This paper intends to propose some reference suggestions by analyzing the evacuation situation and the robustness of the evacuation network once a nuclear accident takes place, with the influential factors on the evacuation being observed. As is known, in the nuclear installations and facilities, great importance has to be paid to the road transportation and traffic perfection for the personnel evacuation system network on the basis of the actual evacuation network of nuclear facilities. Just from the said need, we have built up a nuclear facility evacuation Bayesian network as the Bayesian ne...
