Machačová, Simona ; Janírek, Martin Stanislav (referee) ; Videcká, Zdeňka (advisor)
This bachelor’s thesis deals with the analysis of the production process and its optimization. Improvement is achieved thanks to a predictive simulation. The theoretical part of the thesis describes the concepts associated with the process management of the company and measurement of work. Furthermore, the theoretical part focuses on the improvement of business processes within the process of digitalization and methodology of simulation projects associated with the creation of a predictive digital twin. The analytical part contains an introduction of the manufacturing company and a global analysis of processes. Then, with the help of several techniques, the production process which will be optimized is analyzed. The design part of the thesis describes the current simulation models and the proposed form of the process. Individual options are evaluated, and the benefits of the proposed solution are stated.

Predictive Simulation as a Tool for Decision Making Support
Horák, Michal ; Hruška, Tomáš (referee) ; Videcká, Zdeňka (advisor)
The bachelor's thesis focuses on analysis and optimization of the assembly line of gear pumps. The bachelor's thesis contains a suggestions for changes on this assembly line in order to balance the line and optimize utilization of operators on the line. The solution uses a dynamic simulation model that corresponds with the real state of the line. The simulation model is further used for experiments and selection of the ideal solution with respect to the selected objectives

Optimization of the production process in the sense of Industry 4.0
Sázavský, Jakub ; Březina, Michal (referee) ; Mauder, Tomáš (advisor)
Particularly the future of industry is and will be defined by the concept of Industry 4.0. Therefore, this thesis aims to describe the basic conceptions of Industry 4.0 in relation to the production process and demonstrate the possibilities of digital twin by using simplified model of a real production line. It explains terms such as the production process, the concept of Industry 4.0 and the queueing theory. The practical part includes a model of the section of a line in the printing company by the program Tecnomatix Plant Simulation, identification of bottlenecks, possibilities of optimization and evaluation of their impacts. Then there is an example from business practice and drawn conclusions.

Digital twin
Kopeček, Pavel ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This thesis deals with the issue related to digital twin technology, which is developing during the current 4th industrial revolution primarily based on digitization across industries and in the near future, if properly applied, can be one of the core elements of most industrial processes. A digital twin represents a virtual representation of a physical object (machines, functional components, for example, within cars or even a part of the human body), with which it transmits information to each other in the form of data important for the target functions of the digital twin through the created communication channel. With the use of the obtained data, the control algorithm of this technology and through simulation models contained in the virtual space of the digital twin, this technology enables real-time work, the purpose of which is to perform an analysis of the operational state for the purpose of its evaluation, correction or, using the so-called "what-if" analyses, even its prediction, with the aim of achieving the most efficient use of real objects during their entire life cycle (production process of the object, operation and maintenance of the object, disposal of the object). The main outputs of this work are, from a research point of view, the performance of a critical evaluation of the current state of the application of digital twins within the industrial world and the creation of a digital twin creation algorithm, from a practical point of view, the creation of selected input 3D analyzes (simulation models) and the creation of a reduced ROM model for the purpose of creating basic building blocks for a digital twin of two-stage train transmission. For the practical part the Ansys Workbench system package and a relatively new system for calculating dynamic tasks called Ansys Motion were used.

Digitization of teaching models
Dvořák, Tomáš ; Kaczmarczyk, Václav (referee) ; Sýkora, Tomáš (advisor)
This thesis focuses on the digitization of laboratory fixtures Case Sorters and Drills. These laboratory fixtures were assembled within the framework of bachelor theses from previous years for teaching at the Brno University of Technology. The thesis deals with the digital twin, one of the concepts of Industry 4.0. It is a technology that enables the digitization of physical reality for monitoring, simulation and prediction. It is a trend that is already used in many applications not only in industry. This work shows the conversion of laboratory preparations into digital form in order to simulate physical operation and subsequent testing on physical equipment. The models are controlled via the TIA Portal from Siemens in Ladder language.

Use of laser scanning in heritage buldings
Müller, Jan
In the case of heritage buildings (and not only in their case), the problem is often the absence or outdated drawing documentation. In recent years, instead of the traditional surveying of buildings with the help of onedimensional tools (whether we mean a tape measure or a laser rangefinder), three-dimensional surveying using laser scanning, in which a virtual spatial copy of the object is created with the help of millions of points, the so-called point cloud, has been slowly gaining ground. This cloud or clouds can be used to create 2D and 3D documentation of the existing state of the building with much greater speed, accuracy and clarity than conventional methods. Currently, the two most widely used methods of laser scanning using so-called LIDAR are the static method, using fixed stations, and the dynamic method, using modern technology in the form of precision IMUs. The paper describes the principle of these two methods, their advantages and disadvantages and also the way of working with point clouds created in this way. Unfortunately, the greater spread of virtual representations of real objects created in this way is hindered by the higher purchase price of the necessary instruments, but already today their cost is many times lower than in the recent past and in the foreseeable future they could hopefully be available to all who would need them in their activities. The article also includes examples of point clouds as well as examples of the outputs they have produced.

Methods for Design of Virtual Twin of a Dynamic System
Kšica, Filip ; Novotný, Tomáš (referee) ; Holub, Michal (referee) ; Hadaš, Zdeněk (advisor)
Over the last decade, digital twins and cyber-physical systems have been slowly developed from mere theoretical concepts to potent industrial applications in a large spectrum of areas, however, ambiguous understanding of the fundamentals significantly complicates the process of finding a general methodology necessary for their successful implementation. Therefore, one of the main goals of this thesis is a systematic study of these concepts and their main parts, followed by formulating a methodology that could lead to successful and effective industrial applications in the context of current projects. The key part in this effort falls to computational modelling and dynamic reduction of complex mechanical systems that comprise the digital part of a digital twin, including but not limited to the main structure but also sensing systems. These sensing systems serve as cyber-physical systems that fulfill the role of interactive links between the individual parts of a digital twin and are introduced in the last part of this thesis in the context of manufacturing industry, airspace, and railway industry, where they are used not only for condition and operational monitoring, but also provide large amount of accurate real-time data for structure health monitoring and predictive maintenance purposes.
