Abstract
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.
Highlights
With the development of modern port logistics, the logistics activities continue to be dense, the container transport become continuous popularization, and the growth of the throughput of ports, the problem of insufficient resources has begun to surface in the space of yards has become increasingly prominent
Management and scheduling of the cranes is of great importance
We are going to introduce the buffer area of the yards, take the minimum time to finish all requests as the goal, discuss and optimize the yard crane scheduling problem in mixed yard
Summary
With the development of modern port logistics, the logistics activities continue to be dense, the container transport become continuous popularization, and the growth of the throughput of ports, the problem of insufficient resources has begun to surface in the space of yards has become increasingly prominent To solve this very problem, the mixed model prevails, which means there are import and export containers in the same container terminal, at the same period of time. Due to the inconsistency of the container storage status and shipping sequence, the efficiency of the loading process This problem can be solved by taking the spare time before entering the yard to check the containers. We are going to introduce the buffer area of the yards, take the minimum time to finish all requests as the goal, discuss and optimize the yard crane scheduling problem in mixed yard
