr (advisor)
This dissertation thesis identifies critical factors of implementation and operation service of Human Resource Information Systems with all its specifics. In detail, the lifecycle of the system is described, system elements and types of organizations that might use it. The thesis aimes at four hypotheses that try to confirm or reject the importance of usage of Human Resource Information Systems in companies of various sizes on Czech and Slovak market. The thesis also describes detailed feedback of company representatives in areas of benefits and usage of these systems and presents a list of critical factors that were discovered and confirmed during the preparation of the thesis and related research.

Aspects of Inventories in Retail Business: Models of Natural Shrinkage and Accidental Losses of Retail Stock
Beranová, Michaela ; Solař, Jan (referee) ; Žufan, Pavel (referee) ; Buřita, Ladislav (referee) ; Fedorová, Anna (advisor)
The dissertation thesis deals with the problem of relevant volume of natural shrinkage and accidental losses of retail stock quota calculation. In frame of the dissertation thesis, factors affecting an extent of accidental shortage of inventories in retail business are investigated here. Then, possible approaches to a calculation of relevant volume of such a quota are recognized as well. By its scope, the dissertation thesis reacts on a problem that exists within the income taxes law since 1995, but any conceptual solution of this problem is still missing. This current problem that is felt especially in retail business is right the problem of relevant volume of a quota of natural shrinkage and accidental loses calculation. The dissertation thesis is based on wide research that has been done in both, in retail businesses and on the side of tax administration too. On the basis of this research’s outcomes, the main factors affecting an extent of accidental losses of retail stock have been determined. Then these factors and evaluation of their influence became construction elements of two mathematic models for the calculation of relevant volume of a quota of natural shrinkage and accidental losses of inventories in retail business. These models are the model that is based on the statistic method of multiple regression and the model based on the fuzzy logic, respectively on the fuzzy mathematics. For the conclusion of the dissertation thesis, both models are discussed from the point of their relevance as well as from the view of their practical application. Theoretical and practical contributions of the dissertation thesis are also concluded here along with an outline of possible future research in this area.

Prediction in Projects using Markov Chains
Doležal, Jan ; Buřita, Ladislav (referee) ; Kreslíková, Jitka (referee) ; Lacko, Branislav (advisor)
This thesis is focused on possibilities of a project development prediction and a decision support for managers of those projects, which is an up to date topic in the present time turbulent environment. Project is understood as a stochastic process with discrete states and discrete time in this thesis. This approach could be represented by discrete moments of finding out project state. Project is compared to a finite automaton and Markovs chains are subsequently used. State model of the project based on Earned Value Management method is created in the proposal part of this thesis and there are state transitions probabilities. There are adjustments of the model designed consequently so the model is capable to fit some concrete situation closely. Designed proposals are tested in different situations to prove their value in the experimental part of this work.

Support for IT projects and IT projects portfolio through social networks analysis.
Měsíček, Libor ; Molnár, Zdeněk (advisor) ; Buřita, Ladislav (referee) ; Vejlupek, Tomáš (referee) ; Ritschelová, Iva (referee)
This doctoral dissertation focuses on the area of IT projects portfolio management and IT projects. Dissertation summarizes development of IT projects portfolio management, its benefits, problems, and integration of IT PPM philosophy into selected widely use methodologies and IT frameworks. Further work summarizes developments and main findings of social networks analysis and relevant findings from psychological and sociological field, team work and process of organization. Also presents results of two surveys, on their basis have been formulated conclusions and recommendations. The main part of the work focuses on design of additional processes for MMDIS ŘIP mainly by use of social networks analysis to support the selection of the appropriate staff to selected positions in an IT project. Furthermore, the proposal presents categorization of IT roles according to selected metrics of social network nodes.
