考虑订货时间影响的扩展供应链收入共享契约

在供应链的渠道协调中，传统的收入共享契约不考虑订货时间的影响，但是在基于时间竞争的时代，时间成为竞争的焦点，时间因素的影响不能被忽视。以供应链渠道成本和市场需求预测依赖于订货时间的收入共享契约为对象，研究扩展的收入共享契约对渠道协调的有效性以及在渠道协调下最优决策问题。证明考虑订货时间影响的收入共享契约能够使供应链渠道得到有效的协调，并建立了这类收入共享契约的最优决策模型，得出最优解存在的条件以及最优解的表达式并分析了需求参数变化对最优决策变量的影响，最后用一个数值实例将扩展的收入共享契约与传统的收入共享契约进行了对比。结果表明，前者能够使渠道成员的收益得到提升。

An Extended Supply Chain Revenue-sharing Contract with Consideration of Influence of Order Time

On supply chain coordination,order time isn't embodied in classic revenue-sharing model.But,in the time-based competitive age,time becomes the focus of the competition,and the influence of order time can't be neglected.A supply chain revenue-sharing contract with that the channel cost and the forecasting market demand rely on order time is discussed in this paper,and the validity of supply chain channel coordination by revenue-sharing and an optimal decision problem under the condition of the supply chain coordination is studied.It is proved that the extended revenue-sharing contract can coordinate the supply chain effectively;further,the optimal decision model is established,and the existent conditions and the(expression) of optimal solution are educed.In addition,effect of demand distribution parameters on the optimal solution are given;the extended revenue-sharing contract is compared with classic revenue-sharing contract by a numerical instance,and the result shows that the former can better the profit of supply chain actors.
