In this paper, we describe a search method based on the language PDDL for solving vehicle routing problems. The Vehicle Routing Problem (VRP) is a classical problem in Operations Research, and there are many different variants of the VRP. This paper describes a new approach to model standard VRP and some variants based on PDDL language, explains how the method constructs model and solves the problem using several PDDL planners, and analyses the planning results of these planners.
