A method is developed for determining the optimal policy for entry of customers from many independent classes of Poisson arrivals to a first-come, first-serve (for customers admitted to the queue) single-server queue with exponential service times. The solution technique utilizes a semi-Markov formulation or the decision problem. 相似文献

Many scholars, strategists and pundits contend that the US is in decline. They argue that America's national capabilities are significantly eroding, and that with the rise of important regional powers, its primacy in world affairs is rapidly diminishing as well. Yet America continues to possess significant advantages in critical sectors such as economic size, technology, competitiveness, demography, force size, power projection, military technology, and in the societal capacity to innovate and adapt. This article argues that the nature of material problems has been overstated, and that the US should be able to withstand modest erosion in its relative strength for some time to come without losing its predominant status. Instead, where limits to American primacy do exist, they are as or more likely to be ideational as they are material. The problem inheres as much or more in elite and societal beliefs, policy choices, and political will, as in economic, technological or manpower limitations at home, or the rise of peer competitors abroad. 相似文献

This article examines the concept of ‘shock and awe’ in US military thought. It argues that the term derives from two main sources in defense thinking: rapidity in operations and overwhelming military superiority and is reflected in the concept of ‘full spectrum dominance’. However, the concept is not well attuned to fighting net-based counter insurgency war in a terrain such as Iraq which depends upon both intelligence gathering and adaptive military organizations. The article concludes that US military thinking should be more attuned to the effects of military force especially on political processes and the capacity of insurgents to mobilize popular support. 相似文献

This article examines critically the literature of hybrid war and evaluates the countermeasures often proposed. It explains the concept of hybrid warfare and its varied interpretations, illustrating how it is a manifestation of current anxieties in armed conflict. The selection of the literature is based on works that are referenced, that offer a scientific approach, and which review either the phenomenon of hybrid warfare or its countermeasures empirically. Unscientific works have been omitted. The analysis of the literature presented here shows that the antidotes to ‘hybridity’ lie not in the operational or tactical sphere but in strategic and political domains. 相似文献

This article addresses Western recruitment and management of personnel from non-Western countries in armed forces as part of a strategy of state stabilisation, examining its risks and benefits. ‘SFA’ (Security Forces Assistance) to indigenous forces has long been practised by the West and seems to have returned in recent years in a new form with the creation of armies in Iraq and Afghanistan. However, while providing cheap, proxy substitutes for the West and offering opportunities for state-building, the policy creates its own problems and can have significant, negative consequences. 相似文献

This article examines challenges in international nuclear safeguards pertaining to the timely detection of highly enriched uranium production at large-scale gas centrifuge enrichment plants. To establish where present gas centrifuge enrichment plant safeguards measures and approaches could be strengthened, we have created a discrete time model for simulating hypothetical misuse scenarios, both through transient phases and at steady-state. We find that timely detection of misuse at modern large-scale facilities presents a challenge for international safeguards. A toolbox of unattended measurement systems, along with remote monitoring, however, could be used to improve detection timeliness, enabling the initiation of follow-up activities, potentially on a rapid time scale. These measures, which would need very low false alarm rates, should be implemented in a graded approach, depending on the characteristics of each enrichment plant and an analysis of plausible acquisition paths for the State in which it is situated. Some of these technologies could provide significant benefit to plant operators. 相似文献

AbstractThis paper examines the impact of civil war on military expenditure. We employ two measures of military expenditure: the share of military expenditure in general government expenditure and the logarithm of military expenditures. We would reasonably expect a priori that military expenditure as a share of general government expenditure increases during a civil war and that such increases would taper off over the duration of a civil war. We also explore whether the termination of a civil war induces a decline in the share of military expenditure as a share of the general government expenditure in the short-run. We find evidence the of share of military expenditure increases during a civil war and falls in the year succeeding the end of a civil war, and, in particular, if a war ends in a peace treaty. The level of military expenditures, however, rises during civil wars and does not appear to decline in the short-term after the end of a civil war. 相似文献

In this paper I shift the focus of real exchange rate analysis from conventional macroeconomic variables, which have failed to explain changes in floating real dollar exchange rates, to military security variables, which show an uncanny ability to explain the pattern of floating real exchange rate changes among NATO‐area floating currencies from early 1973 through the failed Soviet coup of August, 1991. 相似文献
