UNCERTAINTY ANALYSIS,
Abstract
The total constraint of a dynamic system is analyzed in terms of the cause-effect relationship between parts of the system. The cause-effect relationships are represented qualitatively on Ashby diagrams of immediate effects (DIE) (Introduction to Cybernetics) and on diagrams of K effects for systems over k time intervals. (Construction of the DIE requires either knowledge of the mapping of every variable of the system and the mapping joining them, or the ability to force the system into all possible system states). Systems of 2, 3, and n variables are considered. Preliminarily, techniques are presented that facilitate analysis by allowing selection or creation of information relations of the desired form from a modest catalog of the most general and useful relations. Proofs are given for the reformulations.
