Application of qualimetric methods for assessing quality of complex products

Abstract

For the final product high-quality assessment in any application field, it is necessary to choose the optimal method and suitable measuring instruments for the right conditions. The paper reflects theoretical information about the atomic emission spectrometer, the advantages of using this device in the quantitative chemical analysis when monitoring surface waters. In addition, information on methods for evaluating such complex products as the atomic emission spectrometer is provided. The paper presents expert and mixed methods of qualimetry, describes their advantages and disadvantages. Based on them, a new method for evaluating the quality of the atomic emission spectrometer has been developed, which includes elements of the expert method, differential and complex, as well as a method for determining the consistency of experts. In addition, the methodology sets out requirements for experts who are members of the expert group. It is designed such factors as: individual and group weighting factor, assessment of the consistency of experts with the help of the coefficient of concordance, relative indicator of quality, the product quality level, the weighted average arithmetic. Based on the assessment of the last indicator, you can conclude that this product is better or worse than the basic one, or rank several products. Three atomic emission spectrometers were selected for testing this technique. One of them was selected as the base sample, with which the two evaluated samples were compared. They were ranked from best to worst, and their example shows the efficiency of this method.
