Limit Performances and Queuing Effects

Abstract

Logistic, production and performance stations, systems and networks are passed by discrete objects [DO]. These objects are logistic units, like article units, load units or vehicles, and information units, like orders, documents, data and other digital information. Within the stations the objects are consumed, processed, generated, assembled or dispatched. The limit performances of the stations and transport elements determine the performance capability of the total system. Waiting queues extend the transfer times from the entries and sources to the exits and sinks. Hence, for the design of new systems and the optimisation of existing systems, the limit performances and the queuing effects must be known.
