    Knowledge gained from the Digital factory field needs to be expanded and further disseminated. The use of the Digital factory concept is mainly in laboratory conditions. It is essential for new knowledge to be made it more accessible for further experiments and for acquiring new knowledge for faster and easier deployment. The visualization of machines, devices, and entire manufacturing systems allows for almost faultless design of such systems. It is an expense saving and time-efficient solution. The article represents an experiment aimed at exploring simulation methods used in design and development of production systems by use of simulation digital tool. Comparison of the results obtained by examining the simulation model and real model will be made for acquisition of deviation between virtual model and real model. The task of optimization is, in this case, to create an optimal timetable for individual production lines by increasing flexibility and lowering costs, with prediction that the conditions are met and all orders will be made on time, minimize downtime, reduce production of waste and consider the efficient use of electricity.

    One of the factors that influence the production and assembly systems based on robotic cooperation is the reachability of the required locations as well as the design of the robotic arm paths without the need for initial testing at a real workplace, which could lead to damage of some parts in the workplace. The resulting robot paths must be collision-free, they cannot correlate with other elements of the automated workplace, they should also follow the set production cycle. The trajectory time described by the industrial robot end effector influences the overall production cycle time. For this reason, it is necessary to create a trajectory which represents the shortest path described by the industrial robot. The design of the end effector path of an industrial robot must in general meet many criteria, either in terms of tact or safety. By simulating multiple path trajectory variants in the digital environment, it is possible to select the ideal trajectory of motion of the industrial robot depending on the layout of individual elements of the production or assembly system and the elimination of collisions. When designing a robotic workstation, the main parameters of the industrial robot are range and load capacity. By implementing CAD data and customer requirements into the digital environment of the selected software, we can verify the data and choose the most appropriate solution. The main benefits of industrial robot application and the use of available software to efficiently design a robotic system include benefits such as shorter production times and associated higher productivity, labor cost savings and wage costs reduction, robots are used in other applications after the end of the production cycle of the original product, thereby achieving savings in investment costs.
