Abstract: Second-hand electric materials refer to those used electric devices with problems made by irresistible causes, which can be saleable, restorable and usable. Management of second-hand electric materials is a key task in power companies. This paper, aiming at boosting used electric materials management and appropriately using used materials, studies the issues existing in the management of used electric materials in power companies,and presents value evaluation of used electric materials based on featured pricing model which overcomes the errors of traditional methods without considering the price changes of new materials.Linear function is used to calculate the price of electric materials with which featured pricing model is established. Principal component analysis is employed to quantitatively evaluate the values of second-hand electric materials. Flowchart is designed; factors and pricing history are also used to establish a regression forecast model.All factors are placed in a temporal order, which are used to evaluate the value of used electric materials based on featured pricing model. To validate this model, a simulating test is designed to compare with a traditional method. Results show an accuracy of about 95%, obviously higher than the traditional way, and fast speed, always less than 3 minutes, 1 minute at minimum, suggesting this method is effective.
