The paper presents a production process optimization by the simulation approach. The research was realized by a case study for an enterprise producing welding pliers for the automotive industry. The solution of the study was realized in the environment of the Tecnomatix Plant Simulation software, which can simulate the production process after choosing the right conditions and connections among the elements. The research aimed at creating a simulation model of the evaluated process with real data and designing optimization solution of the production process, which assumes an increase in the devices and machines utilization. The results showed improvements in the efficiency of the production process, in the particular case increasing by more than 25%.

Abstract. For the efficient operation of each production process, individual machines and equipment must be used in the maximal possible measure. For this reason, it is necessary to know their utilization and to take measures to ensure their effective use. For performing such an analysis and to design subsequent measures, the use of the computer simulation method is very effective, e.g. simulation in Tecnomatix Plant Simulation program.
