We perform the operation analyses of movable rack type AS/RS which is built in among manufacturing
resources. Processing time and processing cost to handle each pallet are investigated. We employ the
system simulator approach for the analyses. It is clarified that, if the operation conditions such as the
speed of the stacker crane and/or rack are properly adjusted, the processing time of each pallet is not so
increased in comparison with that in the fixed rack type case. Further, under our assumed conditions
concerning the investment, we found that the cost performance of the movable rack type AS/RS
accompanied with medium speed stacker crane is comparable with that of the fixed rack type AS/RS
equipped with high speed stacker crane.
