Abstract: To improve the running efficiency of automated warehouse,numerous enterprises adopted the warehouse layout model which used double-crane on single roadway with two I/O station.For the problem of double-crane scheduling,the anti-collision principle was taken as the basic principle and the required operating time of two cranes as the evaluation criteria to present a new scheduling model based on mixed command sequence by analyzing the operating modes of double-crane in different tasks.On this basis,Improved Chemical Reaction Optimization (ICRO) was used to optimize the scheduling path of double-cranes.According to the analysis of simulation,the proposed crane scheduling model could adopt the warehouse operating condition and avoid the collision.Meanwhile,the optimization algorithm could improve the storage efficiency for double-crane on single roadway with two I/O station model.
