Abstrakt: In this paper, the network reliability of an actual digital instrument and control system (DICS) network is analyzed by using GO-FLOW methodology (GFM). The evaluations of common-cause failure (CCF) and uncertainty are incorporated. Three significant CCF groups (real time servers, gateways, reactor protection system) and three typical time intervals (10 min, 1 h, and 24 h) are selected in the analysis. It is concluded that the network contribution of CCF accounts for over 68% of the system failure probability. The result indicates that GFM is suitable for the network reliability analysis.
