Pricing and optimization of inventory system for a finite time horizon with discount rate 有限计划期内带有折扣的库存系统的优化及其定价
The research object of this paper is single product logistics distribution system of one - many network with the properties of d - system . it makes a discussion about fixed plan period irp under definite condition of customer demand , and explains why it does so 明晰了本文以具有d ? system特性的one - many拓扑结构的单物品物流配送系统为研究对象,讨论客户需求确定条件下的固定计划期长度库存?路线问题( irp ) ,并给出从该角度研究irp的原因。
Operation management ' s mission is planning and attempering every devices of transaction , programming paths of transaction on the basis of wants of production process . so the material wanted can smoothly arrive correct position in time . it includes operation planning as well as operation controlling 生产物流计划的核心是生产作业计划的编制工作,即根据计划期内规定的出产产品的品种、数量、期限,以及发展了的客观实际,具体安排产品及其零部件在各工艺阶段的生产进度。
Secondly , in the first phase , this paper solves the inventory supplement sub - problem through integer programming model , using the reduction of vehicle routes as the breakthrough to this problem , divides a whole distribution region into many customer subsets by radius - circle partitioning method , determines the optimal number of vehicle of service distribution region , applies two practice - oriented conclusions to reduce the number of routes on the basis of customer grouping , thus decreases considerably the variable scale of integer programming , and solves the problem through professional software to fix inventory supplement plan in plan period 其次,在第一阶段使用整数规划数学模型来规划库存补充计划子问题,以减少车辆巡回路线数目为求解该整数规划的突破口,提出与固定划分策略( fpp )相似的客户分组思想,通过径?环切割法把整个配送区域划分成多个客户子集,实现客户分组并确定服务整个配送区域的最佳车辆数目。在客户分组的基础上建立了精简路线的整数模型,然后通过运用两条基于实际经验的判断来进一步减少巡回路线数目,进而极大地减少了整数规划的变量规模,并利用专业的求解软件来求解该整数规划问题,从而确定计划期的库存补充计划。
