The Application Of Decision Support System (DSS) In The Maintenance Of Transmission Line

In the public communication network, optical fiber data transmission net is the basis of all the other data nets, value added nets and support nets. In order to ensure the safety and expedite of the transmission net, except reinforcing the maintenance and manage , it is necessary to adopt the new artifice and new tech equip, establish scientific and advanced maintenance system.In the open envirament, the optical cable line is liable to impact by the people or nature disaster, so as to break down and lead the transmission net lost function. The optical cable line is the weakness of the fiber data transmission net, it affects all the operations of the telecommunication net.In the local fiber data transmission net, in order to improve the qualityof line maintenance and reduce the period of trouble, it is important to accumulate the experience and grip the hidden trouble of all the line section. On the other hand, the important info should be subsistenced compactly. When there is trouble, using the info, the maintenance people can orientation the site rapidly. Therefor, combine the resource checking of local transmission net, it is reasonable of using the decision support system (DSS) to establish a model, which can be used to instruct the maintenance. It is a good discuss for local optical cable line maintenance, also, has a highly practical value.Decision support system (DSS) is a new type computer knowledge. It is a integration of all kinds data, info, knowlage and model tech. It is applied widely in industry, agriculture, transportation and other domains, shows important decision support ability.This thesis contain the follow contents:(1) Analyse the trouble from JAN 2005 to July 2006 of local optical cable net of SHENYANG UNICOM. From the analysis, it can be confirmed what info should be offered when these is a trouble.(2) Based on the ananysis of upwards, establish the model.(3) Bring forward the method of store DSS data in the Excel form. (4) Confirm the DSS man-machine interface.(5) Compile the software and simulate using.
