—An approach for software flexibility measurement and measurement indexes based on BP neural network were proposed. By using the self-organizing, self-learning and self-adapting properties of BP neural networks, the rule of software flexibility measurement indexes weight concealed in the training data could be learned by means of BP neural networks… (More)
An algorithm of rule generation from incomplete information system is put forward in the paper. After some unknown values are predicted, extensive rules are generated and confidence factor is used to measure the validity of the uncertain rules.
this paper presents a new method which ensures the validity and availability of the essential services in SCADA systems using the real-time monitor and the simulation monitor. The real-time monitor is responsible for monitoring the states and critical control commands of systems, estimating whether there are faults and risk in systems based on security… (More)
