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.

Manufacturing control algorithms for Industry 4.0 demonstrator
Klement, Petr ; Sýkora, Tomáš (referee) ; Kaczmarczyk, Václav (advisor)
The master thesis deals with the topic of Industry 4.0 demonstrator called Barman. The theoretical part is devoted first to what Industry 4.0 is, then to cyber-physical systems. The next element is an introduction to the status and functionality of Barman. The practical part is devoted to the commissioning of an Industry 4.0 testbed called Barman, which is a school model of an autonomous beverage mixing line, and the implementation of a virtual production mode in the different parts of the cells located in Barman. The next goal is to integrate with the existing Manufacturing Execution System (MES) that houses the individual drink recipes and their properties. The correctness of the integration of the MES system with Barman is also tested in the practical part not only in the virtual bridge. For the full functionality of the device, some hardware and software parts need to be tuned both on the Barman and in the MES system.

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.

Implementation of the DEECo component framework for embedded systems
Matěna, Vladimír ; Bureš, Tomáš (advisor) ; Bednárek, David (referee)
Recent development in the field of distributed and decentralized cyber-physical systems led to emerge of DEECo model. As many DEECo use cases are embedded applications it is interesting to evaluate DEECo on embedded hardware. Currently there is only reference DEECo implementation which is written in Java thus cannot be used for embedded applications. As part of this thesis C++ DEECo mapping and embedded CDEECo++ framework were designed using FreeRTOS operating system for task scheduling and synchronization. An example application designed for the STM32F4 board demonstrates usability of the framework. This thesis contains description of the DEECo mapping into the C++ language, source codes of the CDEECo++ framework, documentation and example application including basic measurement of its real- time properties.
