B2B 在线市场期权合同协调的鲁棒策略

在B2B在线市场的不确定环境下,考虑长期合同的稳定性和在线现货采购的灵活性,设计了基于期权合同协调在线市场与传统市场的鲁棒策略.在B2B在线市场最坏需求情景下,研究了卖方作为主方、买方作为从方的主从对策模型.应用鲁棒优化理论,提出B2B在线市场环境下求解买方定货量及卖方期权合同预定费用和执行费用的鲁棒Stackelberg解的算法.最后,结合上海宝钢益昌公司电子商务问题,仿真计算求解了鲁棒定货量、期权合同预定费用和执行费用,并进行了实证分析.

Robust Strategies for Option Contract Coordination in B2B E-markets

Under the uncertain environment of B2B e-markets,the stability of long-term contract and the flexibility of online spot purchasing are considered together,and the robust strategies for coordination between e-markets and traditional markets based on option contract are designed.Under the worst demand scenarios of B2B e-markets,the strategies of stackelberg game in which seller is the leader and buyer is follower are studied.Applying the theories of robust optimization,the algorithms of solving the robust solutions of buyer's order quantity and seller's contract reservation costs and execution costs in B2B E-markets are brought forward.Finally,combining with the e-commerce practice of Shanghai Baosteel Yichang Corporation,the demonstration analysis is carried out,and the robust order quantity,contract reservation costs and execution costs are worked out through simulating calculation.
