Application of Distance Evaluation and its Improved Algorithms in Engineering Materials Selection

Abstract:

Distance evaluation and its improved algorithms using Vertical distance instead of Euclidean distance were discussed in engineering materials selection. Taking the selection of materials for low temperature storage container as an example, based on eight kinds of evaluation indices, according to the weight obtained by AHP method, ten kinds of candidate materials were evaluated by using distance evaluation and its improved algorithms. The results indicate that, the optimal material selected coincides with the practice of industry, and the sequence of the candidate materials arranged using improved algorithms is more reliable, which shows that improved algorithms of distance evaluation is a feasible and effective way for engineering materials selection.
