After reviewing related studies in Section 2, this paper will present a framework for a real-time vehicle dis-
patching system in Section 3. The system is composed of seven modules, i.e. Discrete Event Manager, Vehicle
Manager, Order Manager, Product Manager, Customer Manager, DC Manager and GIS Manager. The real-
time system generates route plans in the dynamic environment in two phases: initial route dispatching and
route improvement. Section 4 examines the parameter settings through a complete ANOVA analysis. After
the experimental work, cases will be suggested for different performance requirements. Section 5 concludes
the study
