Abstract

Automated Storage/Retrieval Systems (AS/RS's) is a system that consists of storage and retrieval functions which can be operate automatically in a manufacturing facility and are widely used in warehousing and manufacturing applications. This system has many applications which include storage location assignment rules, zoning procedures, stacker movement, and incoming and outgoing queue priority and sequencing rules. Those applications were evaluated by grouping control variables and testing the significance of these variables on system performance. Among of these are automated for collectively known in the warehousing industry as materials handling systems. Typically the material handling system is used in such applications where storage density is important because of space constraints. Most systems operate in a fully automated mode with little or human involvement in the handling of material except at the controlled input and output stations to the system. AS/RS consists of storage racks, S/R machines, link conveyors, and input/output (110) stations. The system performance is measured throughout the capacity of the system. The service time for a transaction includes both SIR machine travel time and pickup/deposit time. This time typically depends on the configuration of the storage rack and the S/R machine specifications. The are several benefits of this system among them reduces warehouse operating costs, low storage space requirements good collection preservation, low ongoing costs and cuts cycle time by eliminating waiting time, walk, and search time for operator bringing the material.
