The Mathematical Model Establishment Of The Duplicator Maintaining Information System With Statistics Resolution

The sample of this thesis is collected from a certain company's Duplicator Maintaining Information System. The maintaining records are from 1997 to 2001 year, and the data is almost discrete, multivariate and non-quantity. In the thesis I apply the professional statistic and analysis software on the base of traditional analysis method, withdraw related data, adopt a land of method to quantify the data, and establish corresponding mathematical model. At the same time, I do some detailed introduction about the regression method theoretically, and introduce a kind of thought which is to combine the linear regression method and Classification and Regression Tree (CART) method, in order to analysis the model hi quantity and quality. Finally, I proceed regression analysis with such two method in the S-PLUS, gain the analysis result from the Duplicator Maintaining Information System, and get the solution of the mathematics model.
