Weak and directional monotonicity of functions on Riesz spaces to fuse uncertain data
Sesma Sara, Mikel ; Mesiar, Radko; Bustince Sola, Humberto (Elsevier B.V., 2019)
Artículo / Artikulua
In the theory of aggregation, there is a trend towards the relaxation of the axiom of monotonicity and also towards the extension of the definition to other domains besides real numbers. In this work, we join both approaches ... -
The weak data on the water–energy nexus in Spain
Sesma Martín, Diego ; Rubio Varas, María del Mar (IWA Publishing, 2019)
