COURTING THE GLOBAL SOUTH WITH “DUAL-BENEFIT” NONPROLIFERATION ENGAGEMENT

President Barack Obama and an array of other Western leaders continue to assert that the spread of weapons of mass destruction (WMD) to non-state actors is one of most pressing challenges to global security today. Yet, Western efforts to engage governments—particularly governments across the global South—in a practical nonproliferation dialogue have largely yielded disappointing results. This viewpoint examines the need for a new strategy to engage the developing world in nonproliferation programs. It argues that strategies focused strictly on WMD nonproliferation are unsustainable, and ultimately are destined for failure. An alternative “dual-benefit” nonproliferation engagement strategy utilizes the enlightened self-interest of partner governments needed to achieve broad-based buy-in among all partners. In a concluding section, we recommend that the “Group of 8” Global Partnership Against the Spread of Weapons and Materials of Mass Destruction standardize this model of nonproliferation engagement as it sets out to identify and fund WMD nonproliferation capacity-building initiatives beyond the states of the former Soviet Union.     

资源约束条件下的空中兵力编组

通过对空中兵力的合理编组,实现作战资源的优化配置是提升兵力作战效能的有效途径。针对现代空战编队对抗过程的特点,从战术企图和信息优势角度提出了编队目标威胁评估方法。以编队目标为研究对象从宏观上调配己方作战资源,提出了作战资源成本和兵力调度成本2种兵力编组成本,在此基础上建立了资源约束条件下的兵力编组优化模型,并采用改进PSO算法对模型进行求解。作战想定仿真结果表明兵力编组模型能够有效解决空战兵力分配问题。

Operations sequencing for a multi‐stage production inventory system

This article studies operations sequencing for a multi‐stage production inventory system with lead times under predictable (deterministic) yield losses and random demand. We consider various cases with either full or partial release of work‐in‐process inventories, for either pre‐operation or post‐operation cost structures, and under either the total discounted or average cost criteria. We derive necessary and sufficient criteria for the optimal sequence of operations in all cases. While the criteria differ in their specific forms, they all lead to the same principal: those operations with (1) lower yields, (2) lower processing costs, (3) longer lead times, and (4) lower inventory holding costs should be placed higher upstream in the system.Copyright © 2014 Wiley Periodicals, Inc.

US strategic preferences in the early twenty-first century

This article investigates how US national security planners have envisioned the emerging strategic environment during the early twenty-first century and evaluates how their perceptions of this strategic environment have changed during these years. This conceptual evolution can be seen in how defense planners define threats, identify defense priorities, and design security strategies. Five key strategic planning documents serve as the basis for this analysis and illustrate significant shifts in how the US government has envisioned its own security requirements as well as the context within which its strategic vision will need to be realized. These planning documents are: (1) Joint Vision 2020, (2) the Bush Administration's 2002 National Security Strategy of the United States, (3) the Obama Administration's 2010 National Security Strategy, (4) US Strategic Defense Guidance entitled Sustaining US Global Leadership: Priorities for 21^st Century Defense, and (5) the US Chairman of the Joint Chiefs of Staff's Capstone Concept for Joint Operations: Joint Force 2020.
