Journal ArticleDOI
TL;DR: Any “state” description of timed nets must take into account the distribution of tokens in places as well as in (firing) transitions, and the state space of timednets can be quite different from the space of reachable markings.

Journal ArticleDOI
TL;DR: The structural properties and temporal specifications of GSPN are summarized, and application examples are illustrated, trying to emphasize the methodology to be followed in the model development and validation, rather than the numerical results that can be obtained from the specific models developed in the paper.

TL;DR: It is shown that a recovery block with independent tests can reach a higher level of reliability, and the coverage factor of the acceptance test is identified as the most critical parameter affecting reliability.

Journal ArticleDOI
TL;DR: In this paper, a policy of periodic replacement with minimal repair at failure is considered for the multi-unit system which have the specific multivariate distribution, where an operating system is completely replaced whenever it reaches age T (T > 0) at a cost c 0 while minimal repair is performed at any intervening component failures.
