COIN fights: A response to Etzioni

Etzioni both exaggerates and minimizes the influence of my book Learning to Eat Soup with a Knife on different components of US military doctrine, mischaracterizes my treatment of the Malayan Emergency, and unfairly denigrates the successes of counterinsurgency in Iraq from 2007 to 2011 while misattributing the reasons for its failures in both Iraq and Afghanistan.     

On estimating survival for reliability models based on age-related stochastic comparisons

A new class of nonparametric reliability models is introduced and studied. A distribution is said to be better at age s than at age t (sBt) if the residual lifetime at age s is stochastically greater than or equal to the residual lifetime at age t. Applications to various forms of replacement policies, including the cannibalization of failed systems, are noted. For fixed s < t, the problem of estimating a survival curve assumed to belong to the sBt class is addressed using recursive methods. An sBt estimator is derived in closed form, and its uniform strong consistency at an optimal rate of convergence is demonstrated. A simulation study strongly supports the claim that the sBt estimator tends to outperform the empirical survivor function in small- and moderate-size samples. © 1993 John Wiley & Sons, Inc.     

Britain and the chevaline project: The hidden nuclear programme, 1967–82

With the words quoted above, the new Secretary of State for Defence in the Thatcher government revealed for the first time the existence of a project that have remained a closely guarded secret, even from amny Cabinet members of four governments, since the late 1960s. Despite the passage of more thatn 20 years since Mr Pym's announcement, the story of the Chevaline project still remains largely unknown outside a small group of select politicians, officials and scientists. This article sets out to use recently declassified documents and what is in the public domain to tell the story of Chevaline from the secret debates about the need to improve Britain's Polaris deterrent force shortly after it was deployed in the late 1960s to the official announcement of the project in 1980 and its eventual operational deployment in 1982. In particular, attention is focused on three main questions: Why was the project kept secret for so long? Why did the improvement programme take so long to come to fruition? Why, given the spiralling costs involved, was it not cancelled? In order to consider these questions relating to what Pym described as ‘the front end’ of the Poaris missile, it is necessary to begin by looking at the background to the project.     

Index policies for the routing of background jobs

Arriving (generic) jobs may be processed at one of several service stations, but only when no other (dedicated) jobs are waiting there. We consider the problem of how to route these incoming background jobs to make best use of the spare service capacity available at the stations. We develop an approximative approach to Whittle's proposal for restless bandits to obtain an index policy for routing. The indices concerned are increasing and nonlinear in the station workload. A numerical study testifies to the strong performance of the index policies developed. © 2004 Wiley Periodicals, Inc. Naval Research Logistics, 2004     

Properties of an approximate hazard transform

The calculation of the exact reliability of complex systems is a difficult and tedious task. Consequently simple approximating techniques have great practical value. The hazard transform of a system is an invertible transformation of its reliability function which is convenient and useful in both applied and theoretical reliability work. A simple calculus for finding an approximate hazard transform for systems formed by series and parallel combinations of components is extended so that it can be used for any coherent system. The extended calculus is shown to lead to conservative approximations. A first order version of the extended calculus is also discussed. This method of approximation is even more simple to use, but is not always conservative. Examples of its application indicate that it is capable of giving quite accurate results.

US technological collaboration for nonproliferation: key evidence from the Cold War

ABSTRACT

Although the existing international-relations scholarship argues that technological assistance in the nuclear domain increases the probability of nuclear proliferation, the historical account indicates otherwise. Congressional legislation for nonproliferation, economic sanctions, and poor state capacity—specifically, inept managerial capabilities of the recipient state—explain merely part of the puzzle, but overlook the role of positive inducements offered to impede nuclear proliferation. Historical evidence shows that the United States often provided technological assistance with the deliberate intent to inhibit proliferation. In other words, Washington employed its technological leverage to attain nonproliferation goals. American technological preponderance since the end of World War II made such an approach feasible. This study examines key Cold War cases—Israel/Egypt, India, and West Germany—where the United States offered technological assistance with the deliberate intent to stall nuclear proliferation, thereby underscoring the role of assistance for inhibitive ends.     

Stochastically minimizing the makespan in flow shops

In this article, we are concerned with scheduling stochastic jobs in a flowshop with m machines and zero intermediate storage. We assume that there are n - 2 identically distributed and 2 fast stochastic jobs. Roughly, the main result states that the makespan is stochastically minimized by placing one of the fast jobs first and the other last.
