Optimization of internal material flow
Kovář, Miroslav ; Veverka, Petr (referee) ; Simeonov, Simeon (advisor)
This thesis refers about the optimalization of internal business logistics system. This thesis want to explore and propose new solutions to the system of internal transport of material in a manufacturing company. The aim is find a suitable methodology for the problem and aplication this methodology to the particular case. The practical part describes the specific case of the production system in the Bosch Diesel s.r.o. at his plant in Jihlava. Description includes an overview of the current state of the logistical arrangements and problems that a rise from the current state. Compares the current state with the proposed state and investigates the various pros and cons. Part of the analysis is a computer simulation of the transport system, which has been support to confirming the appropriateness of the proposed solutions.

Design and simulation of manufacturing systems using simulation software for advanced planning and scheduling
Konečný, Štěpán ; Simeonov, Simeon (referee) ; Hromková, Ivana (advisor)
The Bachelor’s thesis deals with problematics of discrete-event simulation of production systems and clarification of basic concepts related to simulation, system, model and modelling using software for creating simulation models. The aim is to create simulation model of production line for paper boxes and to find the optimal solution that would meet the requirements for increase in productivity, eliminating downtime for individual machines while maintaining minimum production costs. The creation of the production system is solved in the simulation software Tecnomatix Plant Simulation 14. Furthermore, several solutions were designed and evaluated, from which the optimal solution with the lowest costs was selected.

Link robots
Szabari, Mikuláš ; Kotek, Luboš (referee) ; Simeonov, Simeon (advisor)
The bachelor thesis deals with the configuration of the link robots. It is divided into three parts. The first part interprets the robots, their division and ranked link robots into this division. The second part addresses the issue of the single cell structure and configuration of the whole robot. It also addresses workspace,location of endpoint and create a model. The third section discusses control systems, actuators and sensors.

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.

Vítek, Filip ; Kubela, Tomáš (referee) ; Simeonov, Simeon (advisor)
This master thesis is focused on Modular Self-Reconfigurable Robotic Systems. Their description is made at first and then possibilities of their use are listed. The next chapter concerns Molecubes modular system. The design of similar system where the construction of the individual modules is described follows. The transformations of coordinated systems in the individual modules are described and the calculation of forward kinematics and simulation of inverse kinematics is made at the end of the thesis.

APS system application for planning and scheduling
Zápotočný, Václav ; Hromková, Ivana (referee) ; Simeonov, Simeon (advisor)
Master's thesis, made at the Institute of Production Machines, Systems and Robotics, aims, evaluate existing production of slope mowers manufactured by Dvořák – svahové sekačky s.r.o., and then perform data collection for obtaining complete technological processes of production. With the APS (Advanced Planning and Scheduling) system, simulate and design an optimized solution, with a view to significantly reduce the required storage current inventory of manufactured parts for assembly of that slope mower.
