ROCCO S, Claudio M  e  HERNANDEZ, Elvis. Non-parametric ranking in multi-indicator processes using HASSE diagrams and partially ordered sets: Enineering applicarions. Rev. Fac. Ing. UCV [online]. 2013, vol.28, n.2, pp.23-36. ISSN 0798-4065.

This paper presents the application of two non-parametric approaches allowing the ranking of processes characterized by a multi-indicator matrix: the Hasse diagram and the partial order set theory. Processes like the assessment of engineering projects, are described by a set of technical, financial, social and environmental attributes, among others. While parametric techniques try to determine an aggregate value for each process using subjective information, non-parametric approaches do not require additional information allowing an a priori analysis for: a) assessing if it is possible to define a unique natural ranking; b) determining if there are set of objects that could be partially ranked; or c) applying selected techniques for determine a ranking based only in the information provided by a multi-indicator matrix. The selected approaches are illustrated in three examples, related to engineering problems.
