In cold chain logistics, there is a certain opposing principle between pursuing low distribution costs, high freshness, and low carbon emissions. In view of this situation, three objectives are built in the routing model, including minimizing comprehensive logistics cost, minimizing carbon emission, and maximizing freshness of goods. Among these, comprehensive logistics cost is created by fixed cost, transportation cost, penalty cost, and so on. A comprehensive carbon emission model is used to describe and quantify carbon emissions. The freshness of goods is expressed by the punctuality. The more punctual the freight is, the higher the freshness will be. In this paper, the multi-objective function is transformed into a single objective function by weighting method, and a small-scale example is calculated by optimization solver. The effectiveness and practicability of the model are demonstrated by an example.
