采购框架协议机制下的动态报童问题数据驱动建模研究

iming at the inventory problem under the framework agreement mechanism, a data-driven model is established to provide retailers with reasonable and effective decisions. Firstly, the deleted demand data was estimated by using the sales information recorded in the POS cash register, and then the multi-period dynamic newsboy model under the framework agreement constraint was established by using the sample mean approximation method. Finally, the effectiveness of the method was verified by numerical experiments. The research results show that the average total profit of the data-driven method is about 6%~18% higher than that of the traditional ordering strategy, and only about 3% lower than the average total profit under the theoretical optimal state. Through adjusting the relevant parameters, it is found that the average total profit of this method is the highest aResearch on date-driven modeling of dynamic Newsvendor problem under procurement framework agreement mechanismnd the change is more stable under various circumstances.
