供应链中基于延期交货的批量订货策略

对1个卖方、2个买方的供应链系统,买方的地位相等,其需求为固定的常量.在通常的数量折扣模型的基础上允许缺货或延期交货,并以此来研究卖方定价对买方订货策略的影响,但先决条件是不损害供应链所有成员的利益.从其结果看,适当时长的缺货或延期交货对卖方以及买方都有很大的好处,与没有缺货的情形相比,虽然某些时候订货数量少了一些、价格高了一些,但链中所有成员的成本节省却大大增加.

Lot order policies based on lead time in supply chain

In a supply chain system with one supplier and two buyers, the buyers' status are equal and their demands keep constant. Based on typical quantity discount models, out-of-stock or lead-time is allowed. Hereby, the effect of the supplier's pricing on the buyers' order policies is studied with a precondition that the benefit of all members in supply chain should not be damaged. According to the results, appropriate time length for out-of-stock or lead-time is of benefit to both supplier and buyers. Compared with no out-of-stock, although sometimes order quantity decreases and price goes up somewhat, the cost saving of all members in the chain would increase remarkably.
