An analysis of differential equations for systems involving bottlenecks
Borkovec, Ondřej ; Opluštil, Zdeněk (referee) ; Kisela, Tomáš (advisor)
This thesis deals with modelling of the flow of products through systems involving bottlenecks using ordinary differential equations. The model is based on hydrodynamics analogy. Further, the conditions for the sustainability of a system, that is the requirements needed not to exceed the maximal capacity, so that the flow of products can flow continuously through the given spot. A model is used to solve examples for vayrying systems.

Differential equations for systems involving bottlenecks
Šimečková, Kateřina ; Horníček, Jan (referee) ; Kisela, Tomáš (advisor)
The thesis deals with an analysis of differential equations for systems involving bottlenecks. The employed mathematical model originates from a hydrodynamical analogy. Further, the notion of sustainability, i.e. a situation when queues in bottlenecks do not exceed allowed limits, is discussed. In particular, conditions and algorithms enabling to describe sustainability properties of a given system are provided. The results are illustrated on several examples.

Application of Lean Production Methods on the Workplace
Kosařová, Zuzana ; Petržela, Jakub (referee) ; Juřica, Pavel (advisor)
The diploma thesis is focused on proposal of workplace modification according to the lean manufacturing methodology (DMAIC). The target is to minimize the wasting and to increase the production efficiency based on LEAN tools implementation. The theoretical part of the thesis defines the basic terms, such as primarily lean production, DMAIC, wasting. In the practical part there is at problem analysis using the DMAIC method, then the proposal for improvement is solved, that contains reduction of wasting, process of the project, timetable, costs and implantation of the solution, finally there is evaluated the benefit.

Simulation of different methods of transportation of a shaft on a lathe
Drábek, Vojtěch ; Simeonov, Simeon (referee) ; Hromková, Ivana (advisor)
This thesis focuses on computer simulation of manufacturing processes. In the first part, which is in the form of a research, the problem of simulation of real production processes, its applicability and possible limiting factors are discussed. In the second part of the thesis, the simulation of the operation of a specific production workplace focused on shaft manufacturing is practically processes and subsequently evaluated in the Tecnomatix Plant Simulation environment. The work simulates three variants of workplace layout - past, present and considered for the future.

Vylepšení procesu digitální podpory použitím osvědčených postupů přístupem ITIL, Kanban a TOC v multikulturním prostředí
Králik, Miroslav ; Bruckner, Tomáš (advisor) ; Kalantar Hormozi, Kaveh (referee)
Many companies today have to deal with business processes optimization, ongoing removal of system obstacles and identifying any bottlenecks laying on the way which are preventing us to reach our goals. I would like to show how we have dealt with similar problems in our case applied in the department of web application maintenance. In the first chapter I will introduce the basic information about the history, environment the company operate in and maintenance activities which are part of the process. Following with description all of the system obstacles and bottlenecks identified in the process and possible solutions or improvements for their elimination. In the last chapter I will present the achieved results after my executing of the proposed improvements and if the expectations have been met or not and what positive or negative influence it has brought.
