This diploma thesis is based on creation of a simulation model of the conveyor bridge between a paint-shop and an assembly hall in the company Škoda Auto, a.s. in Mladá Boleslav. The model was created in the simulation software Plant Simulation on the grounds of an existing model in simulation software SimPro. Analysis of the existing model in software SimPro as well as a system analysis of conveyors used in the respected production section is carried out in the thesis. Results of simulation experiments accomplished with the newly created model follow. These experiments verify the throughput rate for various production programmes. On the grounds of these results a bottleneck analysis of the conveyor system is carried out and arrangements leading to increase in its throughput rate are made.
