description: This work is devoted to the development of a molecular vacuum pump model to analyze the influence of geometrical and dynamic parameters on the pumping characteristics. The objectives of the research were: 1) Study of different types of vacuum pumps, their design and use features; 2) Application of a multi-criteria ranking tool to determine the importance of various parameters and characteristics of a vacuum pump affecting its design criteria; 3) Creation of an ultrahigh vacuum simulator to study and optimize various parameters of vacuum systems, with the ability to analyze the model for stability, controllability, observability and simulation of time-dependent degassing processes; 4) Investigation of influence of dynamic and geometrical parameters of pumps on pumping characteristics. Mathematical modeling calculations with Matlab and Python software for pumping different substances were carried out, clearly showing the influence of geometry and dynamics on the main parameters inside the molecular vacuum pump. With this information model, the user can directly obtain the system pressure and use it in the study of the pumping characteristics of molecular vacuum pumps used in the design of pumping and pressure sensing mechanisms.
