In the last years, the use of composite indicators has consistently increased, and the necessity to build model-based composite indicators with a strong
methodological statistical approach becomes more and more important for reasons
of trustworthiness. In this paper, we propose to build a composite indicators system
able to measure different levels of relations among (group of) variables according
to an ultrametric form which detects a hierarchical structure upon (group of) variables. Each dimension is measured as a specific composite indicator which reflects a
subset of variables. In order to show its potential and applicability, the methodology
is employed to analyze a dataset which contains variables about separated waste
collection in Italy taking into consideration both its performance and its costs
