The Calculation of Average Operation Cycle Time on Curve-Type Stacker Under FIFO Condition

Curve-rail type stacker is the key equipment for goods automatic access in automated high-rise warehouse. This paper analyzes the different operation conditions of curve-rail type stacker, derives the cycle time calculation formula of single-task and multiple-task operations of curve-rail type stacker under unequal probability, puts forward the method of using traversal algorithm to calculate the average operating cycle time, discusses slotting optimization plan by means of activity based classification (short for ABC), and makes example analysis and research on the laboratory data of South China University of Technology. The research results provide decision-making basis for the operation planning and efficient management of enterprise automated high-rise warehouse.
