Abstract: Optimizing the order picking is an important strategy to improve the working efficiency of automated warehouse. According to the requirements of order picking tasks of the fixed shelve, a mathematic model is constructed. An improved ant colony algorithm for the order picking problem is designed. Three improvements are adopted: awaiting nodes set, selection operator and dynamic change on algorithm parameters. Simulation results demonstrate the approach has better overall search ability and quickly astringency, satisfying the demands of medium or large scale work.

Key words: improved ant colony algorithm, automated warehouse, order picking, combinatorial optimization problem
