Abstract

The invention discloses an oil product secondary logistics distribution optimization method and system based on a variable neighborhood search algorithm. The method comprises the following steps: S1, obtaining distance information between an oil depot and each energy supply station, and driving time information required for transportation of distribution vehicles between the oil depot and each energy supply station; S2, acquiring oil depot information including the number of the distribution vehicles equipped in the oil depot, unit distance transportation cost, cabin capacity of each distribution vehicle and a transportation time window, and energy supply station information including unit time punishment cost of each energy supply station, oil product unit revenue, the demand quantity of each oil product order and delivery time of each oil product order; S3, establishing a distribution revenue maximizing model considering constraints of the transportation time window and the delivery time of the oil product orders; and S4, according to the distance information, the time information, the oil depot information and the energy supply station information, based on a variable neighborhood search algorithm, solving the distribution revenue maximizing model to obtain an optimal distribution scheme. The invention has the advantages that the constraints of the transportation time window and the delivery time are considered, and the distribution scheme is more reasonable.

Description

Technical field [0001] The present invention belongs to the field of finished oil distribution technology, and specifically, the secondary logistics distribution optimization method and system based on the variable neighborhood search algorithm. Background technique [0002] Finished oil secondary logistics distribution is a comprehensive process of comprehensive and complexity, which is affected by the binding and external factors of many aspects. Usually there are many transportation tasks, the number of bicycle delivery is small, the transportation equipment is small, the delivery frequency is high, the delivery plan is fast, the transportation requirements is strict, and the transportation cost is high. How to enhance the second logistics scheduling capacity of enterprises under the current resource conditions, improve efficiency, reduce costs, and increase profits, is a problem that enterprises urgently need to solve. [0003] Related research on refined oil distribution is ...
