Abstract: Sequence optimization of loading/unloading is a key technique for crane to realize the automatic and smart operation, and improve the operation efficiency. The analysis model of conveyance operation of crane is constructed, and the operation environment and cargo states are defined. Furthermore the cargo position information database is built. The problem of loading and unloading sequence of crane is formulated, and a new search and optimization method is suggested by limiting the number of searching objects in the calculation of the minimum conveyance distance according to the practical operation of crane. Consequently, an effective generation rule, optimization method, and automatic generation technique of loading/unloading sequence for crane are proposed. The effectiveness of the suggested method is validated by numerical simulation. The results show that the suggested method can automatically and rapidly generate the cargo handling sequence, thus the effective and continuous conveyance of large scale cargo can be realized. The suggested method provides technique support for crane to achieve smart operation.
