Application of Fuzzy Analytic Network Process and TOPSIS Method for Material Supplier Selection

摘要

Materials selection justifies a large proportion of engineering and construction project budget. Therefore, selecting an appropriate material supplier is a critical economic decision, and it plays a significant role in the success of engineering and construction firms. Traditional supplier evaluating decision-making methods are usually based on subjective opinions of experts, resulting in irrational and inappropriate decisions. This paper proposes a quantitative model for material supplier selection by using the Group Fuzzy Analytic Network Process (GFANP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) methods. The material suppliers are ranked by using the TOPSIS method. The proposed decision-making model can provide a robust approach for solving material supplier selection problems.
