APS system application for planning and scheduling
Zápotočný, Václav ; Hromková, Ivana (referee) ; Simeonov, Simeon (advisor)
Master's thesis, made at the Institute of Production Machines, Systems and Robotics, aims, evaluate existing production of slope mowers manufactured by Dvořák – svahové sekačky s.r.o., and then perform data collection for obtaining complete technological processes of production. With the APS (Advanced Planning and Scheduling) system, simulate and design an optimized solution, with a view to significantly reduce the required storage current inventory of manufactured parts for assembly of that slope mower.
Optimization in conveyer rollers production
Veverka, Štěpán ; Heinl, Zdeněk (referee) ; Rumíšek, Pavel (advisor)
Presented document deals with optimization in conveyer rollers production in accordance with rationalizing project for Transroll – CZ, s.r.o. company. With consideration of available literature from section of technological projection and technology of machining, the industrial process is analyzed with focus on material flow and layout solution of factory shop. Consecutively the options of possible machines allocation are designed, which eliminate some disadvantages of default position. Selection of suitable option, its evaluation and technical-economic evaluation of whole project are also parts in this document.
Value stream analysis and improvement
Malec, Tomáš ; Hégr, Ondřej (referee) ; Novotný, Radovan (advisor)
This thesis deals with the general analysis and value stream improvement. The theoretical part describes the difference between functional and procedural model of company management, mutual benefits and disadvantages of these systems. The thesis deals with the mapping process, subdivision maps and methodology of process maps creation. The work also includes software analysis for process mapping. Next section contains search of selected optimization tools and methods to improve production flow and description of the principles of controlled documentation. In the practical part is realized mapping process of bachelor studies at FEKT and map of production process at ABB switchgear.
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.
Optimalisierung einer Produtionslinie in einem bestimmten Betrieb
Drdová, Vendula Bc. ; Korcová, Marcela (advisor) ; Marianová, Eva (referee)
Práce se zabývá rozborem portfolia sortimentu podniku vzhledem k výrobnímu procesu, dále analýzou částí výrobního procesu a vyhledáním jeho problémových míst. Dále je řešena vybraná problémová oblast rozmístění výroby a zhodnocen návrh optimálního řešení.
