Abstract: A problem about the distribution amount of the alternate consumable between the vendors in chain store enterprises is researched.Considering the operation characteristics and the practical situation of the enterprise，this paper gives out the evaluation indicators and their measurement.According to the purchasing amount meeting the optimal summation of every indicator value，this paper establishes a multi-objective integer programming model and introduces its solution.Finally，a numerical example is given out to verify the validity of the model.
