基于缩短物流多阶响应周期的LRP模型研究

LRP Model for Shortening the Multi-stage Response Time of Logistics

建立了以缩短物流多阶响应周期和成本为优化目标的多目标设施定位—运输路线安排问题(LRP)模型。在模型的构建过程中,加入了对不同运输方式选择的变量,以满足用户对不同运输速度和成本的要求,并在成本计算中考虑了订货成本和分拣中心的固定成本。

To meet the customers' demands of fast response, shortening the multi-stage response time of logistics becomes the key factor to improve the level of logistics. Because the response time of transportation and storage is a large part of multi-stage response time of logistics, research of LRP accepts more and more attention in the world. In this paper, a multi-objective LRP model was built to optimize the multi-stage response time and cost of logistics. In this model the variable denoted the different style of transportation was added to meet the customers' demands of different transportation speed and cost. Cost for order and fixed charge of DC center was calculated in accounting the cost.
