A multi-layered model for dynamic supply chain configuration

This research proposes a new model representing multi-layered dynamic supply chains. The proposed model consists of three kinds of components. They are clients, manufacturers, and suppliers. The manufacturers, proposed in this research, not only generate the orders to the suppliers but also generate the offers to the clients. The manufacturers continue to modify their production schedules after sending the orders to the suppliers, in order to get the contract with the clients, even if the possible delivery time from suppliers do not satisfy the required delivery time from the manufacturers. The effectiveness of the proposed model is verified through some computational experiments from the viewpoint of the completion of the contracts.
