Abstract
This paper considers relationships between structural identifiability of compartmental systems and the interconnections of their compartments. First, structural identifiability is defined in such a way that the definition is practically significant and in addition, the interconnection structure of a system well is represented. Then an algebraic condition equivalent to this definition is derived. Based on this, necessary conditions are derived for classes of compartmental systems to be structurally identifiable in terms of interconnection graphs of compartments. A numerical procedure for examining the structural identifiability is given. The results of the application of this procedure to 3‐ and 4‐compartment systems show that the necessary conditions are also sufficient conditions. Finally, several conjectures based on the results of numerical computations are given.
