摘要:

即时配送物流形态随着外卖业的迅猛发展,配送时效和规模不断提高,使得配送骑手逆行、超速等违规现象激增。O2O外卖平台往往使用直线距离预估配送时间,但实际配送的城市商圈交通网络却具有非对称的结构,因此在该情形下的配送问题成为末端实时配送的重要研究问题。针对以上实际配送场景,提出非对称网络结构下的实时取送货路径优化问题。分析该问题的下界,针对需求点在特殊网络上设计JLNO算法,针对需求点在一般网络上设计JPI-rd算法和W&I算法,并进一步分析三个算法的竞争性能。使用数值仿真软件分析一般网络下的算法性能,发现非对称系数越大且配送网络结构越复杂时,JPI-rd算法更适用。结论可为O2O外卖平台的配送车辆提供不同场景下的合单配送策略和路径优化。

Abstract:

With the rapid development of takeaway industry, the time and scale of real-time distribution have been improved, which makes the traffic violations such as retrograde motion and overspeed increase sharply. The delivery time estimated through the straight-line distance by the platform, but the actual distribution network is asymmetric. Considering the above distribution situations, the real-time pick-up and delivery problem with the asymmetric network is proposed and analyzed with online algorithm. A competitive algorithm that matches the lower bound of the problem is designed, JLNO algorithm is presented for positive half-line metric space, JPI-rd algorithm and W&I algorithm are presented for general metric network, and the performance of three algorithms is further analyzed. A sensitivity analysis of various parameters indicates that the JPI-rd algorithm is more suitable when the asymmetry coefficient and the network are larger. The conclusion can provide delivery strategies and path optimization for delivery vehicles on O2O delivery platforms under different scenarios.
