Optimal layout proposal of technological workplaces and storage in a mechanical engineering company
Janderka, Pavel ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
The thesis presents a proposal of the arrangement of technological workplaces and warehouse in TIRAD s r.o. Analysis of the current situation revealed shortcomings in the current location of workplaces. Based on these findings and capacity calculations, two possible solutions have been developed. The first solution was to optimize existing production. The second solution, which was subsequently assessed as more appropriate, involves relocating production to a new production hall. This hall has a larger total production area where we can choose the machine layout to ensure the ideal material flow. Larger areas also guarantee the future development and expansion of the fleet. Thanks to a suitable layout, the transport distances have been reduced and thus the handling times have been reduced to less than half of the current state, resulting in both time and money savings.

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

Optimization of manufacturing process in a selected company
Koníček, Jan ; Císařová, Michaela (referee) ; Štroner, Marek (advisor)
Bachelor thesis is dealing with optimalization of manufacturing process in engineering company Kovokon Popovice s.r.o. First part is fucused on streamlining of material flow by using circular method and triangulation method simple, from which there are three variants of workplace layouts and the most advantageous one is selected. In the next phase of optimalization, a block diagram is compiled for original prodiction and subsequently for the modified one by using machining center replacing previous machines. Capacity calculations are then calculated for the block diagrams, which express percentage use of workplace and numbers of workers needed to produce selected component. In the last part of optimalization, the requied size of the central material werehouse, number of cranes and forklifts are calculated.

Logistic process optimization in expedition of electrical enterprise
Reboková, Lenka ; Jirák, Josef (referee) ; Špinka, Jiří (advisor)
Logistics as a process of planning, realization and controlling of effective and powerful workflow and commodities warehousing, services and related information with the goal of costumers satisfaction, became highly important and inseparable part of every company. The essential part of the planning process is an analysis of the current company situation, which tries to find all the limiting factors, and which serves as a basis for the process of making a company more effective. This diploma thesis analyses the current state of the expedition division of the ModusLink Czech Republic s.r.o. company – it analyses all its working operations in detail and using chronometrical analysis method evaluates division‘s theoretical and feasible throughput capacity. The feasible throughput capacity is then confronted with division’s real throughput capacity achieved during the monitored months, and depending on the results of the comparison there are some conclusions and recommendations for future improvements mentioned.

Proposal mechanical workshop in a small engineering company
Smrkal, David ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
Bachelor thesis deals with proposal mechanical workshop in a small engineering company. A disposition is proposed for component the gear. It must produce 150 000 pieces per year. The mechanical workshop is intended for serial production of gears, where design gear is supposed to be the most complicated product. On the basis of the literary study a problem of arrangement of workplaces and principle issues of designing mechanical workshop was designed a hall, which was situated in a subject arrangement. Machines are placed according to technological process. The width of hall was chosen a standardized value 18 m. By means of the capacity calculations were determined numbers of machines, workers and the place of the mechanical workshop.

Layout solution of a small workmanship within a given company
Urban, Antonín ; Peterková, Eva (referee) ; Štroner, Marek (advisor)
This thesis is focused on the process of making a disposition draft of a small machineshop producing 70000 bearing housings per year. Theoretical part of this thesis is focused on fundamentals of designing machining production units. Practical part describes in detail the process of designing dispositional solution for the machineshop which is based on performed capacity calculations. These calculations were used as a guide in the process of designing two diferent machineshops. The first one is fitted with conventional machining devices whereas the second machineshop uses CNC mills to produce the housing. These two projects are compared to each other to give reader a better picture on which machineshop of the two is better.

Technology project for non-rotary (plate) parts production
Henzl, David ; Horák, Jaroslav (referee) ; Rumíšek, Pavel (advisor)
The aim of the thesis is to elaborate the technological project for non-rotary (plate) parts production based on requirements of TOS KUŘIM – OS, a.s. The literary studies from the area of machining technology and technological designing are in the first part of the thesis. The evaluation of the contemporary state of production and dividing of products into groups is made in the next part. The following part of the thesis is dealing with the design and analysis of designed variants of disposition, choosing the most suitable variant, its optimalization and evaluation by the help of capacitive calculation. The drawing documentation (material flow included) and technoeconomic evaluation is elaborated in the final part of the thesis.

Production logistics of printed circuits desks
Susko, Petr ; Starý, Jiří (referee) ; Špinka, Jiří (advisor)
This thesis describes the design of a new plant for the production of printed circuit boards with a capacity of 40,000 square meters per year. Describes the basic principles of a new production, production logistics principles and technological design, procedure for application of the method SLP, placement of production areas and capacity calculation of employees and machines. It also describes the technological process of production of printed circuit boards with subtractive method and discusses the different steps of production with regard to the proposed production. The practical part deals with the actual realization of the project, a selection of production technology, machinery, design the layout of the building, capacity calculations, deployment tools, practical application of the method SLP, visualization of production in the Plavis VisTable software, waste management and economic evaluation of project costs.

Technological project at the engineering company
Smrkal, David ; Šenkýř, Jan (referee) ; Štroner, Marek (advisor)
The Master Thesis deals with technological project in the engineering company, that is named MAXAREN Ltd. The Thesis includes theoretical part about technological designing, analysis of the current status of the company, capacity calculations, layout and technical and economic assessment. The calculations are calculated based on the typical product of the company. The layout, that is designed in a technological arrangement, was made using capacity calculations and optimizations given by the company. It is clear from the technical a economic assessement that the investment is appropriate.
