可分离物品多属性多源采购的优化决策模型

以可分离物品的采购问题为实际背景,提出了可分离物品多属性多源采购的优化决策模型.首先在多属性信息下定义了采购商和供应商的效用函数;然后以社会福利最大化为目标,以市场出清价格为歧视性价格和统一价格两种不同形式分别构建了可分离物品多属性多源采购的供应商优选模型,通过求解模型得出最优的供应商和相应的供应量;最后,给出了一个电煤多属性多源采购的应用实例,表明了所设计的可分离物品采购决策方法的可行性和合理性.

Optimization decision models of multi-attribute and multi-source procurement for divisible goods

Optimization decision models of multi-attribute and multi-source procurement for divisible goods are presented
under the background of procuring the divisible goods. 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-attribute and multi-source procurement example about steam coal shows the feasibility and rationality of the
proposed model.
