A container unloading planning system is a software solution that orchestrates the entire discharge operation at a port or container terminal: sequencing container lifts from the vessel's stowage plan, assigning cranes and yard slots, and coordinating landside connections to truck and rail. The primary objective is to minimize berth occupancy while maximizing throughput. These systems are typically embedded as a module within a Terminal Operating System (TOS), exchanging real-time data with crane dispatch, yard management, and gate systems. Unlike a standard warehouse management system, a discharge planner must incorporate vessel stability constraints—trim and list—into the sequencing logic to keep the ship safely balanced throughout the operation.
