论陈毅在黄桥决战中的统战艺术

1940年,黄桥事变爆发。为了赢得这场反顽战斗的胜利,陈毅在分析了苏北的局势后,展开了成功有效的统战工作。首先,针对苏北的战略态势,陈毅提出“联李、击敌、反韩”的斗争策略;其次,让出吴家桥地区,争取“二李”协助新四军东进;再次,命令新四军撤出姜堰,争取“二李一陈”严守中立。陈毅以高超的统战艺术为新四军取得这次反顽胜利奠定了基础。同时,陈毅的统战艺术对当前武警部队遂行多样化任务,也有着极重大的现实启示。     

Stein–Chen approximation and error bounds for order fill rates in assemble‐to‐order systems

Assemble‐to‐order (ATO) is an important operational strategy for manufacturing firms to achieve quick response to customer orders while keeping low finished good inventories. This strategy has been successfully used not only by manufacturers (e.g., Dell, IBM) but also by retailers (e.g., Amazon.com). The evaluation of order‐based performance is known to be an important but difficult task, and the existing literature has been mainly focused on stochastic comparison to obtain performance bounds. In this article, we develop an extremely simple Stein–Chen approximation as well as its error‐bound for order‐based fill rate for a multiproduct multicomponent ATO system with random leadtimes to replenish components. This approximation gives an expression for order‐based fill rate in terms of component‐based fill rates. The approximation has the property that the higher the component replenishment leadtime variability, the smaller the error bound. The result allows an operations manager to analyze the improvement in order‐based fill rates when the base‐stock level for any component changes. Numerical studies demonstrate that the approximation performs well, especially when the demand processes of different components are highly correlated; when the components have high base‐stock levels; or when the component replenishment leadtimes have high variability. © 2012 Wiley Periodicals, Inc.
