The advantages of simulation models are presented. A computer simulation model of an automated warehouse is considered and a solution to the model optimization problem of warehouse management is given. The model is implemented in the AnyLogic system using multi-agent modeling tools. These models can be used for clustering.

The article is devoted to the application of the Unity environment for geometric modeling of train traffic in existing directions in accordance with a given route according to a known schedule. The routes of the Moscow railway junction are considered as an object of modeling. The obtained results are supposed to be used to study the capacity of railway sections and optimize the schedules of rolling stock.
