Product storage policy,single picking volume and picking routing are the three factors of vital importance that affect the efficiency of a crane to pick goods in automated storage and retrieval systems (AS/RS).Comparative experiments on picking efficiency were conducted targeting picking operation with order of 1 to 20.Based on dedicated and random storage policies,4 picking methods of patching-based,S-type,return-type and optimized-type routes were used and compared in the experiments.The results show that either the dedicated policy or the random policy was applied,crane worked most efficiently with optimizedtype route,followed by S-type path,patching-based path,and return-type path.When the number of orders in a single picking is larger (more than 5),the random storage policy is preferable to the dedicated policy.
