摘要：為了解決冷鏈物流服務的成本、質量以及運輸產生的碳排放等問題，構建多中心半開放式冷鏈物流路徑優化模型，并將各種動態變化融入該模型中。設計一種改進的NSGA-II算法并利用標準測試函數證實該算法具有較好的收斂性與多樣性。通過算例實驗，結果表明：與不考慮碳排放方案相比，考慮碳排放方案的配送成本增加了19.00% ，運輸距離減少了5.16%，碳排放成本降低了13.03%；與初始配送方案相比，實時優化方案的配送成本下降了29.78%，碳排放成本下降了23.19%，客戶滿意度增幅14.49%；與單配送中心模式相比，多配送中心模式的配送成本降低了27.30%，碳排放成本降低了48.89%，客戶滿意度提高了13.11%，從而為冷鏈物流企業帶來一定的管理啟示。

In order to solve this problem， a multi- depot half-open cold chain logistics routing optimization model is constructed， and various dynamic changes are integrated into the model. An improved NSGA-II algorithm is designed and the standard test function is used to prove that the algorithm has good convergence and diversity. The results show that， compared with the scheme without considering carbon emission， the distribution cost of the scheme with considering carbon emission increases by 19.00%， the transportation distance decreases by 5.16%， and the carbon emission cost decreases by 13.03%. Compared with the initial distribution scheme， the distribution cost of the real-time optimization scheme decreased by 29.78%， the carbon emission cost decreased by 23.19%， and the customer satisfaction increased by 14.49%. Compared with the single distribution center mode， the distribution cost of the multi-depot mode is reduced by 27.30%， the carbon emission cost is reduced by 48.89%， and the customer satisfaction is increased by 13.11%， which brings certain management enlightenment for cold chain logistics enterprises.Key words: cold chain logistics; multi-depot ; dynamic path optimization; improved NSGA-II algorithm
