The proposal of lean production implementation in a industrial enterprise
Nachtmann, Pavel ; Bartošek, Vladimír (referee) ; Jurová, Marie (advisor)
This master´s thesis describes the production process in Japanese enterprise Daikin Device Czech Republic s.r.o. with emphasis on the production schedule, equipment and manufacturing system with elements of lean production. According to the production process analysis at the given production line a new solution of the production process has been suggested to increase production efficiency. This conception has been implemented and compared to the production process before, as well as to the assumed production process after increasing the efficiency.

The Study of Inventory Management in Connection with Manufacturing Process
Tieber, Michael ; Klíma, Jan (referee) ; Jurová, Marie (advisor)
This master’s thesis deals with problems of inventory management in the International Repair Centre for Symbol Technologies Czech Republic s.r.o.. Actual inventory management is described with a focus on materials planning, storage and evidence of inventory movements using information database systems. A part of the thesis is also an analysis of inventory categories from several different aspects. The purpose of the master’s thesis is to submit suitable suggestions of how to improve existing inventory management processes.

APPROACH TO REDUCING LEAD TIME IN MANUFACTURING SYSTEMS
Hromková, Ivana ; Škopán, Miroslav (referee) ; Šťastný, Jiří (referee) ; Mostýn, Vladimír (referee) ; Knoflíček, Radek (advisor)
Presented PhD thesis aims at development of new methodologies and approaches to reduce lead times in production systems. Therefore the thesis examines in detail the design of new, more comprehensive approaches to shortening lead times. The dissertation describes the methodology of using these approaches in production systems, it is suggested their inclusion in the control structure of production and adequate managerial support for the successful application of these new approaches in the industry is developed. The first part summarizes current knowledge in the field of reducing lead times. The various methods that can be used for reducing lead times are defined and described, from which is selected discrete simulation of manufacturing systems as a suitable method for the purposes of issue development. The next part of this work is therefore devoted to simulation approach to reducing lead times and the factors that affect them, such as processing time, size of the batch, queue lengths, etc. In this part is also discussed the use of information technologies (programming languages, libraries, and software tools) that enable efficient creation of simulation models. The second part is focused on industrial applications implemented to reduce production lead times. Specific simulation analysis deal with, for example, reduction of the lead time for manufacture of surgical instruments, screws, slats, but also transport systems, optimization of production orders input to the production system, the issue of supply, etc. The second part also describes a practical approach to data transfer to / from the simulation model, simulation software connection to the ERP database of enterprise and energy intensity of production. The conclusion summarizes the findings that were detected on the issue of reducing lead times, and within the chosen methodology, simulation of manufacturing processes indicates possible further progress in the research and practical applications.

Proposal for the Production Process Improvement
Chvátal, Štěpán ; Bartošek, Vladimír (referee) ; Videcká, Zdeňka (advisor)
This thesis deals with the optimization of production processes in a small manufacturing company engaged in the production of pumps and the determination of a new cost structure and work performance. Altogether, there are five proposals for optimizing the manufacturing and warehousing processes in the company. I have used EPC diagrams to describe the processes. Then, I used a qualitative data collection method to determine the duration of each operation for almost all workers in the firm and a quantitative data collection method from the information system for all workers to determine the ratio of overhead operations to total work output time. A suggestion for optimizing the storage and retrieval process plus the lack of space for product storage is to purchase new storage racks and new lifting equipment for the company. To enable more detailed tracking of work performance, I have created a new labor reporting structure. I have created a new cost structure to sort the invoices received. As a result of my work, all the proposed measures have been successfully implemented in the company.
