Analysis of the Production of Pressure Vessels
Schiller, Pavel ; Jaroš, Aleš (referee) ; Kalivoda, Milan (advisor)
The thesis deals with the optmization of the manufacturing process of pressure vessels. Primarily, the thesis is focused on optimization of bottom and throat forging operations, because only these operations must be performed in a three-shift system, unlike the other operations that are performed in a two-shift system. After the analysis, the inefficient operations have been identified and the goal was to eliminate them. We have found a solution to this situation as an automation of the critcal operation. We have compared the present and proposed solution by capacity calculation. Subsequently, the technical- economic evaluation has been performed which was a basis for the determnation of investment return related to the automation of the critical operation

Goal Programming Models: Theory, Applications, Software Support
Skočdopolová, Veronika ; Jablonský, Josef (advisor) ; Brezina, Ivan (referee) ; Šubrt, Tomáš (referee)
Goal programming is an approach for solving decision problems. The aim of this doctoral thesis is to show the practical use of this approach for solving real problems. The first chapter brings a brief introduction to multicriteria decision making. The second chapter is devoted to goal programming, its history, theory, criticism and also to its practical applications. The third chapter deals with description of a model for optimisation of white mass production. This model utilises the goal programming principle to deal with measuring deviations of raw materials' composition. A part of this chapter is a presentation of OPTIPROT, an application that implements the mentioned model. In the fourth chapter there are described three mathematical models for timetabling at a department level; two multistage models and one complex model. All three models are formulated utilising goal programming. In this chapter there is also described an application that implements the complex model for timetabling.

Optimalizace výroby podniku s využitím nákladových funkcí
Vašíčková, Lucie
The thesis deals with the optimization of the production of a particular industrial enterprise, Armaturka Vranová Lhota plc, with the use of cost and revenue functions for three analyzed industrial valves. In the literary section it provides basic theoretical and methodological foundations on the issue, including definitions of essential terms. The emphasis here is on determination of cost functions and classification of costs, revenues function and optimal size of a company's output in the short term. This section also describes the use of econometric models. The practical part is focused on drawing up individual models of the analyzed products. Based on the developed econometric models, respectively their incremental characteristics, the optimization of production was carried out. In the conclusion section, the results obtained from the individual productions are compared with the real value of industrial valves production.

Optimalizace najetí kontinuální chemické výroby
Svátek, Michal ; Kuncová, Martina (advisor) ; Heřman, Jan (referee)
Práce se zabývá optimalizací najíždění kontinuální chemické výroby, jenž má značný vliv na ekonomiku procesu. Základním pilířem práce je myšlenka optimalizace této komplexní operace na základě historických dat bez nutnosti užití složitých chemicko inženýrských výpočtů. V práci je využito moderních metod řízení ke zmapování procesu a následně k vyhledání míst, ve kterých dochází k největším prodlevám. Druhá část práce se zabývá optimalizací procesu s využitím modelů a metod řízení projektů, zejména síťové analýzy. V závěru práce je proces simulován pomocí metody Monte Carlo.
