Description

Shuttle vehicle task allocation scheduling method, vertical library system and computer storage medium Technical Field The invention relates to the technical field of logistics, in particular to a shuttle task allocation and scheduling method, a vertical warehouse system and a computer storage medium. Background In recent years, with the rapid development of intelligent manufacturing enterprises, the application and management of logistics systems are becoming more important. The shuttle vehicles used in the material warehouse are, for example, RGV trolleys (Rail Guided Vehicle, rail guided vehicles), and can carry logistics, but the path planning and task scheduling technology of the plurality of shuttle vehicles are key factors affecting the current sorting efficiency. However, the current solution has many disadvantages, such as the inability to effectively cope with complex scheduling tasks, the realization of dynamic scheduling in the process, and the low handling efficiency, and the current path planning algorithm usually plans the shortest cargo access path for a single shuttle.
