Using Logical Time to Ensure Liveness in Material Handling Systems With Decentralized Control

Seibold, Zazilia; Furmans, Kai ORCID iD icon; Kevin, R.

Abstract (englisch):

We describe a method for decentralized control of route-based material handling systems in which devices have no central controller (by definition), no common source of information, and no synchronized or common clocks with which to plan and execute their activities. The control scheme is based on the concept of \emph{logical time}, which is a means of partially ordering events in computer operating systems. We modify the concept to the domain of material handling systems and prove system liveness. We conclude by describing GridSorter, a conveyance-based sorter that uses decentralized control and logical time to sort packages. A prototype has been successfully built and tested at the Institute for Material Handling and Logistics at Karlsruhe Institute of Technology.
