In this paper, a timed-place Petri net (TPPN) model for flexible manufacturing systems
(FMSs) is constructed, which contains two major submodels: the stationary transportation …

Bidirectional AGV systems are intuitively more attractive than unidirectional systems in terms
of efficiency because of shorter travel distances. An efficient algorithm for finding conflict-free …

In a large-scale wireless sensor traffic network, collecting and processing of the global real-
time traffic information are often unreliable. Making real-time navigation decision becomes …

Because of their routing flexibility, automated guided vehicles (AGVs) have been used in
many manufacturing systems, especially those in which parts with diverse and complex …

We consider a manufacturing job shop with automated guided vehicles. Such a system is
characterized by several complex features such as the random pattern of material flows …

Centralized and distributed automated guided vehicle system (AGVS) models for materials
handling, and the model for part processing are integrated into a single coherent model …

(57) ABSTRACT A system for transporting inventory items includes an inven tory holder and
a mobile drive unit. The inventory holder has a frame with device openings. The mobile drive …

A mobile drive unit is provided for transporting an inventory holder. The mobile drive unit is
operable to dock with the inventory holder, move the inventory holder in a first translational …
