Unifying DFT Semantics Sample Clauses
Unifying DFT Semantics. The interpretation of DFTs is subject to various subtleties, as surveyed in [4]. Varying interpretations have given rise to various DFT semantics in the lit- erature. The key aspects are summarised in Table 1. In the following, we focus on three key aspects—failure propagation, FDEP forwarding, and non- determinism—and show that these suffice to differentiate all five DFT semantics, see Fig. 11. Note that we consider the interleaving semantics of nets. Monolithic MA [13] Monolithic CTMC [11] IOIMC, Orig. GSPN Monolithic CTMC, Monolithic MA, New GSPN IOIMC, Orig.
