Equipment Purchase Cost Model Prediction Based on Rough Set Main Factor Analysis
SUN Linkai
Abstract：Many factors influence the equipment purchase cost and each factor is not equally important .The factors in‐fluence each other .How to determine the main factor is the key to establish prediction model .The rough set reduction algo‐rithm is applied to pretreat the factors which influence the plane purchase cost ,and the support vector machine is used to build the prediction model .The example shows that the prediction model based on the main factors is superior to the model based on all factors .
