    摘要:

    产品需求的不确定性使得企业经常产生临时性或突发性的物流需求,物流服务现货市场采购在应对上述物流需求时发挥了重要的作用。在物流服务采购决策过程中,由于长期合同采购所提供的价格折扣受采购量的影响,因此对托运企业而言,如何平衡长期合同采购以及现货市场采购,从而在满足其物流需求的基础上使得总体采购成本最低,成为一个需要解决的问题。本文基于托运人的角度,建立以最小化运输服务采购成本及最大化整体满意度为目标,综合考虑承托双方偏好、承运方总量折扣及承运方运力接受范围等因素的运输服务混合采购决策模型,并设计了多目标粒子群算法对上述模型进行求解。为验证本文所提模型及算法有效性进行了算例分析,算例结果表明,采用本文所建立的模型可显著降低运输服务总采购成本并有效提升整体的满意度水平。因此,本文研究成果对降低运输服务采购成本、促进承托双方的稳定合作具有一定的理论意义。

    Abstract:

    The uncertainty of product demand makes enterprises often have temporary or sudden logistics demands. The logistics services spot market plays an important role in responding to those logistics demands. In the logistics service purchasing process, because the price discount provided by long-term procurement contract are affected by the purchase quantity, so for the shipping enterprise, how to balance the long-term procurement contract and spot market procurement to achieve minimum overall procurement cost on the basis of meet the logistics demand, is a problem needed to solve. Based on the viewpoint of the shipper, this paper set up a transport services hybrid procurement model which took the minimum transportation service procurement cost and maximum the overall satisfaction as the objectives considering the factors including carrier and shipper preference, carrier’s total discount, carrier’s capacity acceptance range. Then we designed a multi-objective particle swarm optimization (PSO) algorithm to solve the proposed model. In order to verify the effectiveness of the model and algorithm proposed in this paper, an example analysis is carried out, and the results show that the model established in this paper can significantly reduce the total procurement cost of transportation services and effectively improve the overall satisfaction level. Therefore, the research results of this paper have a certain theoretical significance on reducing the cost of transportation service procurement and promoting the stable cooperation between the carrier and shipper.
