Abstract. This study looks at selecting the partner in a logistics alliance as well as the intricate relationships between various factors. We use three research models herein. First, Interpretive Structural Modeling (ISM) establishes the criteria for the interrelationship structure, categorized according to their driving power and dependence. Second, because ISM does not provide any weighting associated with the criteria, we employ the Analytic Network Process (ANP) approach to calculate the weighted importance of the key factors and to identify those factors impacting the partner selection. Finally, TOPSIS method is used to obtain final ranking. To illustrate how the approach is used for the partner selection problem, an application of a real case in a company is conducted. The application has demonstrated the effectiveness and feasibility of the proposed model.
