In this degree are described basics of designing and planning of the production lines and cells, that are very dependent of the spatial distribution, number of workplaces and formed material flow. For the analysis of the chosen production cell and in continuation for the improvement of this cell, the program FlexSlim was used as help. Main goal of this degree was to find out, which solution of the cell would be the most appropriate one, regarding the minimal costs of production of the product unit. For the improvement of the chosen cell were given solutions, which are presented in chapter three. These were also taken into account by the improvement. Considering these solutions, the modernized simulation model of the cell was made and analyzed. The final part of this degree shows the results and findings of the improved production cell.
