Urban two-stage distribution and scheduling method with mobile distribution station

Abstract

The invention discloses an urban two-stage distribution and scheduling method with a mobile distribution station, aiming to improve the urban distribution efficiency. According to the two-stage distribution mode, goods are transferred to a distribution station located in an urban area from a distribution center located in a suburb through a truck, and then tail-end distribution is completed through the distribution station by means of a light-weight vehicle. Existing distribution stations are fixed in position while the requirements of urban customers are changed every day and the rent of an urban center is expensive, so that a distribution route is not optimal every day, and the cost is high. According to the urban two-stage distribution mode with the mobile distribution stations, trucksare used as the mobile distribution stations, and the positions of the mobile distribution stations dynamically change according to the requirements of customers every day, so that the distribution paths every day are optimal. For the distribution mode, a clustering-based variable neighborhood search scheduling algorithm is designed, and the clustering algorithm is used for determining the position of a mobile distribution station, and variable neighborhood search optimizes a distribution path, and a selection strategy in a non-dominated sorting genetic algorithm III is adopted to select a multi-target elite solution. Meanwhile, a truck direct distribution strategy is designed in the algorithm, so that the efficiency is further improved and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of logistics scheduling, and in particular relates to a two-level urban distribution and scheduling method with a mobile distribution station. Background technique [0002] The main purpose of urban distribution is to deliver goods in a city in an efficient manner, taking into account traffic congestion, safety and environmental factors. With the rapid increase of urban population, the acceleration of urbanization and the continuous improvement of customers' requirements for delivery timeliness, urban delivery is facing huge challenges. (Savelsbergh M, Woensel T V. CityLogistics: Challenges and Opportunities[J].Transportation Science, Vol.50, No.2, May 2016, pp.579–590) At present, the two-level distribution model is the most commonly used distribution model for urban distribution Ways, for example, JD.com, Cainiao, etc. Two-level distribution uses different types of transport vehicles at different levels.

Problems solved by technology

TNT Company conducted a three-month pilot project in Brussels, and the results showed that it has obvious effects on reducing urban traffic congestion and pollution emissions, but the cost input is relatively high, and a certain amount of space is required to place the transportation equipment (D .Merchan and E.E.
