非对称生产模型供应商的两阶段投标策略

Under the condition that small capacity suppliers only can attend the second stage bidding,this paper consider inviting suppliers with different capacities to a procurement auction,which adopt sequential second price sealed mechanism.By formulating game theoretic models,the optimal strategies of both suppliers are generated.The results show that although the expected procurement cost is reduced,the large size suppliers will enlarge uheir bidding price at the first stage.The additional procurement cost will be increasing with more small size suppliers' involvement.
