Abstract

Due to the limitation of later stage intelligent algorithms, the fruit and vegetable fresh-keeping cold chain transportation scheme did not meet the expectation and could not achieve the dual objectives of the shortest time and the lowest consumption at the same time. In order to solve the above problems, a cold chain transportation model of fruit and vegetable fresh-keeping in a low-temperature cold storage environment is proposed. The model is based on the topology of the cold chain transportation network. By setting the assumptions of the fruit and vegetable fresh-keeping cold chain transportation model, the objective model is composed of three parts: vehicle power fuel consumption cost, cold chain transportation refrigeration cost, and total fruit and vegetable loss cost. Under six constraints, the improved ant colony algorithm is used to find the optimal fruit and vegetable fresh-keeping cold chain transportation route. The experimental results show that compared with the methods based on ALNS, genetic algorithm, and quantum bacterial foraging optimization algorithm, the research method can bring the best comprehensive benefit by accomplishing the fruit and vegetable transportation task in the shortest time at the lowest cost, and the research goal is thus achieved.

Highlights

Fruit and vegetable consumption takes up a large part of our daily consumption
As the most frequently used fruit and vegetable transportation method nowadays, refers to the transportation of food at a preset low temperature to guarantee the freshness of food during transportation to reduce food loss
A low-temperature environment is maintained through vast energy consumption, which means that cold chain transportation consumes a large amount of energy. us, the delivery cost is greatly raised [2]

Summary

Introduction

Fruit and vegetable consumption takes up a large part of our daily consumption. Different from other types of food, fruits and vegetables have very short shelf life because of high water content and vulnerability, and they go rotten, especially in a high-temperature environment such as summer. As the most frequently used fruit and vegetable transportation method nowadays, refers to the transportation of food at a preset low temperature to guarantee the freshness of food during transportation to reduce food loss. Targeting minimum carbon emission cost and comprehensive cost, this method introduced the carbon tax mechanism; conducted quantitative analysis; adopted constraints of quantity demanded, time demanded, and discharge time; calculated the optimal solution of the distribution model using quantum bacterial foraging algorithm; and obtained the shortest distribution route [6]. Erefore, a cold chain transportation model of fruit and vegetable fresh-keeping in a low-temperature cold storage environment is built in combination with previous research experiences in allusion to the problems mentioned above. E model is expected to provide a reliable basis for cold chain transportation planning
