Supply chain should be continuously designed and redesigned in order to dynamically configure suitable clients and suppliers in multiple supply chains. Previous researches proposed a dynamic configuration method of two-layered supply chains consisting of a set of clients and suppliers. The proposed method provided suitable delivery times and prices of products by the negotiation between clients and suppliers and by the modification of existing production schedules of suppliers. This research proposes a new model of two-layered dynamic supply chains considering transportation constraint. The new model provides a method for the suppliers to estimate delivery times and prices of products based on not only production schedules but also transportation plans that 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 experimental results showed that the prototype system obtained a set of suitable shipping times and loading capacities.
