Research of unascertained assessment method in retailing reverse logistics risk factors

The reverse logistics is necessary for retailing to reinforce competitive advantage, increase customer value and improve its whole performance of supply chain. The retailing reverse logistic is either a premise of effective decision or important method for enterprise to decrease operating risk and improve service. In the paper, a new evaluation method is proposed by analyzing evaluation problem of retailing reverse logistics including the characteristics of uncertain information. Firstly, evaluation index system is established, and grading standards is put forward. Secondly, factor results and index weights are qualitatively described. Thirdly, the qualitative result is transformed to quantities value. Then unascertained number of factor result and index weights is established. Finally, using unascertained number algorithm, the result of evaluation is worked out. The method is verified by a case study.
