不同订货策略下周期服务水平相对稳定性研究

Comparative Analysis of Service Level in Supply Chain under Different Replenishment Policies

分别在周期盘点和连续盘点订货策略下,研究了供应链周期服务水平的确定。研究表明:销售剩余的处理方式和成本分担方式对服务水平有较大的影响;合作情况下,周期盘点订货策略的服务水平在销售季节的大部分时间保持了稳定性;建立了存在数量折扣和运费折扣的随机型连续盘点订货模型,证明了由该模型确定的服务水平对于订货批量的相对稳定性。

In single cycle and multi cycles replenishment policies,as the surplus is disposed by the seller or supplier,the authors compared the cycle service level in non corporation：the seller and supplier undertakes desposing cost all by himself;and in corporation of joint decision and cost shared.The corresponded replenishment policies are also analyzed.The concluusion is that when seller disposes,the optimal level of cost shared is higher than not shared;when supplier disposes,the optimal level of cost shared is lower than not shared.The optimal level in single cycle is lower than that in multi cycles policy,in the same corresponding strategy of cost sharing.
