Abstract
This research proposes a new model of two-layered dynamic supply chains considering transportation constraint. The new model provides a method for suppliers to estimate delivery times and prices of products based on not only production schedules but also transportation plans. The transportation plans generally include constraints about shipping times and loading capacities for transportation. A prototype of dynamic supply chain simulation system was developed and some computational experiments were carried out in order to verify the effectiveness of the new model. The prototype system is available to determine suitable shipping times and loading capacities of transportation vehicles.
