摘要：
In this paper, we study dual sourcing mode and single sourcing with emergency option mode in a decentralized supply chain to deal with supply disruption. Then we study how to choose between them through comparing the homogeneity and heterogeneity of wholesale price and supply reliability. It is shown: when the suppliers are homogeneous both in wholesale price and supply reliability, single sourcing with emergency option mode is better than dual sourcing mode, except in the following two special conditions: the wholesale price of the two is much lower compared with the option price and at the same time the dispersion degree of reliability is small enough, or the reliability of the two is both very high; when the two suppliers are heterogeneous in wholesale price, the optimal mode is turning from dual sourcing mode to single sourcing with emergency option mode as the heterogeneity rises; when the two are heterogeneous in supply reliability, the optimal mode is turning from single sourcing with emergency option mode to dual sourcing mode as the heterogenicity rises.
