Value added analysis for army equipment modernization

This paper describes the Value Added Analysis methodology which is used as part of the U.S. Army's Planning, Programming, Budgeting, and Execution System to assist the Army leadership in evaluating and prioritizing competing weapon system alternatives during the process of building the Army budget. The Value Added Analysis concept uses a family of models to estimate an alternative system's contribution to the Army's effectiveness using a multiattribute value hierarchy. A mathematical optimization model is then used to simultaneously determine an alternative's cost‐benefit and to identify an optimal mix of weapon systems for inclusion in the Army budget. © 1999 John Wiley & Sons, Inc.

‘Mad Dog?’ Samuel Huntington and the Vietnam War

Harvard professor Samuel P. Huntington has frequently been considered a Vietnam War hawk. His observation that ‘forced-draft urbanization’ might help the United States win the war has come to define his engagement in contemporary strategic debates. This essay argues that both Huntington’s academic work and his private policy advice to the U.S. Government in fact urged a political settlement to the conflict. It argues that in spite of this, Huntington refused to break publicly with the U.S. policy because of his wider concern over what he saw as a crisis of authority in the U.S. foreign policy and governing institutions in the era.     

Shots per casualty: an indicator of combat efficiency for the first Australian task force in South Vietnam

ABSTRACT

In combat, the ratio of shots fired per casualty inflicted can provide a measure of the combat effectiveness of a force. The shots per casualty ratio achieved by the 1st Australian Task Force in Vietnam is shown to change according to factors including marksmanship, tactics and combat type. While, over the course of the campaign, 1ATF fired an increasing number of shots to achieve a casualty, this is explained by improvements in the quality of Viet Cong and People’s Army small arms. Australian Task Force and US Army shots per casualty ratios are briefly compared..     

Europe's new subregionalism

From the Barents and the Baltic Sea in the north, through Central Europe and the Balkans, to the Black Sea in the south a range of new subregional groups and cooperation processes have emerged in Europe during the 1990s. Compared to NATO and the European Union, these new subregional groups have received little attention. Their ‘indirect approach’ to security, however, plays an important role in overcoming the legacy of the Cold War, reducing the risks of military conflict and addressing non‐military security challenges. As NATO and the EU expand eastwards, subregionalism is assuming growing importance as a means of avoiding new ‘dividing lines’ in Europe. After the wars in Bosnia and Kosovo, subregionalism is also gaining importance as a means of building cooperation in South‐Eastern Europe. The challenge for the future is to give more substance and depth to Europe's new subregional cooperation frameworks.     

Plague and Paradox: Militias in Iraq

Politicians, political pundits, and others focus a lot of attention on the political militias in Iraq, usually blaming them for their destabilising effect on the country and insisting that they disband. This study examines the impact that the militias in Iraq have on the Iraqi government's ability to consolidate control over its territory by first explaining how militias rose to prominence in Iraq during the power vacuum created by Saddam Hussein's ousting, then analysing the many ways militias adversely impact the security situation. The study then examines the other side of the argument – that is, why militias enjoy so much support in Iraq among their constituencies, and why they may actually be necessary to achieve stability in Iraq in the short term.     

An informal survey of multi-echelon inventory theory

Contained herein is an informal nonmathematical survey of research in multi-echelon inventory theory covering published results through 1971. An introductory section defines the term, “multi-echelon,” and establishes the kinds of problems involving multi-echelon considerations. Subsequent sections provide surveys of research on deterministic and stochastic multi-echelon inventory control problems, allocation models, and multi-echelon planning and evaluation models. A final section discusses the present state of the art and suggests directions for future research. A bibliography of papers concerning multi-echelon inventory theory and applications is included.     

A chance-constrained distribution problem

The transportation model with supplies (S_i) and demands (D_i) treated as bounded variables developed by Charnes and Klingman is extended to the case where the S_i and D_i are independently and uniformly distributed random variables. Chance constraints which require that demand at the jth destination will be satisfied with probability at least β_i and that stockout at the ith origin will occur with probability less than α_i are imposed. Conversion of the chance constraints to their linear equivalents results in a transportation problem with one more row and column than the original with some of the new arcs capacitated. The chance-constrained formulation is extended to the transshipment problem.
