Due to a large competition and quick technological development competitiveness among companies on the market is increased. Companies can ensure their existence on the market with the production of quality products in foreseen times and for a competitive price. They can achieve this only with an optimized production process. Companies also try to reduce energy usage due to legislation pressures and increasing prices of energy products. Companies try to reduce costs and to stay in accordance with legislation, therefore, they are purchasing machines with higher energetic efficiency on which they carry the production. They are also looking into methods for minimizing the costs of product production.
One of the manners to reduce the operating costs, enable higher quality products, improve working conditions, and optimize the consumption of energy sources is to use lean production principles
In this master's thesis it is described more in detail two wider approaches of lean production; TPM (Total Productive Maintenance) and Six Sigma.
In the master’s thesis it islso defined some concepts that those approaches apply to achieve the objectives, e.g. Kanban, 5S, and Poka-Yoke. The use of these tools is presented in the master's part on the practical example of optimizing the use of heat energy in a selected company, where the analysis of losses and the practical use of lean production tools are also presented in greater detail. We can conclude that the tools of the individual methodology are intertwined and can also be adapted according to the company's findings and needs.
