Title: Evidence Theory Representations for Loss of Assured Safety in Weak Link/Strong Link Systems.

Abstract

The following topics are considered in this presentation: (i) Overview of evidence theory, (ii) Representation of loss of assured safety (LOAS) with evidence theory for a 1 SL, 1 WL system, (iii) Description of 2 SLs and 1 WL used for illustration, (iv) Plausibility and belief for LOAS and associated sampling-based verification calculations for a 2 SL, 1 WL system, (iv) Plausibility and belief for margins associated with LOAS for a 2 SL, 1 WL system, (v) Plausibility and belief for LOAS for a 2 SL, 2 WL system, (vi) Incorporation of evidence spaces for link temperature curves into LOAS calculations, (vii) Plausibility and belief for LOAS for WL/SL systems with SL subsystems, and (viii) Sampling-based procedures for the estimation of plausibility and belief. 2
