Abstract: To explore the impact of upstream structure on supply chain design, according to characteristics of Bill of Material (BOM), and correlations with multi-hierarchical attributions of suppliers, the concept of supply hubs embedded BOM was introduced to establish three supply chain design models with no supply hub, one supply hub and two supply hubs, respectively. These three Mixed Integer Programming (MIP) models were computed by using combined genetic algorithm. The case study found that the total cost and inventory level of supply chain designed with supply hubs was lower than without supply hub in the same period, meanwhile the supply chain designed with supply hubs, particularly for with two supply hubs, inhibited ‘Bullwhip effect’ more effectively than without supply hub.
