Background. Verification of measuring instruments often involves the need for long-term removal from operating organizations. The decision in this situation is the formation of a exchange fund of measuring instruments in departmental metrological divisions. Thus, the relevance of the work is due to the need to justify the composition of such a exchange fund. In this regard, the authors of the work set themselves the goal of obtaining adequate calculation ratios that would make it possible to determine the volume of the exchange fund of measuring instruments, which ensures the normal functioning of the departmental metrological division.
Results. In work for assess the efficiency of the departmental metrological division a mathematical apparatus of a closed multi-channel queuing system with an unlimited queue is used. Based on complex performance indicators, the authors obtained ratios that allow determining the necessary amount of the exchange fund of measuring instruments of departmental metrological divisions.
Conclusion. The ratios obtained in the work make it possible to assess the feasibility of creating an exchange fund and calculate its volume. The adequacy of such estimates helps to reduce the redundancy of measuring instruments, and, as a result, reduces the cost of their purchase, operation, maintenance and disposal. On the other hand, the presence of a properly formed exchange fund increases the readiness of organizations solving target tasks, which is confirmed by the ratios obtained in the work.
