Effective attacks in the salvo combat model: Salvo sizes and quantities of targets

This article considers two related questions of tactics in the context of the salvo model for naval missile combat. For a given set of targets, how many missiles should be fired to produce an effective attack? For a given available salvo size, how many enemy targets should be fired at? In the deterministic version of the model I derive a simple optimality relationship between the number of missiles to fire and the number of targets to engage. In the stochastic model I employ the expected loss inflicted and the probability of enemy elimination as the main performance measures and use these to derive salvo sizes that are in some sense “optimal.” I find that the offensive firepower needed for an effective attack depends not only on a target's total strength but also on the relative balance between its active defensive power and passive staying power. © 2006 Wiley Periodicals, Inc.

Dynamic pricing in a dual‐market environment

This article is concerned with the determination of pricing strategies for a firm that in each period of a finite horizon receives replenishment quantities of a single product which it sells in two markets, for example, a long‐distance market and an on‐site market. The key difference between the two markets is that the long‐distance market provides for a one period delay in demand fulfillment. In contrast, on‐site orders must be filled immediately as the customer is at the physical on‐site location. We model the demands in consecutive periods as independent random variables and their distributions depend on the item's price in accordance with two general stochastic demand functions: additive or multiplicative. The firm uses a single pool of inventory to fulfill demands from both markets. We investigate properties of the structure of the dynamic pricing strategy that maximizes the total expected discounted profit over the finite time horizon, under fixed or controlled replenishment conditions. Further, we provide conditions under which one market may be the preferred outlet to sale over the other. © 2015 Wiley Periodicals, Inc. Naval Research Logistics 62: 531–549, 2015     

Military Maladaptation: Counterinsurgency and the Politics of Failure

Tactical learning is critical to battlefield success, especially in a counterinsurgency. This article tests the existing model of military adaption against a ‘most-likely’ case: the British Army’s counterinsurgency in the Southern Cameroons (1960–61). Despite meeting all preconditions thought to enable adaptation – decentralization, leadership turnover, supportive leadership, poor organizational memory, feedback loops, and a clear threat – the British still failed to adapt. Archival evidence suggests politicians subverted bottom-up adaptation, because winning came at too high a price in terms of Britain’s broader strategic imperatives. Our finding identifies an important gap in the extant adaptation literature: it ignores politics.     

British intelligence and the Soviet atomic bomb, 1945–1950

With relations with the Soviet Union growing ever ‘hotter’, it became essential for the British to comprehend Soviet atomic development. However, British intelligence had to rely on more overt methods of intelligence collection, which provided an inadequate basis from which to proceed. This was further hindered by the interpretation of such information on the basis of Anglo-American development and by the 1946 McMahon Act. Accordingly the first Soviet atomic bomb in August 1949 was not accurately predicted by the British. Meanwhile British war planning centred on the year 1957, based – it was argued – on strategic forecasts. Yet the impact of recently released intelligence material throws this into question, and instead reveals that the date reflected British war readiness, rather than when British intelligence predicted the Soviet Union would have achieved the nuclear capability to wage a successful war.

An Ideological Response to Combating Terrorism – The Singapore Perspective

The article examines alternative strategies to combating the scourge of terrorism beyond military approaches. There is now more realization, especially after the difficulties experienced in Iraq today, that an innovative multi-pronged mix of methods is needed to combat international terrorism. The paper looks at an ideological response towards combating terrorism by looking at the Singapore experience. The Singapore government recognizes the importance of an ideological response as an integral part of counterterrorism measures. Terrorism occurs when opportunity, motivation and capability meet. The prevention of terrorism requires the elimination of at least one of these three factors- motivation- often driven by ideology. The paper will look at direct and indirect initiatives undertaken in Singapore to combat terrorism and will also look at the Muslim community in Singapore's response to the threat to Singapore society. Lastly, the article will examine some lessons learnt from the Singapore experience in applying an ideological approach in combating terrorism as well as some recommendations of what more can be done to move forward.     

The salvo combat model with area fire

This article analyzes versions of the salvo model of missile combat where area fire is used by one or both sides in a battle. Although these models share some properties with the area fire Lanchester model and the aimed fire salvo model, they also display some interesting differences, especially over the course of several salvos. Although the relative size of each force is important with aimed fire, with area fire, it is the absolute size that matters. Similarly, although aimed fire exhibits square law behavior, area fire shows approximately linear behavior. When one side uses area fire and the other uses aimed fire, the model displays a mix of square and linear law behavior. © 2013 Wiley Periodicals, Inc. Naval Research Logistics 60: 652–660, 2013
