Optimization of the assembly process of rack stackers in a manufacturing company
Selzer, Tomáš ; Macíčková, Zdeňka (referee) ; Píška, Miroslav (advisor)
This diploma thesis discusses the matter of an innovative assembly process of rack stackers within a manufacturing company. This type of assembly is currently executed in a stationary manner, meaning that the individual parts and subassemblies are being assembled at several designated stationary workplaces. This results in a high number of worked-on units and a fluctuating rate of unit completion. Therefore, the main aim is to develop and establish a new assembly process concept, which will increase the production capacity, lower the number of work-in-progress units and improve the fluency of the assembly process. The thesis is divided into a theoretical and a practical part. The former part’s introduction serves to make one familiar with the chosen manufacturing firm and its products. Next, individual theoretical solutions followed by their applications for the firm are described. These are as a result of a thorough research conducted on scientific literature, mainly scientific articles. The second half of the thesis is concerned with an analysis of the current state of assembly process, where the key efficiency factors are identified, as well as with the process of designing an assembly line, using the One-Piece Flow concept, meaning the workers are only working on a single unit and the parts and subassemblies are moved between the operations. The concept design includes: a selection of suitable types of stackers, an estimation of an appropriate takt time, an analysis of the current assembly process, a determination of the time necessary for assembly and a design of three possible layout solutions, from which, based on multiple criteria, the most suitable one was chosen.

Value Stream Mapping and Optimisation
Gašpierik, Andrej ; Špinka, Jiří (referee) ; Novotný, Radovan (advisor)
The aim of this semestral thesis is to use the Value Stream Mapping (VSM) as visual aids to describe streamlining the production process of vibration welding machines in Emerson Industrial Automation, in Nove Mesto nad Vahom. In this thesis is contained description and comparison of the software support for the VSM. Theoretical part describes the causes of lean production and discusses the purpose of mapping of the value stream and variables associated with it.

Assembly Line Improvement Proposal
Zedníček, Antonín ; Kollár, Filip (referee) ; Bartošek, Vladimír (advisor)
The bachelor's thesis is focused on improving the process of a manufacturing company following customer orders. First, the theoretical starting points of improvement tools such as Lean Six Sigma are defined. Subsequently, the processed product and the company covering the production are introduced. Then, improvement tools are used to analyse the current state of the investigated process. The result is a proposal for a new solution, which is then evaluated, and the economic benefit is calculated.

Implementation of improvement methods of industrial production
NOVÁČEK, Tomáš
Nováček, T. Implementation of improvement methods in manufacturing. České Budějovice 2010. Bachelor thesis. Jihočeská univerzita v Českých Budějovicích. College of education. Department of physics. Supervisor Ing. Michal Šerý. This thesis describes a real application of improvement methods in manufacturing. The methods are applied to the obsolete line having the attributes of industrial production 80th of the last century. The main objective of the project is to build a new, robust manufacturing process to a logical flow with adequate capacity of produce. Next, process must be effective and with low risk of customer complaints manufactured products. On this occasion, it was necessary to apply modern methods to analyze the current state and the future state. During the construction of benches are accounted and described the principles of ergonomics in order to minimize the burden on the line for workers and prepare them to working conditions that they work effectively achieved without losses.
