The paper deals with the relations between a priori identifiability and other structural properties and with identifiability conditions for compartmental systems.

Abstract
The paper deals with the relations between a priori identifiability and other structural properties and with identifiability conditions for compartmental systems. Reference is made to the notions of fixed structure system and of structural property. Structural controllability and observability and input and output connectability of compartmental systems are defined, and their relation discussed. Formal definitions are given for structural identifiability and unique structural identifiability. A newly formulated set of conditions for structural identifiability of compartmental systems is given that can be tested in an easy way directly on the compartmental diagram. Some observations reported in recent literature are discussed. © 1979.
