This application provides a container terminal scheduling method, system, and medium based on critical event reverse scheduling, relating to the field of intelligent terminal scheduling technology. The method decomposes loading and unloading instructions into event sequences containing multiple critical event nodes, and combines this with the dynamically generated expected arrival order of containers based on ship stowage, stability requirements, and hold limitations. This constructs a multi-dimensional event correlation relationship encompassing the internal timing of instructions, partial order dependencies between loading instructions, and the priority of loading and unloading operations. Based on this, starting from the completion time of the overall ship operation plan or the time node set for the optimization target, a reverse recursive algorithm is used to accurately calculate the latest expected arrival time for each non-occurring critical event, thereby generating real-time scheduling instructions with time constraints. This effectively avoids invalid queuing of trucks under gantry cranes and idle waiting of gantry cranes, significantly improving the collaborative efficiency of terminal equipment and the overall smoothness of operations.
