The Rsearch On The Application Of Data Mining In The Locomotive Quality Control System

With the gradually vigorous of market competition, the information is playing an increasingly important role in business enterprise survive and development. And it also requires higher governor to make effective decisions quickly and intelligently. It appeared three support decisions techniques in mid 90's lately: the data warehouse, on line analysis processing and data mining. The DSS (decision support system) integrated three of them which can complete transition from information to the knowledge.The main part of this thesis was token from the project named "the locomotive quality control and fix manage system of development and application", which is the Railway Ministry Science and Technology Program (serial number:2003 J036). The SQL Server 2000 was chosen as the development tool. Data Mining technique was introduced and basic principle of turn data excavation technique was presented. OLAP and the data warehouse, the SQL Server 2000 win decision tree were highlighted. Carrying on first step analysis to the data in the locomotive quality control system, the integration and conversion to several databases involved were carried on. The detailed design process and step of the data warehouse for decision making were provided. The bearings temperature diagnosis data warehouse serve as an example to show how to carry on a basic data to mining and mine description.The data mining technique in the application of the locomotive quality control is in its infancy, the DSS of the railroad locomotive quality control system has wide applied and development potential. The research work enunciation knowledge excavations used for the data analysis of the quality of the railroad locomotive is of great importance. It is greatly creative to introduct assistances decision the support work into the railway locomotive service segments. The further research that synthesize the information knowledge will set up the perfect analytical platform of the integrity, and carried out the leadership decision support of the higher layer establish solid foundation. The thesis made a beneficial probe into the application of these techniques in the railway locomotive service realm. The way of thinking enlightened the subsequent studies.
