FUNCTION-TARGET ANALYSIS AS THE METHOD OF PROPERTIES AND FUNCTIONS STRUCTURING OF METALWARE

Abstract

The paper is devoted to the analysis of one of the main concepts of quality metering – item properties. The authors give the classification of item properties, as well as, provide the possibility to describe the property structure of the estimated object from the point of view of the definition of the functions of different levels. The analysis of the properties of hardware items have been carried out. On the basis of this analysis it has been offered to define the notion «function». The notion «item consuming phase» has been introduced on the basis of functional analysis concept of item properties. It has been offered to introduce the constructive definition of hardware quality as a degree of item performance – a transport one, as well as, assembly and service ones. The system of analysis methods of hardware quality on the basis of the item function research over a period of its consumer phase is the essence of functional analysis. On the basis of this approach the algorithm of complex quantitative quality assessment has been approved. The developed approach differs with the concretization of the life-cycle stage, multilevel structure of the researched functions, as well as, the examination of one material body as the system of properties, revealed themselves in different ways, in dependence on target status condition. It allows positioning the function-target analysis as the original method of studying function and property structures of metalware.
