Paper Title:
Determination of the Weights of Evaluation Indices with Combined Weighting Model for Engineering Materials
  Abstract

Combined Weighting Model (CWM), a new model combining entropy method, analytic hierarchy process (AHP) and back propagation network (BPN) is discussed to determine the weights(the key parameter of comprehensive evaluation) of evaluation indices(properties) for engineering materials in this paper. Taking the selection of bearing materials as an example, the combined weights of nine kinds of evaluation indices for ten kinds of candidate materials were calculated using CWM. According to these weights, candidate bearing materials were evaluated using Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). The result shows that the optimal bearing material is agreed with engineering application, which means the weights obtained from CWM are reasonable and reliable, and CWM is an effective method to determine the weights of evaluation indices for engineering materials.
