Sudėtingo reiškinio struktūrizuotos rodiklių sistemos formavimas

Abstract

When a phenomenon is getting complicated, acquiring more particular features or aspects, it is becoming more difficult to determine the relationships between the criteria describing it. In this case, it is hardly possible to determine the criteria weights based on expert evaluation. Moreover, the question arises if the statement that the criteria describing a complicated phenomenon are interrelated as the elements of a single system is true. A comprehensive analysis shows that only hierarchically structured system of criteria can adequately describe a complicated phenomenon (CP). This system accounts for the variation of the criteria relationships, when the number of parameters of the phenomenon is growing. The direct relationship can be observed only between the criteria of the same set describing a particular CP aspect, while indirect relationship can be found between the criteria describing various CP aspects. This implies that there is a connection characterized by direct relationship between the aggregated magnitudes pertaining to the criteria considered. The paper offers a method of structuring a system of CP criteria, allowing us to determine the significance of the criteria based on direct relationship between them.
