Abstract

For regular patient transportation and emergency transportation with ambulance vehicles a dynamic

dial-a-ride (DARP) problem has to be solved. We analyze two scheduling strategies for the

regular dial-a-ride orders in order to minimize routing costs and to maximize transportation quality.

Furthermore, we review practical requirements and suggest a conceptual architecture for a

decision support system based on a customary control center system as basis for future business

services.

Major results of this contribution are two promising and efficient solution procedures suitable for a

simplified bi-objective version of the dynamic DARP and tested with real-world problem instances.
