Spaghetti: systems thinking and the US Army

In the mid-2000s, the United States Army was embroiled in counterinsurgency missions in Iraq and Afghanistan that required deeper understanding of local social systems. The Army turned to systems thinking and design thinking to model and understand the world, define problems, and develop approaches to strategic and operational challenges. However, the Army’s approach as expressed in publications and doctrine encourages the development of complicated, unsupported, and unfalsifiable hypotheses. The risk is that the Army will act on incorrect assumptions and develop plans that are fragile.

相控阵雷达LPI搜索方法研究

相控阵雷达可通过合理配置工作参数优化其性能。针对相控阵雷达在搜索目标时易受敌方电子侦察设备威胁的现实,研究了在保持搜索能力的同时,通过合理配置参数降低截获概率的问题。分析了影响相控阵雷达搜索状态LPI(Low Probability of Intercept)性能的主要因素,建立了截获概率模型与搜索能力模型,给出了3种参数调整策略。仿真试验验证了模型的有效性,并比较了3种策略的优劣。     

The case of Donald Rumsfeld: leadership traps in national security

Taking its point of departure in Donald Rumsfeld’s second term as US Secretary of Defense (2001–2006), this article analyses the crisis of strategic leadership in Western national security. Three “traps” are identified that explain why Donald Rumsfeld ultimately was a failure as defence secretary and demonstrate the perils of national security governance. These traps are termed the inquisitor trap, the strong leader trap and the delegation trap. It is argued that our understanding of strategic leadership in national security, particularly in defence, can benefit from insights gained from the study of strategic leadership in business. As such, this article engages the recent trend of merging insights from business and military strategy.
