The Construction Of Hebei Netcom Decision Analysis System PHS User Run Off Forecast Subsystem

With the broken of the monopolized pattern, the competition among the domestic telecommunication operators is becoming more and more severity, however the simple price competition causes the loss of both sides of the competition. HeBei NETCOME urgently need to improve the ability of making scientific decisions, to strengthen the ability of making correct judgments in such aspects as market management. At present HeBei NETCOM have been built the Business Operation Support System (BOSS), accumulated magnanimity and electronic data, but each information system specialized in specific fields. These systems are different in data formats and way of visiting, so they become numerous information detached islands. It is redundant and inconsistent that the data exist in each information detached island, can't respond to the ability of making correct judgments.Decision Analysis System appeared in this situation. According to the construction of data warehouse on enterprise layer, the system can gather different customer data of on-line affairs processing system, also offer a data environment to a correct, intact and single view. At the same time the system must be able to also integrate the instrument of data analysis, front-end representation tools, offer the convenience that the policymaker can use and carry on performance analysis systematically.The author participated in the communication project management for a long time. And the author made a profundity comprehension on the PHS User Run Off Forecast System and the way to use it at the real work. Firstly, this thesis introduces the background of the research topic, the current situation and the organization of the whole content. Secondly, illustrates the related theories and technologies applied in the development of the system, such as datawarehouse, OLAP, ETL. Thirdly, the thesis analyzes the collectivity framework of the BASS. On the premise of understanding the collectivity framework of BASS, fourthly makes an example of how to design and carry out the PHS User Run Off Forecast System which includes definition, index, processes and result. At last, the thesis summarizes the whole content and makes an expectation on the development of the system in the future.
