Assessment of workplace production line
Bařinka, Martin ; Knoflíček, Radek (referee) ; Tůma, Zdeněk (advisor)
The aim of this bachelor thesis is to evaluate the current state of knowledge in the design of production lines and assessing the selected production line. The theoretical part of the thesis is focused on the characteristic of production as a key proces in the company and the description of how to construct the design of the production system, the familiarisation with the essence and selected tools of lean manufacturing and ergonomics as a discipline occupied with adaptation of working conditions to a person’s performance capabilities. The practical part of the thesis includes a description of the assembly line for the production of lamellar grates at AHORN CZ, s.r.o, and an engonomic analysis of the workplace of the production line which also includes measures proposed on the basis of the findings followed up by evaluation and recommendations for practise.

Design of a method for measuring the leanness level of production processes
Medonos, Michal ; Blecha, Petr (referee) ; Čambál, Miloš (referee) ; Lenort, Radim (referee) ; Jurová, Marie (advisor)
Focus of this dissertation thesis is to find suitable methodology for measuring the leanness of the production process. The history of approaches to the optimization of production systems is outlined in the literature search. Furthermore, the methodology of lean production is described, the concept of leanness of the production process is defined and also the current approaches and methods of measuring the leanness of the production process are summarized. The next section presents developed Lead Time Leanness Indicator as a proposal for a suitable way to measure the leanness of the production process. Within the primary research, the necessary data are obtained from production companies using a questionnaire survey to test the usability of this indicator in practice. Based on the evaluation of the results of this survey, all established hypotheses are confirmed, and it can be stated that the defined indicator and its methodology is a suitable tool for measuring the leanness of the production process. It is further confirmed that this indicator can be used to set goals for the implementation of the lean production methodology also for a mutual evaluation and comparison of the efficiency of production processes of different companies. Another benefit obtained from the questionnaire survey is the mapping of the current state of the level of leanness of production processes and the intensity of the use of lean production tools in production companies not only in the Czech Republic but also abroad. At the end of the work, a case study is presented, which demonstrates the use of the indicator to determine the current state of leanness of the production process and to define any potential for improvement in a particular manufacturing company.

Lean Management of Production System
Medek, David ; Romanová, Eliška (referee) ; Bartošek, Vladimír (advisor)
This diploma thesis deals with lean management of production system in Inventec (Czech), s.r.o company, Brno branch of which produces desktop PCs and servers of Fujitsu brand. Management of production system is analyzed via tools and methods of lean philosophy and based on the information gained. Proposition (improvement) for a selected part of production system will be made, which will lead to elimination of wasting of resources and time.

Methods of Work Standardization as a Basis for Management of Production Processes
Vávrová, Monika ; Tesař, Rostislav (referee) ; Jurová, Marie (advisor)
In this diploma thesis, standards and norms for calculating time consumption in the company JULI Motorenwerk s.r.o., in Moravany near Brno, are developed. The aim of this work was to find out the state of current standards in the company and, if necessary, update them or create a new form for work standardization. The theoretical part describes the methods that can be used, either by direct or indirect measurement, for work standardization. The work also includes the development and introduction of the company. In the practical part, a proposal is created for work standardization using the selected method. Furthermore, individual tables are created both with the measured times and with the names and descriptions of the given operations, for clear standardization. The conclusion is an evaluation of the choice of methods for measuring standards and the creation of norms and the subsequent comparison of the resulting times with the times set in advance by the standards in the company.

Study of the Introduction of Lean Manufacturing Based on Cooperation with Supply Chains
Karpov, Daniel ; Tesař, Rostislav (referee) ; Jurová, Marie (advisor)
The diploma thesis deals with the improvement of production processes according to the principles of lean production. It is divided into three parts, theoretical, analytical and proposal. The theoretical part describes the methodologies and procedures by which processes can be analyzed and further improved. In the analytical part, the company Gebauer and Griller, s.r.o. is first introduced with its production system. This system is analyzed after that and its shortcomings are revealed. In the proposal part, there is the concept of making changes, the implementation of which will solve those shortcomings, and its economic evaluation.

Use of a simulation model for the development of an automatic algorithm for creating a routing table and path evaluation in a conveyor system
Weyrová, Dominika ; Simeonov, Simeon (referee) ; Hromková, Ivana (advisor)
The diploma thesis deals with the use of a simulation model for the development of an automatic algorithm for the creation of a routing table and route evaluation in a transport system. It includes a search of modeling and simulation issues and state-space search issues with an analysis of available search methods. The simulation model of the transport system is created in the software Tecnomatix Plant Simulation, where an algorithm for automatic creation of routing tables for routing and evaluation of routes according to static criteria is subsequently developed and tested. The work presents a proposal for the principle of the algorithm for evaluating the routes of the transport system, including dynamic criteria and their optimization.
