Failure and restart of an aisle : solutions for a hidden problem with significant effect in high bay racking systems for warehousing

Wildner, Christian

Fulfilling essential functions in transport and distribution logistics, industrial warehouses are usually equipped with automatic high bay racking systems, the aisles and especially the automated storage/retrieval systems of which happen to fail temporarily in the course of operation. The common operating strategy "uniform aisles distribution" prepares warehouse control systems for such cases of failure: the operation of the total system is usually kept up with reservations during the down-time of a single aisle. But when the necessary restoration has been carried out and the control system restarts the aisle – the efficiency of the total storage system doesn’t recover to its original level but temporarily decreases even more. This paper explains the underlying causes of this problematic effect and points out its possible consequences. Furthermore possible solutions are indicated.
