Abstract: Following appropriate strategic alliance stability literature reviews，a kind of stability evaluation index system of the logistic alliance which contains hierarchical structure is proposed，and then，utilizing the basic theory and method of rough sets，a logistic alliance stability decision-making model is established.In order to optimize attributes，the reduction algorithm based on discernable matrix is put forward.Finally，an example which is cited shows the method is effective and feasible.

摘要： 在对有关战略联盟稳定性的文献综述的基础上，提出具有层次结构的物流联盟稳定性评价指标体系。然后，利用粗糙集的基本理论和方法，建立基于粗糙集的物流联盟稳定性决策模型，并给出其中的基于分辨矩阵的指标属性约简算法，优化评价指标。最后通过实例说明该模型的有效性及实用性。
