A procedure for solving vehicle routing problems is important to reduce the logistics cost and to enhance the overall performance of the enterprise system. In this study we investigated vehicle routing problems under three different vehicle speeds. An efficient heuristic which can consider the dynamic environment is developed and examined with various problems. In this environment the moving speed between two points is not the same all the time. The speed is determined based on the time that the vehicle actually passes. It is found that the developed heuristic can be used to find an optimum or near optimum vehicle route by simulation studies.
