Tecnomatix Plant Simulation is Siemens' object-oriented 3D simulation tool for modeling, visualizing, and analyzing production systems and logistics processes. It supports material-flow and resource-utilization studies across plant planning levels and imports CAD and JT data for realistic large-model visualization.

Production-engineering teams use it to validate manufacturing and logistics concepts before and during new-product introduction, with built-in bottleneck detection, throughput and utilization reporting, and experiment management through genetic-algorithm optimization. It connects to other Siemens tools such as NX Line Designer, Teamcenter, and Opcenter.
