RENATO PENNACCHI · International Journal of Systems Science · 1972

The theory loads to a specification of several terms often used in this field, such as ‘ model ’, ‘ continuous or discrete system ’, ‘ discrete model of a continuous system ’, etc. Also some properties of the systems are specified, under extremely general conditions.
