| 摘 要： | 考虑生产商、销售商联合库存的动态优化问题,建立的随机需求下生产-销售运作系统的排队模型,得到了系统的稳态概率分布和队长分布.以成本最小化为目标,模型算法找到了最优的运作策略和机器使用数量.数值模拟的结果表明,依赖于指定机器数量的动态调整策略明显优于静态系统.

Dynamic joint Inventory Decision Model and Algorithm |
| |
| Abstract: | Under random demand,decision of joint inventory are always influenced from manufacturers and vendors stand-alone decision,by setting up a group of flexible machines can be switch,dynamic adjusting production resources of system,achieve effective control of inventory levels.Using two queueing models to quantify key performance indicators in system operating and some parameters between changing relationships,obtain the steadystate probability distribution and the queue length distribution.Proposed algorithm find the optimal operation strategy and minimum number of machines usage,the numerical simulation demonstrate that the results of dynamic decision depend on the number specified machine is superior to the static system. |
