Abstract: For improving the operation efficiency of stackers in Automated Storage and Retrieval Systems (AS/RS) of raw tobacco material, and solving the unbalanced operation problem for multi-stackers, an optimization model aiming at minimum total operation time of all stackers and well operation balance was presented. In this model, some optimization operation rules were introduced to replace the used rules. In order to search for optimum storage and retrieval serials, the coordinate system of this AS/RS was established, and two stacker time calculation methods of combined and single operations under full or low speeds were adopted. For a specific AS/RS case, the comparison before optimization and after optimization was carried out under the same parameters, it showed that the operation efficiency of all stackers could be increased by 82 packages per hour and the operation equilibrium among stackers was improved remarkably.
