COMPARATIVE MULTIOBJECTIVE ANALYSIS OF COMPLICATED TECHNICAL AND SOCIAL SYSTEMS IN TERMS OF ECONOMICS AND MANAGEMENT

Abstract

The article is devoted to the comparative multiobjective analysis of complicated technical and social systems in terms of economics and management. The difficulty of carrying out such comparison is determined by multidimensionality of the target application, diversity and qualitative variety of separate system elements, dissimilarity of technological conditions, under which they are created, and analogues used for the comparison. It is not about choosing the one “best” solution out of several alternatives, how it is required having the traditional optimization task setting, but about the comparison of home object to its analogues. Usually the purpose of such comparison consists in the assessment of its comparative objective efficiency. However, the object compared is the product of the respective technological chain. The resources used to create the object and analogues compared are always different as well as technologies used to transform resources to end products. It is the reason for the new problem to assess the management quality of own object creation as compared to the analogues. Objectives. The purpose is the development of effective approaches to the management quality assessment of complicated technical and social systems creation. Four multiobjective tasks of integral assessment are considered to solve the stated problem: objective efficiency assessment, assessment of all kinds of resources used, applied technology assessment and finally three-objective task to assess the management quality of object creation with assessed objective efficiency by using stated resources and technologies. The last task implies achievement of the highest objective efficiency with the use of less resource and less sophisticated technology that points at the higher management level. The stated task pertains to the class of multiobjective decision making where alternatives are distinguished by partial criteria and depend on the range of uncertain factors. Methods. The methodology of solving this problem relies on the use of confident judgment method that allows making decision simply and on a reasonable basis taking into account only natural judgments. The stated method does not use artificial procedures, intended to formalize the task by means of searching the unique appropriate way to consider uncertainty, but takes into account the whole variety of such ways. Indeed the method allows identifying the rating of the required solution that represents the rate of uncertainty consideration ways whereby this solution is the best compared to other ones. Results. Test approval of the proposed method application are illustrated through the management quality comparative analysis while creation of Global Navigation Satellite Systems (GNSS). Russian Global Navigation Satellite System (GLONASS) is compared to similar systems of the USA (GPS), Europe (Galileo) and China (Kompas/Beidou). Conclusions and Relevance. The proposed approach has powerful capabilities and can be used in complex comparison to the existing analogues of complicated technical and social systems both being created and already in place. The method gives the possibility to acquire useful information about the quality and the efficiency of such systems and to elaborate recommendations regarding further development.
