1. A method for managing throughput performance of an automated storage and retrieval system, the method comprising:

  • providing a storage space with storage locations defined therein;

    transporting store units for storage in the storage locations and retrieving the store units from the storage locations with an automated transport system connected to the storage space; and

    managing throughput performance of the automated storage and retrieval system, with a control system operably coupled to the automated transport system and having more than one separate and distinct control sections each configured to, in response to and distinct from requests to input or output store units from the storage locations, manage throughput performance with respect to a common group of the storage locations, wherein at least one of the control sections independently manages request response aspects of throughput performance of the common group independent of another of the control sections, the request response aspects of the throughput performance being responsive separately from each of the requests to input or output store units from the storage locations but distinct from each of the requests to input or output store units from the storage locations, and a portion, determined by the independently managed aspects, of the throughput performance, with respect to the common group, managed by the at least one of the control sections is decoupled from another portion of the throughput performance, with respect to the common group, managed by the other control section.
