A decision process operated by a system in correspondance with its observation of the set which includes its environment as well as itself.
R. VALLÉE, who introduced the concept, writes: “If we want to model the decisional process which follows the observation process (processes which are artificially separated for intellectual commodity but, in fact, are only one) we must go on from y, a function describing the evolution of perceptions, to function z describing the evolution of decisions or controls decided at each instant (in a way considered here as automatic for the sake of simplification) which must act upon the effectors: z = D(y) where D is a decision operator” (1990, p.40).
Considering that y represents what the system perceives through the observation operator (a “distorted and impoverished image” of the real situation and its evolution) we have thus z = D(O(x).
VALLÉE calls this product the pragmatic operator .
