Embodiment Construction

[0014] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0015] In the present invention, a multi-type pre-cooling service resource scheduling optimization method in the first kilometer, the steps are as follows:

[0016] The first step, model building

[0017] The multi-type pre-cooling service resource scheduling optimization problem in the first mile can be expressed as follows: the pre-cooling service provider is responsible for providing pre-cooling services for fruit and vegetable farmers in a certain area, and several fixed pre-cooling stations have been established in this area. And equipped with a certain number of pre-cooling cars and light trucks. Each farmer has a certain amount of agricultural products, which need to be pre-cooled within the time period set by the farmer. Pre-cooling services can be divided into several types according to technical means (such as differential pressure p...

Abstract

The invention discloses a scheduling optimization method for multi-type pre-cooling service resources in the first kilometer, which considers two types of pre-cooling service resources, namely a fixedpre-cooling station and a pre-cooling vehicle at the same time, and constructs a double-target optimization model in a model part, namely minimizes the operation cost of a pre-cooling service provider, and improves the scheduling optimization efficiency of the pre-cooling service provider. The satisfaction degree of farmers to the pre-cooling service is maximized; in the solving part, firstly, amodel taking maximization of satisfaction as a target is solved based on an adaptive large neighborhood search algorithm, then the satisfaction target is converted into a constraint, the model takingminimization of cost as a target is solved, and a solution with the minimum operating cost of a pre-cooling service provider under certain satisfaction is obtained. An idea is provided for schedulingand optimizing fixed and mobile pre-cooling service resources in the first kilometer, and key decision support is provided for a pre-cooling service provider to efficiently carry out pre-cooling service.

Description

technical field [0001] The invention belongs to the technical field of logistics management, in particular to a scheduling optimization method for multi-type pre-cooling service resources in the first mile. Background technique [0002] The first mile in the field of logistics management refers to a series of operations such as pre-cooling, grading, processing, packaging, and warehousing of agricultural products from picking at the origin to logistics and transportation, so as to ensure the quality of agricultural products, reduce loss, and extend shelf life. Among them, pre-cooling is a key part. The so-called pre-cooling refers to the process of using certain equipment and technology to quickly remove the field heat of agricultural products and cool them down to a temperature suitable for transportation or storage. Therefore, it is necessary to improve the backbone network of the national agricultural product circulation, accelerate the construction of a public welfare ag...
