The choice of system follows your item structure and access frequency \u2013 not the floor space available. For small parts with high access density and limited footprint, a cube storage or shuttle system is usually the most economical option. With a few thousand items and moderate access rates, vertical lift modules are sufficient. For pallets, high-bay racking with a stacker crane remains the benchmark. Ultimately, however, project success depends less on the mechanics than on the integration: without a clean interface between the automated storage system and the warehouse management system<\/a>, the promised throughput stays unused.<\/p>\n\n\n\n

The system types compared<\/h2>\n\n\n\n

All throughput figures are guide values per machine or per installation and depend heavily on item range, order structure and the number of picking stations.<\/p>\n\n\n\n

Five steps to a sound decision<\/h2>\n\n\n\n
    \n
  1. Analyse item and order structure.<\/strong>\u00a0Accesses per item over twelve months, ABC distribution, lines per order, bin and weight classes. Without this data, any system recommendation is guesswork.<\/li>\n\n\n\n
  2. Calculate for the peak, not the average.<\/strong>\u00a0What matters is the peak hour of the peak day, not the annual mean. A peak factor of 2 doubles the required system throughput.<\/li>\n\n\n\n
  3. Check the structural constraints.<\/strong>\u00a0Usable ceiling height, floor load capacity and flatness, column grid, fire protection concept and escape routes. These points rule systems out faster than any business case.<\/li>\n\n\n\n
  4. Define the growth path.<\/strong>\u00a0Modular, expandable systems cost more initially but avoid a full system replacement if volumes double within three years.<\/li>\n\n\n\n
  5. Settle the integration before the mechanics.<\/strong>\u00a0Decide which system owns the storage strategy \u2013 your WMS or the machine manufacturer’s controller. That decision shapes processes and follow-up costs more than the choice of hardware.<\/li>\n<\/ol>\n\n\n\n

    Why integration decides the outcome<\/h2>\n\n\n\n

    An automated storage system only delivers the throughput stated in the specification if orders arrive in the right sequence and at the right pace. That is precisely the job of the material flow control layer between the warehouse management system<\/a> and the machine technology. At proLogistik Group, the pLG Automation<\/a> module fills this role: it connects conventional conveyor technology, shuttle systems, automated small parts warehouses and AGVs to pLG WMS and coordinates transport within the installation.<\/p>\n\n\n\n

    For AutoStore<\/a> installations, a direct connection is also available via the pLG Autostore Connector. The practical benefit: there is no need for a subordinate sub-WMS to run the installation. Stock, strategies and order control stay in one system instead of being reconciled between two data sets \u2013 fewer interfaces and less day-to-day coordination effort.<\/p>\n\n\n\n

    A second point is often underestimated: whoever connects one system today will typically connect a second one within five years. A vendor-neutral WMS with standardised interfaces keeps that option open. A machine controller that only knows its own hardware does not.<\/p>\n\n\n\n

    Three mistakes that make automation projects expensive<\/h2>\n\n\n\n
