O problémech seřazení při řízení servisních operací
Lín, Václav ; Vomlel, Jiří (advisor) ; Jiroušek, Radim (referee) ; Kouba, Zdeněk (referee) ; Ottosen, Thorsten Jorgen (referee)
The subject of the thesis belongs to the field of operations management. We deal with sequencing problems arising when there are multiple repair operations available to fix a broken man-made system and the true cause of the system failure is uncertain. It is assumed that the system is formally described by a probabilistic model, and it is to be repaired by a sequence of troubleshooting operations designed to identify the cause of the malfunction and fix the system. The challenge is to find a course of repair which has minimal expected cost. We study several variants of the problem proposed in the literature. We analyze computational complexity of those variants, apply integer linear programming to one variant of the problem, and examine the relation to machine scheduling.

Mathematical Programs for Dynamic Pricing - Demand Based Management
Hrabec, Dušan ; Karpíšek, Zdeněk (referee) ; Hoff, Arild (referee) ; Haugen, Kjetil Kare (advisor)
Tato disertační práce se zabývá vývojem, modelováním a analýzou poptávkově orientovaných úloh, které zahrnují marketingová, operační a logistická rozhodnutí. Úlohy jsou zvoleny tak, aby mohly být dále rozšířeny o koncept tzv. dynamického oceňování a jiných dynamických marketingových rozhodnutí. V práci jsou využity dvě základní poptávkově orientované úlohy: a) úloha kolportéra novin, která je zvolena pro její jednoduchou formu a která tak slouží jako nástroj pro ilustrativní ukázky rozhodovacích procesů v podobných typech úloh, a b) úloha návrhu dopravní sítě, kde jsou využity některé výsledky a znalosti získané při řešení úlohy kolportéra novin. Kolportér (či obecně maloobchodník) čelí náhodné poptávce, která může být postupně ovlivněna oceňováním, marketingovými (tj. reklamními) rozhodnutími a nakonec jejich kombinací. Poptávka obsahuje tedy náhodnou složku, která je pomocí přístupů stochastické optimalizace modelována ve specifickém tvaru (tj. aditivní či multiplikativní tvar). Závislost cena-poptávka je zachycena pomocí nelineární klesající poptávkové funkce, zatímco (vhodná) reklama vede ke zvýšení poptávky (běžně rostoucí s-křivka či konkávní funkce). Výsledky získané při řešení úlohy kolportéra novin s oceňováním jsou následně využity v úloze návrhu dopravní sítě. Tato stochastická úloha je modelována (reformulována) pomocí dvou přístupů stochastické optimalizace: wait-and-see přístup a here-and-now přístup. Jelikož tato implementace vede na lineární či nelineární celočíselnou (navíc scénářovou) úlohu, jsou v práci zmíněny taky výpočetní nástroje. Autor pro řešení používá (původní) tzv. hybridní algoritmus, což je kombinace heuristického (genetického) algoritmu a nástroje optimalizačního softwaru. Potenciální aplikace sestavených modelů, obzvláště v oblasti odpadového hospodářství, jsou diskutovány v závěrečné části disertační práce.

Significant factors influencing the social rehabilitation of mentally ill
BAUERNÖPLOVÁ, Alexandra
Mental illness significantly influences all aspects of life. Mental health care goes beyond horizons of medicine and becomes the object of interest of society-wide importance. This thesis is devoted to people with a psychotic disorder. It is focused on their subjective view of themselves, human relations and perspectives of their lives. The theoretical part of the bachelor thesis defines basic concepts and characteristics of psychotic disorders. Social problems of human life with psychotic illness, self-stigmatization question and the impact of the disease on family members is summarized in the next section. Following part is devoted to the status of the mentally ill in society, social issues connected with mental illness, their life perspective and communication problems which face mentally ill persons. End of theoretical part deals with the areas of complex psychiatric, psychosocial and community care, including psychiatric care reform, which is currently being very slowly implemented. The practical part includes qualitative research aims, research questions and methods of data collection. The research group consisted of people with psychotic illness. The data were obtained through interviews. The resulting audio data have been transferred by verbatim transcription into written form and processed by open coding. Subsequently, all data were analyzed and interpreted most complex and interrelated in story form.

Data quality in the business information database environment
Cabalka, Martin ; Chlapek, Dušan (advisor) ; Kučera, Jan (referee)
This master thesis is concerned with the choice of suitable data quality dimensions for a particular database of economy information and proposes and implements metrics for its assessment. The aim of this paper is to define the term data quality in the context of economy information database and possible ways to measure it. Based on dimensions suitable to observe, a list of metrics was created and subsequently implemented in SQL query language, alternatively in a procedural extension Transact SQL. These metrics were also tested with the use of real data and the results were provided with a commentary. The main asset of this work is its complex processing of the data quality topic, from theoretical term definition to particular implementation of individual metrics. Finally, this study offers a variety of both theoretical and practical directions fort this issue to be further researched.

The Czech Digital Library - aggregation and dissemination of digital content from the Czech libraries
Lhoták, Martin
The goal of the Czech Digital Library is to aggregate content of digital libraries in the Czech Republic. It serves both as a common interface for end users and as a primary national data provider for other national and international projects, especially for Europeana and for the Central portal of the Czech libraries - KNIHOVNY.CZ. Tools to support complex digitization processes which include production, workflow monitoring, dissemination and archiving are developed as an open source in the frame of the project. The software solution for digital library - Kramerius system - is used in more than 30 libraries in the Czech Republic and provides access to tens of millions digital objects. ProArc - system compatible with national and international standards is used in several libraries for digital document production. With regard to the archival part of the solution, standards for long term archiving, such as the OAIS model, are implemented in cooperation with Archivematica system.
