Abstract
Problem Statement (Relevance). The relevance of the work is due to the need to increase the efficiency and objectivity of the ultrasonic testing process of metal products, especially in cases of further manufacturing of hazardous industrial facilities. The existing requirements and rejection criteria for ultrasonic testing can lead to the judgments subjectivity of the specialist who makes decisions about the suitability of metal products, which can cause either the omission of defects or unjustified product rejection, which dramatically reduces economic efficiency. Objectives. The study is aimed at developing a scientifically based approach for the formation of an effective and minimally sufficient set of rejection parameters in ultrasonic testing of metal products, ensuring a balance between its rigor and economic feasibility. Methods Applied. The paper involves the construction of a mathematical model describing the dynamics of consumer-manufacturer interaction and establishing a general level of control rigor based on an analysis of standards and the nature of defects. Hierarchy analysis and matrix transformation methods are used to transform subjective expert assessments into an objective, quantitatively substantiated system for weighing the significance of individual ultrasonic testing criteria. Originality. The paper describes the development and application of a comprehensive two-stage method that integrates mathematical modeling to justify the need for strict control and objective evaluation of criteria using matrix transformation and hierarchy analysis methods. This approach makes it possible to significantly minimize subjective factors, ensuring a high degree of reliability of the results obtained. Result. A methodology that allows a person making the decision on the suitability of metal products to move from an intuitive assignment of rejection parameters to a quantitatively justified system has been created. This method provides the formation of a resulting set of ranked criteria that guarantees maximum control efficiency while simultaneously eliminating redundant parameters. Practical Relevance. The implementation of the proposed approach will significantly improve the reliability, objectivity and economic efficiency of ultrasonic testing of metal products. The developed method opens up areas for further development, including its adaptation to other types of non-destructive testing and the creation of automated decision support systems for flaw detection specialists.
