Complex production-quality evaluation by means of sample-identification methods

Abstract

pamong measured attributes and objects, which requires their simultaneous multidimensional analysis for the purpose of obtaining a substantiated evaluation of their combined informational value. 3. The incommensurability of certain marginal indexes which are measured in different units (rubles, volts, seconds, etc.) and, which is even worse, in different scales (ratios, orders, nominal units, etc.). Their normalization consists of a separate and complex procedure of selecting a certain "adequate topology" in the space under consideration of the object's initial description [2]. 4. The multiplicity of local criteria which characterize the object's separate aspects and are often contradictory. In this connection the tasks of optimizing and evaluating the quality of the product as a whole should be treated as a problem of vector optimization [3]; otherwise paradoxical solutions would most probably be obtained [2]. 5. The presence of uncontrolled disturbances which are often very considerable in all the stages of theobject's designing, manufacturing, functioning, and investigation (documentation errors, "technological noise," measurement errors, etc.).
