Background. The relevance of the topic of work is due to the uneven distribution of the flow of applications to verification bodies without taking into account their structural and functional parameters. The aim of the work is to develop a model for the functioning of a distributed system of calibration bodies, which takes into account the number and types of jobs in each calibration body, traffic routes and the procedure for servicing applications.
Results. The approach to building a model of the functioning of a geographically distributed system of calibration bodies based on the use of the mathematical apparatus of locally balanced closed heterogeneous queuing networks is considered. A description of the model and the basic design relationships for determining the load and probability-time characteristics of the calibration processes of measuring instruments and the functioning of calibration bodies are given on the example of service models in a single-level distributed system of calibration bodies.
Conclusion. Using the model will allow us to determine the main indicators of the quality of verification work, taking into account both the composition and characteristics of the measuring instruments to be verified, and the structure and features of the functioning of calibration bodies. The considered model can be used to solve optimization problems in organizing and planning verification and certification work in a distributed system of calibration bodies.
