THE ANALYSIS OF THE TECHNICAL SYSTEMS’ EVOLUTION

Abstract

Summary: The paper presents the results of the analysis of vibroprotective devices' evolution with use of Analytic Hierarchy Process (AHP). A series of perspective technical solutions created in different mo- ments of time was analyzed over the set of quality criteria being incorporated in the hierarchy. The mar- ginal analysis of criteria has revealed criteria and their groups, which are the most important for perfec- tion of pneumatic vibration isolators. The designing and the manufacturing of a competitive technical solutions need the analysis of develop- ment prospects for the devices being created. This problem is connected with the handling of large data- bases, where there is an information on devices of the considered class and close to it classes. The appli- cation of AHP for the information analysis enhances the creative labor efficiency at initial stages of de- signing. It is known from evolution theory, the information's value is determined by measure of its use. In this connection the software destined for the analysis of design databases enables to improve an informa- tion use and also gives an opportunity to discover a new knowledge. The analysis of technical systems (TS) with the same main function, which were created for a long period, enables to reveal criteria determining TS' evolution and its laws. The TS' evolution is considered as con- secutive transformations series represented by an evolutionary chain or an evolutionary tree. Each previ- ous technical solution is the prototype for an improvement at the next evolution stages. The certain stable changes of attributes (or criteria) during many generations of TS are named the laws of TS' development. The trends of functional, technological and economic properties of technical systems, if they are discov- ered, give to engineers a number of advantages in designing.
