Third-order optimazed design of Nanjing Olympics Game Center control network based on sensitivity investigation

The third-order optimazed design is mainly used to revise the old network,which aims at decreasing the field work under the precision and the reliability of the network.The weakest position is probed by sensitivity in this paper.The new concept of comprehensive sensitivity is put forward and compared with precision sensitivity and reliable sensitivity with examples.The conclusions are:the third-order optimazed design with reliable sensitivity is better than precision sensitivity;and comprehensive sensitivity is effective to find the weakest position of the network.
