Vehicle-Based internal transport systems are widely used in many industrial facilities such as warehouses, distribution centers and production facilities. In most vehiclebased internal transport systems, on-line dispatching rules are used to control vehicle movements. Single-attribute dispatching rules, which dispatch vehicles based on one parameter such as the load waiting time, are used popularly in practice. Examples of these rules are modified-first-come-first-serve and nearest-workstation-first rules. Hybrid dispatching rules are more complicated and dispatch vehicles using several parameters and types of vehicle assignments. The major advantage of single-attribute rules is that they are simple and easy to implement in practice, but their performance can be improved. In this research, we propose new dispatching rules and compare their performance with several single-attribute and multi-attribute dispatching rules in literature. Experimental results show that our new dispatching rules are robust and perform very well in general.
