Abstract: Aiming at the crane scheduling problem of automated warehouse in multi-I/O station,the required operating time was taken as the evaluation criteria to present a new scheduling model based on mixed command sequence by analyzing operating modes of crane in different tasks.On this basis,genetic algorithm was used to optimize the scheduling path of crane,and crane scheduling model of multi-I/O station was analyzed with simulation cases.The result showed that the proposed crane scheduling model and optimization method could improve the storage efficiency in multi-I/O station automated warehouse.

Key words: automated warehouse, distributed access pattern, crane, scheduling modeling, path optimization, genetic algorithms
