A variable ordering heuristic for risk monitors based on zero-suppressed binary decision diagram
Fds Team · Chinese Journal of Nuclear Science and Engineering · 2010
The probabilistic safety assessment model using for determining the instantaneous risk in a risk monitor are much more complex than the operational model using for determining the average risk.Therefore the development of a fast calculation engine is indispensable and challengeable.the scale of zero-suppressed binary decision diagram.In this paper an optimized method of variables ordering,which fully utilized that features of operational model,was proposed.Not only the theoretical demonstration but also the applications were also brought out.
