| 目的 为了减少水产品在运输中因配送不及时造成的货架期损失，研究基于水产品剩余货架期损失成本的冷链路径优化问题。方法 引入货架期损失成本，建立基于水产品剩余货架期的冷链运输路径优化模型(VRP-SI模型)，根据冷链车的不同配送时间对货架期损失成本进行分段研究;优化目标为最小总配送成本，模型结合改进遗传算法和模拟退火算法求解，进一步采用Solomon算例进行仿真实验。结果 货架期损失成本VRP-SI模型比普通路径优化模型减少支出分别为14.28%、12.86%、15.58%，减少总体成本支出分别为8.41%、6.07%、5.25%。结论 VRP-SI模型能够达到降低配送总成本的效果，为水产品冷链路径优化问题提供有效的解决方案。 |

| The work aims to study the cold chain path optimization problem based on the remaining shelf life loss cost of aquatic products, so as to reduce the shelf life loss of aquatic products due to untimely delivery during transportation. The shelf life loss cost method was introduced and a cold chain transportation path optimization model (VRP-SI model) was established based on the remaining shelf life of aquatic products. The shelf life loss cost was studied in segments according to different delivery times of the cold chain vehicles. The optimization objective was to minimize the total delivery cost. The model was solved by combining an improved genetic algorithm and a simulated annealing algorithm, and further simulation experiments were conducted with Solomon examples. The results showed that the VRP-SI model reduced expenditures by 14.28%, 12.86%, and 15.58% respectively compared with the ordinary path optimization model, and reduced the overall cost by 8.41%, 6.07%, and 5.25% respectively. In conclusion, the VRP-SI model can reduce the total delivery cost and provide an effective solution for the cold chain path optimization problem of aquatic products. |
