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

Design of inter-operational transport in a manufacturing company according to the Industry 4.0 concept
Mravec, Roman ; Vyroubal, Petr (referee) ; Bayer, Robert (advisor)
Based on the description and definition of technology and processes falling within the vision of the fourth industrial revolution with the aim of creating intelligent factories, this diploma thesis deals with the principles of the Industry 4.0 concept in Hilti's production plant with a focus on transport and supply of production equipment. The aim of the work is to create a comprehensive proposal that takes into account all the necessary aspects associated with upgrading the existing state of inter-operational transport in a particular production line to fully automated, flexible and autonomous transport of materials and products in the context of Industry 4.0. A prerequisite for creating a design is the connection of automatically guided vehicles (AGVs) serving individual transport orders. The selection of the vehicle was made taking into account the safety of movement, the method of charging, the system and network integrity of existing and proposed technologies and components. The intention is not only to automate the inter-operational service, but also on the basis of the created automation concept, the ability to autonomously procure the flow of material and products. The mathematical calculation of capacity planning in the production line helped to determine the total load and the number of vehicles needed for continuous procurement of transport requirements. The result of the design part is also the design of specific transport routes and transport conditions that AGV vehicles must comply with in order to maintain a high level of safety. Transparency and a constant overview of transported products is provided by the presented scheme for identification of production batches, Auto-ID system. The financial efficiency of the whole project elaborated in the diploma thesis is evaluated as payable after 4 years from the implementation of the proposal. The financial efficiency of the whole project elaborated in the diploma thesis is evaluated as payable after 4 years from the implementation of the proposal due to high labor costs.

Construction and production of 3D optical scanner
Běhůnek, David ; Zouhar, Jan (referee) ; Zemčík, Oskar (advisor)
The diploma thesis is focused on an optical method for 3D scanning. There is selected photogrammetry for creating 3D models. In the practical part, a mechanism for automatic photo capture is designed and manufactured and 3D printed with using a digital camera, Arduino microcontroller and stepper motors. There are proposed two methods of capturing photographs with which digital twins of reference objects are created. The result of the work is a functional 3D scanner. The next are evaluated used methods as well as the production costs and the time required by the operator when creating a digital copy of the object is listed.

Virtuální zprovoznění výměníku nástrojů CNC stroje
Rajdl, Filip ; Staněk, Václav (referee) ; Vetiška, Jan (advisor)
The Master’s thesis deals with virtual commissioning of the CNC machine tool changer. First deals with current state of knowledge with a systematic analysis of virtual commissioning. The 3D model is created by physical properties, sensors, actuators and control signals. In the last part of this thesis, a PLC program and visualization is created. The programs needed to create a virtual commissioning are jsou NX 12.0 - Mechatronic concept designer, SIMIT Simulation Platform V10.0 a TwinCAT 3.

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.

Creation of a Digital Twin and Its Control Based on the ANSI/ISA-S88 Standard
Holba, Jan ; Husák, Michal
This paper deals with development of detailed digitaltwin of small-volume liquid storage unit, as well as its completevirtual commissioning. The original design of the existing unit issubstantially modified to increase reliability and robustness. Thecontrol logic for PLC, according to ANSI/ISA-S88 standard, isalso created. Based on this implementation of the control logicfor the digital twin, its real counterpart will also be put intooperation.

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.
