Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Information Model of Quality Assessment and Testing Control of Objects of a Complex Technical System A.V. POLTAVSKY, G.N. AKHOBADZE A campaign is proposed to solve the problem of optimizing the costs of testing objects of complex technical systems (STS). The main indicators of the effi ciency of the functioning of the units included in the STS during their testing are given. For the initial assessment of the technological and economic costs of testing, the use of a mobile algorithm and software tools that enable step-by-step technological solutions for quality assessment and test control is based. As an indicator of the effectiveness of testing samples and objects in the STS, a characteristic parameter is used that takes into account the main risks for the supplier and customer of products. An assessment of the quality of tests and costs is given, taking into account the tasks performed in a computer environment. Keywords: deviation, test object, statistical solution, error probability, risk, hypothesis, criteria. DOI: 10.25791/pribor.12.2023.1463 Pp. 39-43.
