Economic Development and Military Effectiveness

Abstract

What makes some states more militarily powerful than others? A growing body of research suggests that certain ‘non-material’ factors significantly affect a country's ability to translate resources into fighting power. In particular, recent studies claim that democracy, Western culture, high levels of human capital, and amicable civil-military relations enhance military effectiveness. If these studies are correct, then military power is not solely or even primarily determined by material resources, and a large chunk of international relations scholarship has been based on a flawed metric. The major finding of this article, however, suggests that this is not the case. In hundreds of battles between 1898 and 1987, the more economically developed side consistently outfought the poorer side on a soldier-for-soldier basis. This is not surprising. What is surprising is that many of the non-material factors posited to affect military capability seem to be irrelevant: when economic development is taken into account, culture and human capital become insignificant and democracy actually seems to degrade warfighting capability. In short, the conventional military dominance of Western democracies stems from superior economic development, not societal pathologies or political institutions. Therefore, a conception of military power that takes into account both the quantity of a state's resources and its level of economic development provides a sound basis for defense planning and international relations scholarship.     

Dual‐ascent and primal heuristics for production‐assembly‐distribution system design

This article proposes two dual‐ascent algorithms and uses each in combination with a primal drop heuristic embedded within a branch and bound framework to solve the uncapacitated production assembly distribution system (i.e., supply chain) design problem, which is formulated as a mixed integer program. Computational results indicate that one approach, which combines primal drop and dual‐ascent heuristics, can solve instances within reasonable time and prescribes solutions with gaps between the primal and dual solution values that are less than 0.15%, an efficacy suiting it for actual large‐scale applications. © 2012 Wiley Periodicals, Inc.

基于组合赋权雷达图实现电网电能质量综合评估

将改进的组合赋权雷达图方法用于电网电能质量综合评估。对主观、客观赋权法组合,基于组合权重与原权重之间的偏差尽可能小的优化思想,求取雷达图中各项指标的组合权值。利用各指标对应的扇形区域的对角线作为指标轴绘制雷达图,不仅最大限度体现各指标的独立权重,也反映了各指标之间的相互影响。利用雷达图的面积和周长两个变量完成对电能质量的综合评估。最后通过应用实例,验证了论文方法的合理性和在电能质量综合评估中的有效性。
