Comparison of performance measurement-systems used for order-picking

In consequence of rapidly changing market demands companies are permanently encouraged to review their own processes and structures and to modify them. Being one of these developments, order-picking is involved as part of an intra-logistics system. But to take appropriate actions, system performance and system costs have to be measured permanently. Concerning this the use of performance measurement-systems as further development of traditional systems of key figures is suitable. In this paper various performance measurement-systems are compared and their suitability for an implementation in order-picking systems is estimated. On the basis of the result of the evaluation a first concept of a performance measurement-system for order-picking will be developed by using typical key figures that are mentioned in academic literature. Finally, hints for a necessary detailed implementation and evaluation in practice will be given.

Bestimmung der Leistungsverfügbarkeit eines modularen Sorters

Der GridSorter ist ein dezentral gesteuertes, modulares Fördersystem, das zur effizienten und platzsparenden Warensortierung genutzt werden und flexibel an wechselnde Anforderungen angepasst werden kann. In diesem Artikel wird ein Steuerungsverfahren vorgestellt, welches automatisch auf technische Störungen reagieren kann und somit einen kontinuierlichen Betrieb ermöglicht. Mittels Simulation wird der Einfluss von Defekten einzelner Module auf die Systemleistung untersucht.
