【摘要】 基于冷链物流配送车辆节能减排的必要性，在考虑固定成本、运输成本、时间窗惩罚成本以及制冷成本的基础上增加碳排放成本，建立了以配送总成本最小为目标函数的冷链物流配送模型，提出了一种解决该问题的改进蚁群算法，并使用算例验证了模型和算法。实验结果表明，该模型和算法有效，可以为物流企业的配送决策提供参考。更多还原

【Abstract】 Based on the necessity of cold chain logistics distribution vehicle energy conservation and emissions reduction,considering the fixed costs, transportation costs, time window penalty cost and cooling costs increase the cost of carbon emissions, on the basis of the established the minimum total distribution cost as the objective function of cold-chain logistics distribution model, this paper puts forward a solution to the problem of the improved ant colony algorithm, and using the example of the model and algorithm are verified. The experimental results show that the model and algorithm are effective and can provide a reference for the distribution decision of logistics enterprises.更多还原
