    摘要:

    针对生鲜商品物流配送优化研究在对客户需求时间窗和生鲜商品温度控制合理结合方面存在的不足,考虑生鲜商品存在配送时效性强的特征,构建生鲜商品配送的物流成本和生鲜商品价值损失最小的双目标优化模型.首先,建立包含生鲜配送车辆的运输成本、温控成本、违反时间窗的惩罚成本的物流成本模型,并建立基于温度控制的生鲜价值损失模型;然后,根据模型特点设计考虑客户空间位置、需求商品温度控制和时间窗约束的改进K-means聚类算法,进而提出一种GA-TS混合算法,该算法结合遗传算法(GA)的全局搜索能力和禁忌搜索算法(TS)的局部搜索能力,通过与HGA算法、MO-PSO算法和IACO算法的对比分析,对模型及算法的有效性进行验证;最后,通过敏感度分析得到最佳生鲜商品配送温度和最佳聚类方案数,研究结果表明模型和算法是合理有效的,可为物流企业的生鲜商品配送优化提供参考和决策支持.

    Abstract:

    In order to overcome the short comings of the fresh good logistics distribution optimization study in the reasonable combination of customers’ demand time windows and fresh good temperature control, and considering the characteristics of high timeliness of fresh goods, this paper establishes a bi-objective optimization model including the minimum logistics cost of fresh good distribution and the minimum loss of fresh goods value. Firstly, the logistics cost model containing transportation cost, temperature control cost and penalty cost of the time window is established, and the fresh value loss model based on temperature control is established. Then, according to the characteristics of the model, the K-means clustering algorithm is designed to consider the customer space location, the demand commodity temperature control and the time window constraint, therefore a genetic algorithm-tabu search(GA-TS) hybrid algorithm is proposed. This hybrid algorithm combines the global search capability of GA and the local search capability of TS. Through the comparison with the hybrid genetic algorithm, the multi-objective particle swarm optimization algorithm and the improved ant colony optimization algorithm, the validity of the model and the algorithm is verified. Finally, the best distribution temperatures of the fresh good and the best number of clustering schemes are obtained through sensitivity analysis. The results show that the model and the algorithm are reasonable and effective, which can provide reference and decision support for the logistics enterprise's fresh good distribution optimization.
