Applications of Decision Support System for plastic die materials selection were discussed in this paper. Decision Support System was established by combined entropy method with TOPSIS method, among which entropy method was used to determine the attribute weights of the candidate materials and TOPSIS method was used to sort the candidate materials.

In order to explore the relation between steel's dimple size and mechanical properties,it is necessary to measure and classify the dimple size accurately. An improved dimple image quantitative analysis method based on combination of wavelet transform and mathematics morphology was proposed in this paper. It measured and analyzed the dimples by means of edge(More)
An innovative approach based on partial least square is employed to predict thermal-fatigue property of hot-working steel. By extracting principal components, correlation information between properties of material and thermal-fatigue property under the operating temperature is screened and synthesized. Based on the research results, thermal-fatigue property(More)
