On the first come–first served rule in multi‐echelon inventory control

A two‐echelon distribution inventory system with a central warehouse and a number of retailers is considered. The retailers face stochastic demand and replenish from the warehouse, which, in turn, replenishes from an outside supplier. The system is reviewed continuously and demands that cannot be met directly are backordered. Standard holding and backorder costs are considered. In the literature on multi‐echelon inventory control it is standard to assume that backorders at the warehouse are served according to a first come–first served policy (FCFS). This allocation rule simplifies the analysis but is normally not optimal. It is shown that the FCFS rule can, in the worst case, lead to an asymptotically unbounded relative cost increase as the number of retailers approaches infinity. We also provide a new heuristic that will always give a reduction of the expected costs. A numerical study indicates that the average cost reduction when using the heuristic is about two percent. The suggested heuristic is also compared with two existing heuristics. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2007     

面向军队财务管理领域的军事大数据应用

随着“大智移云物”的出现和发展，战争形态已经发展到智能化战争新阶段。为了打赢未来智能化战争，推进军队财务管理实现智能化，充分利用军事大数据这一新兴重要战略资源尤为必要。本文利用需求分析法和现象分类法，从经费需求测算、预算编制、军费支出和军费绩效评估四个方面分析了军队财务管理领域应用军事大数据的需求。针对当前存在的运用军事大数据观念淡薄、数据采集困难、数据挖掘处理能力较弱、数据安全威胁及军事大数据人才缺乏等五个问题，从大数据应用观念的树立、软硬件设备的更新、数据中心的建设、应用框架的构建、信息化管理制度的完善、数据安全管理和大数据人才队伍建设几个方面提出了在军队财务管理领域应用军事大数据的思路。
