Simulation is one of the universal tools for studying complex technical systems. Simulation is used to solve optimization, prognostic, and logistics problems, as well as to design, develop, and debug digital twins and control systems. To solve such problems, the MTSS (manufacturing and transportation simulation system) simulation system has been developed. The MTSS system is a visually interactive process-oriented discrete simulation system implemented in Java in the Eclipse environment. The MTSS system provides the following capabilities: use of a graphical editor, visually interactive model construction, various methods for setting model parameters, various model execution modes, 2D, and 3D visualization of model execution, and statistical analysis of modelling results. MTSS implements the possibility of distributed simulation based on the HLA transport layer standard using the RTI implementation — Pitch pRTI. MTSS has been successfully used for over ten years to model a wide range of manufacturing and logistics systems. The article presents an overview of the most significant models developed using MTSS for various subject areas: an oil and gas production enterprise, a distributed data processing system, an ore crushing and transportation complex, and coal mine subsystems (conveyor subsystem, water pumping subsystem, power supply subsystem, and working face subsystem). The coalmine subsystem models developed for one of the Kuzbass coalmines.
