A FRAMEWORK FOR DISCRETE-EVENT SIMULATION OF PICK-UP-AND-DELIVERY PROBLEMS

摘要

So called pick-up-and-delivery problems are encountered in everyday life - for example parcel transportation, dial-a-ride services, and collection of mail from mail boxes. For modeling these problems, discrete-event simulation is a powerful technique that is able to handle complexties in a transportation system. In this paper, a new framework for discrete-event simulation of pick-up-and-deliviery problems are proposed. The framework includes a general and extensible library of simulation modeling components applicable to different types of pick-up-and-delivery problems. For evaluation, the proposed framework is used in the simulation-optimization on a real-world pick-up-and-delivery problem of waste collection.
