Technique for order performance by similarity to ideal solution (TOPSIS) is one of the multi-attribute decision-making methods and is used to solve supplier selections and other questions generally. In the process of evaluation focusing on production, there are many evaluation objects and hierarchical structures among objects. Decision makers pay more attention to the classification of objects, namely:good, medium or poor, though the evaluation systems for above problem are very insufficient. Therefore, this paper proposes a new three-way decision evaluation system based on TOPSIS. First, the analytic hierarchy process(AHP) method is used to calculate the weight of attributes. Then, to solve the hierarchy relations among objects, a preliminary classification is added before the process of evaluation. Finally, the improved TOPSIS method is used to evaluate objects. Case analysis result shows that the proposed method is effective.
