Abstract
Freight transportation generates external diseconomies, such as traffic congestion and air pollution. Logistics centers interconnected with expressways could contribute to alleviating these problems. This study aims to develop analytical models and simulation models in order to optimize the number of berths in a truck terminal, which is constructed in logistics centers. At first we determine the arrival and service-time distributions of trucks in a truck terminal. Then the models are built up based on queuing theory. We apply them to the berth-planning in an existing truck terminal, and finally the effects of various factors on the number of berths are examined by using the models.
