科学管理、精益管理与精确作战工程保障研究

设计是作战行动筹划的重要步骤,精确工程保障需要对工程保障行动进行精密的设计和精确管理与控制。科学管理采用科学实验的方法,通过劳动方法标准化和差别计件工资制度,有效提高了工作效率,其基本原理经过百余年的实际检验,被证明是一个成熟有效的管理方法。借鉴科学管理理论,需要对工程保障行动进行动作研究,进而研究工程保障行动的作业标准,以期提高其保障效率。精益管理是在科学管理在新的历史时期的发展与改进,它使用了准时制、零库存、均衡生产、持续改进等先进的管理理念和六西格玛管理、成组技术等先进技术,为基于信息系统体系作战的工程保障能力生成提供了有益的借鉴,可加深我们对精确工程保障的理解,促进精确工程保障研究的可操作性。

基于改进SLP的军事物流基地设施平面布局研究

由于传统SLP方法的不足,在解决设施较多的军事物流基地布局问题上面临较大困难。为解决此问题,提出了改进SLP方法,以军事物流基地设施间综合相互关系为基础,构建平面布局模型,并确定目标函数和主要约束条件。随后对模型的求解进行遗传算法设计,并运用Matlab编程实现模型的求解,从而得出平面布局的最优解。最后以最优解为基础,结合限制条件进行修正,完成军事物流基地设施平面布局设计。

Strategic outsourcing under technology spillovers

We study a supply chain in which an original equipment manufacturer (OEM) and a contract manufacturer (CM) compete in the finished goods market. The OEM can decide whether to outsource the intermediate good, a critical component for producing the finished good, from the CM or make in‐house production. Technology transition improves the CM's production efficiency, and it can take two different forms: a direct technology transfer from the OEM to the CM or technology spillovers through outsourcing from the OEM to the CM. We document the possibility of strategic outsourcing, that is, the CM supplies the intermediate good to the OEM when she is less efficient than the OEM's in‐house production. We find that technology spillovers can strengthen the incentive for strategic outsourcing. Furthermore, compared with direct technology transfers, outsourcing coupled with technology spillovers may generate more technology transition. Outsourcing is a particularly appropriate channel for implicit collusion when the OEM is not very efficient with the production of the intermediate good. Our results suggest that ex post competition on the finished goods can create room for ex ante collaboration and provide some implications on the OEM's outsourcing strategies when facing a competitive CM.© 2014 Wiley Periodicals, Inc.

基于流量均衡和跨层技术的星群路由算法

针对分布式星群网络业务通信QoS不高的问题,提出了一种基于流量均衡和跨层技术的分布式星群网络路由算法(TACA)。该算法首先通过跨层技术将物理层、MAC层的相关信息搜集起来,作为判断链路负载状况的依据;然后对不同类型的业务进行分类,根据链路负载状况和业务QoS级别选择不同的路由层次,从而均衡流量以提高QoS。仿真表明,该路由算法在一定程度上降低了星群的呼叫阻塞率和切换阻塞率,平衡了网络的负载,提高了网络吞吐量。     

Offsets as industrial policy: Lessons from aerospace

Since 1975 “offsets” have begun to appear frequently in contracts covering international sales of aircraft and other products incorporating advanced technology. Offsets involve reciprocity beyond that normally found in an exchange of goods for money. They may involve co‐production or co‐design of the principal item to be exchanged, or acceptance by the seller of goods or services unrelated to it as partial payment (indirect offsets or countertrade).

The United States has become the major provider of offsets and anti‐offset sentiment has grown. Economists interpret them as trade diverting. Politicians from regions suffering loss of employment view them as bestowing unfair advantage to foreign competitors.

The authors examine offsets from both theoretical and policy perspectives and conclude that in such noncompetitive markets, second‐best considerations dominate, requiring case‐by‐case evaluation of impacts and rendering across‐the‐board determinations of welfare loss suspect.     

The “yellow rain” controversy: Lessons for arms control compliance

Indonesia, Thailand, and Vietnam recently announced that they are launching nuclear energy programs, and Malaysia and the Philippines soon may follow suit. As a result, by 2020, at least three states in Southeast Asia could possess latent nuclear capabilities—the option to pursue military applications of dual-use nuclear technology. Analysis of the nuclear programs, domestic proliferation pressures, and the external threat environment in Southeast Asia leads the authors to conclude that the nuclear intentions of states in that region are entirely peaceful and the probability of future nuclear breakout there is low. However, this finding does not justify complacency. In the long term, the benign outlook for regional security may change, and in the near term weak regulatory regimes present serious challenges to nuclear safety and create opportunities that non-state actors may exploit. To minimize these risks, the authors recommend creating a “proliferation firewall” around the region, which would combine strong global support for Southeast Asian nuclear energy programs with innovative regional multilateral nuclear arrangements.
