“…During simulating the production process is evaluated the achieved output, respectively the operation of the production system during certain period, on the basis of statistical data [10,11]. The performance characteristics of the production systems can be summarized as follows [12][13][14][15][16][17]: utilization of resources, stock size in terms of the number of pending parts, machine failure statistics, machine blocking time, return on investment, cost indicators of production, the amount of scraps, the number of parts that were faulty, respectively require repair, trouble-free operation, time during which work is stopped due to device inactivity, waiting time of the product before workplace, monitoring of production performance, which indicates, how many products are produced during the simulation, continuous production time for a particular product, the amount of inventories and work in process of production.…”
