Firstly, the buyer’s utility function and the supplier’s utility function are defined under the information of multi-attribute. Then, aiming at maximizing social welfare, two optimization models of selecting the suppliers in multi-source procurement of divisible goods are established based on the discriminatory price and uniform price respectively. By solving these models, the optimal suppliers and the optimal allocation strategies are obtained. Finally, a multi-attribu
