The Evaluation in Figure Skating from the View of the Decision Making Theory
Erbsová, Markéta ; Dlouhý, Martin (advisor) ; Nečas, Dalibor (referee)
The evaluation methods of competitors in figure skating are the key problem of this sport. The 6.0 system of evaluation was in use until the year 2004. In such system referee compares competitors one by one and decides on the rank. The 6.0 system can be described by method of Expert Judgment and/or Group Participation. In year 2004 International Skating Union introduced the new system. In this new system is in the role of the decision maker mainly the competitor not the referee. The competitor chooses elements of his program which maximized the total point benefit. We can find out the point value of every element in SOV -- Scale of Values. Nowadays the skater can decide according to the Decision Making under Multiple Criteria theory, we use Weighted Sum Approach method which is sufficient for our purpose. In this thesis both systems are going to be explained on particular cases and linked with methods of decision making theory.

New product installation simulation
Medonos, Michal ; Dlouhý, Martin (advisor) ; Kuncová, Martina (referee)
One of the products produced by Motorpal a.s. is a camshaft. Recently, the company signed a contract with Bosch company to produce new types of camshaft. The analysis of the impact of the contract on the production was made by simulation. To perform the simulation it was necessary to map the whole process. The simulation of the current state was made in the first phase. The results shew many uneffectivnesses in the process and lack of capacity of some workplaces. Some changes in the process were suggested and tested with the aid of the simulation. The best results were achieved when the single-item flow was used. In the second phase the production of a new type of camshaft was added to the simulation. Analysis of these results was divided into two parts. The new production was analysed in the first part and it was discovered that the planned capacites are very deficient. The impact of the new production on the current one was analysed in the second part. It shew that this impact is negativ, especially on the duration of production.

Výpočetní aspekty metody maximálního polyedru pro rozhodování při neurčitosti
Rada, Miroslav ; Ivánek, Jiří (advisor) ; Dlouhý, Martin (referee)
Metoda maximálního polyedru je metoda výběru nejlepší varianty pro rozhodování při neurčitosti. Její hlavní myšlenkou je vybrat tu variantu, která bude nejčastěji mít nejvyšší střední hodnotu, pokud zvolíme náhodně vektor pravděpodobností, s nimiž nastanou jednotlivé stavy světa. Stručně je tedy v práci popsána rozhodovací situace za neurčitosti, s důrazem na zmíněnou metodu. Cílem práce je popsat a implementovat algoritmus, jakým metoda maximálního polyedru vybírá nejlepší variantu, a posoudit jeho výpočetní aspekty. Každé rozhodovací variantě přísluší mnohostěn n-tic (vektorů) pravděpodobností, ve kterých je daná varianta nejlepší. Součástí práce je proto popis několika známých algoritmů pro exaktní výpočet objemu mnohostěnu. Protože některé algoritmy vyžadují na vstupu mnohostěn zadaný více způsoby, jsou zahrnuty též některé algoritmy pro přepočet reprezentace mnohostěnu. Jako nejvhodnější metoda výpočtu objemu pro mnohostěny vznikající v metodě maximálního polyedru je zvolena metoda HOT, doplněná pro případy jednoduchých mnohostěnů Lawrenceovou metodou. Jako nejvhodnější metoda přepočtu reprezentace je zvolena metoda LRS. V práci je dále sestaven rozhodovací program, který využívá dostupných implementací zvolených metod. Program je testován na náhodně vygenerovaných rozhodovacích úlohách. Na základě testování jsou odhadnuty meze jeho praktické použitelnosti ? velikost úlohy bez potíží výpočetně zvládnutelné (doba výpočtu cca 30 min) danou implementací je cca 15 variant x 14 stavů světa, přičemž výpočetní náročnost se zvyšuje rychleji s počtem stavů světa než s počtem variant. Konkrétní hodnoty mezní velikosti úlohy samozřejmě závisejí na požadované době odezvy a použitém hardware. V práci je dále provedeno srovnání výsledků rozhodování podle různých kritérií a jsou navrženy některé směry zdokonalení implementace metody maximálního polyedru.
