Using of Discrete Event Simulation in a Production Planning
Shylin, Ivan ; Chadima, Libor (referee) ; Videcká, Zdeňka (advisor)
Diploma thesis is dealing with the possibility of use of discrete event simulations in a production planning. The connection of the work measurement and the production planning is described. The thesis describes the modeling methodology, design and realization of the experiment with the model. The production planning part describes the processing of the data generated from the model, which are further used to demonstrate the planning method and optimization of the production plan.

Optimization of Material Flow in Mass Production by Means of Simulation Methods
Hloska, Jiří ; Simeonov, Simeon (referee) ; Manlig, František (referee) ; Škopán, Miroslav (advisor)
The aim of the PhD thesis is to design a methodology for generating a material flow using a simulation meta-model of a mass production process. This methodology is in principle based on the relationship between selected material flow characteristics. Simulation of production and logistics processes has been increasingly used in planning, commissioning and subsequent operational management and optimization of the respective technological operations, in particular in mass production. The first part of the PhD thesis summarizes up-to-date findings in the field of discrete event simulation of material flow, related statistical and mathematical disciplines, but also information technology which enables effective realization of simulation studies. Attention is also paid to significant domestic and international conferences, symposia and interest associations related to simulation of manufacturing processes. The next part of the PhD thesis presents the methodology of reconstruction and generation of material flow using simulation meta-models developed for this purpose. Principles of algorithms used by these meta-models and their possible range of use are demonstrated by simulation experiments carried out. Their description and results are also commented. Special focus is put on the selection of significant material flow characteristics and their mutual relationship. For its evaluation a series of simulation experiments was conducted using a simulation model of a closed queuing system with variable parameters. Revealed interdependence between the selected material flow characteristics is experimentally verified using a detailed simulation model of particular selected mass production system. The conclusion of the PhD thesis summarizes provided findings and, with regard to the designed methodology of reconstruction and generating of material flow, it outlines possible further steps both in research and their practical application.

Computer simulation of an automated rack stacker
Chalupa, Pavel ; Juříček, Martin (referee) ; Hromková, Ivana (advisor)
The aim of this bachelor's thesis is to create a simulation model of the High Bay Storage using the simulation program Tecnomatix Plant Simulation. In the first part of this thesis, a software analysis was carried out, Plant Simulation was selected to process the problematics of discrete simulation of production systems. This is followed by an explanation of the terms model, simulation run and system. Additionally, discrete and continuous simulations are compared in this part of the thesis. This section also explains the problematics of High Bay Storage, including their automation options, stackers and storage stocks management. Palletization together with different types of automated storage and retrieval systems are discussed as well. The second part of this thesis contains a simulation model of the warehouse with multiple types of storage and retrieval systems. All these types are evaluated, and the most effective option is selected.

Bus Communication Visualization Toolkit
Mojzík, Michal ; Ježek, Pavel (advisor) ; Horký, Vojtěch (referee)
The typical way of teaching the basics of computer bus functionality is a presentation of an abstract timing diagram, that describes a number of various concepts simultaneously, which can be difficult to understand. Presenting a practical example of a bus communication, that student could interact with, is usually not feasible. There is a lot of virtual computer systems, that could be used for creating such practical example. Unfortunately, none of them allow the visualization of bus transmissions. In this thesis we alter the Bochs virtual computer in such a way, that its data transmissions are taken into an external application of our creation, that allows simulation of a bus transmission over a bus topology and presentation of such transmission to the user in a form of a timing diagram. The design is carried out with the expectation, that the program will be used as a learning tool. We also design the program to support various parallel buses, while adding the ISA bus as an example.
