Robustness Comparison of Three Coastal Dual Channel Supply Chains under Two-Factor Disruptions

There is still a lack of comprehensive comparison of optimal pricing, and ordering strategies for three coastal dual-channel supply chains (SC) under simultaneous disruption of demand and production cost. Firstly, three kinds of coastal dual-channel SC structures with different cooperation modes are proposed. Based on retailerled Stackelberg game and linear price discount sharing (PDS) scheme, the optimal two-stage pricing and ordering strategies of three coastal dual-channel supply chains were solved when demand and production cost factors were disturbed. Then, their robustness under the interruption of demand and production cost was compared and ranked. The results show that no SC structures always has the best robustness when both demand and production costs are interrupted, and sequence of robustness is determined for each feasible disruption range.
