Popis:	Identifiability is a fundamental prerequisite for model identification. Differential algebra tools have been applied to study identifiability of dynamic systems described by nonlinear polynomial equations. In a previous paper a differential algebra method for testing identifiability for locally and globally non accessible systems has been proposed. In this paper we describe a strategy to simplify the above differential algebra method to test identifiability of systems which are non accessible from everywhere. In particular we make the method more efficient and thus of more general applicability. A strategy for testing identifiability also of nonlinear models described by non polynomial equations is proposed.
