چکیده
The paper introduces two software tools for planning and operating an urban logistic center. The former software, called DiLog, is devised to determine the optimal assignment of delivery points to several possible terminals. It allows so the planner locating and sizing the terminals of the urban logistic system. Dylog is a dynamic software tool that allows the manager of an urban logistic base defining in real-time the best solution of the delivering program. The paper discusses also the related modeling framework and provides a concise description of the solution procedures, which are both based on a two-string genetic algorithm that solves the capacitated vehicle routing problem with multiple time windows. Finally, it describes the results obtained by simulating the operations at a logistic center located in the Italian town of Cosenza.
