This diploma thesis is based on creation of a simulation model of paint shop in the company ŠKODA AUTO a.s. The model was created in the simulation software Tecnomatix Plant Simulation. It is tested by simulation model whether the planned modifications in a buffer for sorting cars by their color would have positive effect on Perlenkette principle. The Perlenkette principle will help to stabilize supplier processes and reduction of running production times. Conclusions are deduced from carried out simulation experiments.
