The notion of the signature is a basic concept and a powerful tool in the
analysis of networks and reliability systems of binary type. An appropriate
definition of this concept has recently been introduced for systems that have
ν possible states (with ν ≥ 3). In this paper we analyze
in detail several properties and the most relevant aspects of such a general
definition. For simplicity's sake, we focus our attention on the case
ν = 3. Our analysis will however provide a number of hints for
understanding the basic aspects of the general case.
