摘　　要：研究了基于提前期压缩的信息对称和信息不对称两种情况下的供应链协调问题,重点解决了在信息不对称时采用线性转移支付策略解决供应链的不协调问题.当压缩提前期时,制造商的成本增加,成本的增加值信息对销售商有对称和不对称两种情况.在信息对称时采用收益共享契约可以实现供应链的协调;在信息不对称,采用收益共享契约时,为了激励制造商,销售商不得不对制造商生产成本的不确定性付出成本,导致利润下降,而制造商由于拥有私有信息而使得利润增加,所以整个供应链并没有达到集中决策时的水平,只得到了帕累托改善的次优结果.创新点在于采用线性转移支付策略实现了供应链的协调,达到了帕累托最优,解决了收益共享契约不能实现供应链协调的问题.最后通过算例进行了说明.This paper studies the supply chain coordination of lead-time compression of symmetric information and asymmetric information problems based on two cases, and solves the problem of inconsistent linear transfer payment strategy to optimize the supply chain in the information asymmetry. When the compression time, manufacturers increased cost, cost value added information on vendors have symmetry and asymmetry in two cases. Co- ordination with revenue sharing contract can achieve supply chain under the conditions of symmetric information; the information asymmetry, the revenue sharing contract, in order to encourage manufacturers, distributors to manufacturers cost uncertainty, cost, leads to decrease in profits, while manufacturers with private information and make profit increase, so the whole supply chain does not achieve the centralized decision-making level, only got Pareto to improve sub-optimal results. The innovation of this paper is using the linear transfer payment strategy to achieve supply chain coordination, to achieve the Pareto opti- mal solution, the contract can not coordinate supply chain issues of revenue sharing. Finally, illustrated with examples.
