Abstract

The new approaches we have been looking at up to now are causing changes in the contents of traditional operative research and to the notions of relation and assignment, that of grouping in also added, which now acquires a new sense. This change is fundamental in order to arrive at profound renewal of traditional studies into the theory of decision.
