The Value Model of Customer Relationship Management Based on Rough Set and Fuzzy Theory

The paper gives a new value model based on rough set and fuzzy theory to value the companies' customer relationship management. Because the number of customer relationship management' indices is too many and the calculation is very complex, this paper uses rough set to play down the complication. Because of the subjective effect of value people, the fuzzy theory is used to improve the objectivity. In the last, the paper used the of eight telecom companies' data to test the model. The experimental results show that the new model has better precision and it proved that the new model is a better method.
