Abstract:
Structural circuits are considered whose units are described by the operators $A_i:X_iY_i$. Data on the structure is shown to be useful in solving the equation set $F_i(X_i,Y_i)=0$. The models of dynamic systems of causal operators are analyzed and crudeness is discussed. Solving the dynamic problems in terms of the operators $A_i$ which reflect the cause-and-effect relations of the variables and specifying the structure offers advantages over solution with the circuits represented as equation sets.
