# Development and Verification of a Simulation Model of an Automated Assembly Line
## 2 Application of Simulation Models
### Application of the Program on Selected Examples  
Tecnomatix Plant Simulation finds practical application in many areas of industry, but it is also often used in scientific studies. There are many research papers where the Plant Simulation program was used.  
An example of the use of Plant Simulation can be the analysis of the machining process described in the work of [PERSON], [PERSON] and [PERSON] [32] The shaft machining process consisted of cutting, centering, turning and grinding. After the first simulation, it was confirmed that turning is the bottleneck. Then, various configurations of the arrangement of machines responsible for turning operations were simulated in order to obtain the assumed efficiency of the process. Thanks to the simulation, it was possible to quickly find the right machine placement to achieve the assumed capacity, but at the same time, the first two operations had more than half of the unused capacity buffer. Simulation gives the opportunity to find areas of cost reduction, efficiency improvement and can help in risk analysis.  
[PERSON] et al. in their work presented the application of the Tecnomatix Plant Simulation system to build a simulation model of an intersection with traffic lights [33]. Such a simulation can help to better understand and analyze traffic, assess problems and propose the best solution for sustainable urban development. The program enables the creation of complex models, e.g., design and planning of industrial parks, where the simulation will help identify problems that could worsen the traffic situation in transport nodes. To sum up, Tecnomatix Plant Simulation allows for the creation of full-scale microscopic motion models. It is suitable for modeling and simulating traffic and allows the visualization of various road processes.  
Tecnomatix has also found its application in the expansion of production in the production plant [34]. The company has built a new room where production will be located. Using a simulation model, proposals for the arrangement of machines and workstations were prepared. The model can be modified many times, thanks to which various solutions for a new production are verified in a simple and effective way before starting the process. The program helped detect some problems that were not foreseen in the initial design. Thus, it can be concluded that simulation is a good tool at the stage of production planning.  
[PERSON], [PERSON] and [PERSON] in their work used Plant Simulation as a solution that can support the transition from manual to semi-automatic or automatic assembly [35]. At the very beginning, it was determined which assembly tasks were suitable for automation, and then a semi-automatic station was designed in the program. As a result of the simulation, the time at the semi-automatic station is 35% shorter than with manual assembly. Such a stand can still provide flexibility in production. Thanks to the simulation in the program, it was shown that semi-automatic assembly can be profitable for a company that wants to implement it.  
Tecnomatix Plant Simulation is software with a wide range of applications. The functions of the program enable the creation of complex simulation models, and the possibilities of the program are not limited only to the creation of models for production and logistics systems.
