Holonic-based control system for automated material handling systems
… constraints, a feasible schedule for the material handling resources emerges from the combination of individual holon's schedules. Internal evaluation algorithms and coordination mechanisms between the entities in the architecture form the basis for the resultant schedules. The …

Simulation modeling of material handling systems: requirements and comparative analysis
This thesis identifies various material handling model parameters which must be addressed when using simulation. Operations of six material handling devices (AGVS, AS/RS, conveyors, cranes, fork trucks, and industrial robots) are studied to determine attributes which require modeling consideration. …

The impact of vehicle dispatching on the design of multiple-transporters material handling systems
Although Automated Guided Vehicle Systems (AGVS) have been around for more than thirty years, designing an AGVS is still a difficult process because of the interaction of numerous system decisions. The many important elements and variables that must be considered when designing AGVS include the …

Evaluation of Unit Load Stability Under Dynamic Forklift Handling Conditions
… where the pallet is the base of the unit load. Material handling systems represent the physical environment in which unit loads are transported through supply chains. Material handling systems include different transportation modes and storage conditions, many of which are well researched. While …

Integration of operation allocation and material handling in the design of flexible manufacturing systems.
Operation Allocation and Material Handling Systems Selection are important functions of a manufacturing system and as such must be considered within an integrated approach to manufacturing systems design. This work, an extension to the work done by Paulo (1999) proposes to integrate two important …

Characterization of Performance, Robustness, and Behavior Relationships in a Directly Connected Material Handling System
In the design of material handling systems with complex and unpredictable dynamics, conventional search and optimization approaches that are based only on performance measures offer little guarantee of robustness. Using evidence from research into complex systems, the use of behavior-based …

Integrated Scheduling and Material Handling: Theory and Applications in Manufacturing Systems
… tasks over time and is central to manufacturing systems. In practice, production scheduling is tightly linked to material handling, as jobs must be transported between machines, buffers, and storage locations. However, transportation decisions have often been simplified or decoupled from …
