ABSTRACT: Cold-chain demand of fresh agricultural products is
increasing in China, while network layout of cold-chain logistics is in disorder and its
cost is huge. To address this problem, this paper casts an optimal model of
cold-chain logistics network and tackles it with genetic algorithms. This
optimal model takes running total cost of
logistics network as the objective, and embeds a nonlinear mixed integer programming including two assignment issues.
The model determines optimal layout and logistics management for pre-cooling
stations and logistics center for fresh agricultural products. Our main
contribution is to consider construction cost and operation cost of cold chain
logistics simultaneously. Case study illustrates the effectiveness of the
model.
