Mathematical model for crane scheduling in mixed yard
2018
In mixed yards, the stacking status of the container is not in the order of the shipment, causing the efficiency of the process of loading and unloading decreased. Therefore, it is very important to come up with a method using the existing facilities to improve the efficiency and reduce the cost.

We propose a method that sets a buffer in the yard to minimize the duration of the shifting process. To implement this method, the integer programming model is founded and the small scale accurate solution is used to implement the crane scheduling in the shifting process. The results showed that the model mentioned earlier can solve the problem of crane scheduling in the process of shifting with efficiency and provide strategic support for the management of yard.
