A MODEL OF THE PROCESS OF FUNCTIONING OF A MULTICHANNEL MEASURING SYSTEM OF GROUND-BASED TECHNOLOGICAL EQUIPMENT WITH LIMITED INFORMATION ABOUT ITS RELIABILITY

Background. The use of a multi-channel measuring system (MS) for ground-based technological equipment for its intended purpose involves the implementation of measurement procedures, the execution and (or) control of measurements of the parameters of space-purpose rocket systems and onboard equipment of spacecraft at the technical and launch complexes, with the evaluation of their values and the required accuracy. Therefore, the IS is classified as a measuring instrument. Materials and methods. The article develops a model of the process of functioning of the measuring channel (MC) of a multichannel measuring system with limited information about its reliability, which makes it possible to provide justification for the parameters of the metrological service strategy, in particular, the interval between verifications with a guaranteed availability factor, and comprehensively take into account the impact on the reliability of the MS of the main parameters on which it depends. Results and conclusions. It is determined that the use of this model using the apparatus of continuous linear programming at the design stage of the MC MS is one of the promising directions for substantiating the interval between the MC MS checks and calculating the efficiency indicator of the MS.
