Quasi-ensembles d'ordre r et approximations de répartitions ordonnées

摘要

From a mathematical viewpoint, the theory of r-ordered repartitions deals with some extension of the concept of "power set", by the mean of a complete distributive lattice. As to interpretaiton, one may consider each r-repartition as the exhaustive distribution of some character (or quality) to all the elements of some set ü, according to r viewpoints, the viewpoints forming a chain (linearly ordered set). This paper deals uniquely with the establishing of some distance d on the set pr(ü) of all the r-repartitions of ü, and also of the approximation of any given r-ordered partition P by the subsets of ü which are the nearest from P, according to the metric d. Any of these subsets may then be considered as convenient for replacing P, and one may interpret this replacement as the result of some terminal decision.
