摘 要：文章針對冷鏈物流運(yùn)輸問題建立了優(yōu)化模型，使得冷鏈物流運(yùn)輸過程中的碳成本、時(shí)間窗的懲罰成本以及貨物的變質(zhì)成本總和最小，再運(yùn)用改進(jìn)蟻群算法，對其信息素濃度做出新的更新規(guī)則，避免了求解較慢和陷入局部最優(yōu)解的問題；文章最后應(yīng)用模型求解，得到最優(yōu)路徑和最低成本。

Abstract： This paper establishes an optimization model for the cold-chain logistics transportation problem to minimize the total cost of carbon cost， penalty cost of time window and deterioration cost of goods in the cold-chain logistics transportation process， and then uses the improved ant colony algorithm to make a new update rule for its pheromone concentration， avoiding the problem of slow solution and falling into local optimal solution. Finally， the model is applied to obtain the optimal path and the lowest cost.

Key words： cold chain logistics; optimization model; time window; improved ant colony algorithm
