Electric logistics vehicle scheduling method and system with time window

Abstract

The invention discloses an electric logistics vehicle scheduling method and an electric logistics vehicle scheduling system with a time window. The method comprises the steps of acquiring a distribution parameter of an electric logistics vehicle, and establishing a mixed-integer programming model according to the distribution parameter; acquiring a programming constraint parameter of the electriclogistics vehicle, and determining a programming constraint condition of the mixed-integer programming model according to the programming constraint parameter, wherein the programming constraint condition includes a programming requirement constraint condition and a charging constraint condition; performing optimal calculation on the mixed-integer programming model by use of an adaptive neighborhood search algorithm and a simulated annealing algorithm in combination with the programming requirement constraint condition and the charging constraint condition to obtain distribution path information; and completing optimization of electric logistics vehicle scheduling according to the distribution path information. According to the electric logistics vehicle scheduling method and the electriclogistics vehicle scheduling system with the time window, the distribution path of the electric logistics vehicle can be reasonably arranged to complete scheduling, the efficiency for a cargo distribution service is improved by virtue of the electric logistics vehicle, the electric energy is saved and the pollution to an environment is further reduced.

Description

Technical field [0001] The invention relates to the technical field of vehicle dispatching, and relates to a dispatching method and system for an electric logistics vehicle with a time window. Background technique [0002] In recent decades, the issue of green supply chain distribution has been the focus of attention of the whole society, and it is also the primary issue facing my country's energy conservation and emission reduction. Green supply chain management can not only significantly improve social benefits, but also an effective means to achieve economic benefits. The green supply chain can avoid waste of resources, enhance the company's sense of social responsibility, bring a good reputation and brand image of green products to the company, and help develop the product market. The supply chain is a circulation network composed of suppliers, manufacturers, retailers and distribution centers. Its purpose is to center on customer service. The most important part of the sup...

Problems solved by technology

At present, the algorithm for solving the scheduling of electric logistics vehicles with a time window is mainly based on the premise that once the electric logistics vehicles are charged at the charging station, the battery must be fully charged, which leads to the insufficient optimization of the scheduling results of the electric logistics vehicles, and the low efficiency in terms of power saving, resulting in electric The high transportation cost of logistics vehicles is not conducive to the development of logistics companies

When considering the location of the charging station and determining the specific amount of charging, the state space of the solution also expands rapidly, making the solution efficiency significantly reduced or even stagnant
