Dual‐ascent and primal heuristics for production‐assembly‐distribution system design

This article proposes two dual‐ascent algorithms and uses each in combination with a primal drop heuristic embedded within a branch and bound framework to solve the uncapacitated production assembly distribution system (i.e., supply chain) design problem, which is formulated as a mixed integer program. Computational results indicate that one approach, which combines primal drop and dual‐ascent heuristics, can solve instances within reasonable time and prescribes solutions with gaps between the primal and dual solution values that are less than 0.15%, an efficacy suiting it for actual large‐scale applications. © 2012 Wiley Periodicals, Inc.

Thailand and the Insurgency in the South

The insurgency in southern Thailand has proven to be intractable over the last few years. The insurgents, who comprise several different groups, have largely retained the initiative in a series of relatively unsophisticated operations. Although involving ethnic Malay Muslims – and marked by an increasingly strong Islamist ideology – the insurgency has been predominantly ethnic rather than religious. External jihadist involvement has been minimal at best. The recent coup in Thailand may improve the odds of reaching some form of accommodation with the southern insurgents; but it is likely that the south will remain a continuing security problem for Bangkok.     

Insurgency in amber: ethnic opposition groups in Myanmar

Multiple ethnic insurgencies have existed in Myanmar since independence. The military junta's response has been extremely brutal at the tactical level, but has shown some political astuteness at the strategic level, with a series of ceasefires with most of the ethnic groups. Despite these ceasefires – most of which have resulted in the continued existence of quasi-independent armed groups – other ethnic movements have continued their armed operations. The overall strategic picture is one of stalemate, with the ethnic movements continuing to exist, but with few realistic prospects of expanding their operations.     

Countering the effects of IED systems in Afghanistan: an integral approach

The current approach to countering the threat of improvised explosive devices (IEDs) in Afghanistan has met with limited success. The relative lack of success may be in part because the current approach is not holistic and discounts the social systems that foster the IEDs. Insurgents are using IEDs as a tool to further their strategic aims, but the coalition and to a lesser extent the Government of the Islamic Republic of Afghanistan (GIRoA) are attacking the IEDs as if they are an end in and of themselves. Combining network disruption with information change maximizes the opportunities for mitigating the IED threat. More specifically, to mitigate the IED threat requires disrupting the social and economic systems associated with IEDs, and at the same time providing alternative economic opportunities and improving rule of law and governance at the local level. In other words, counter-IED (C-IED) must be Counter-Insurgency (COIN) centric to be successful. This paper reviews the current state of C-IED efforts, identifies five main problems with the current approach, and suggests changes to reduce or mitigate the IED threat in Afghanistan.     

Small states and their armies: Restructuring the militia framework of the Israel defense force

The British provided unprecedented shelter, training and supplies that made possible the revival of a new and better Belgian Army after the crushing German victories in 1940. Starting in Wales in 1940 as a small and disunited group, the Belgians improved more than any of the Allied exile ground forces. By 1944, their independent brigade fought well in Normandy and Belgium, restoring national pride and proving the worth of British help. The parallel and interdependent processes between the British and their Continental guests allows this analysis of the Anglo‐Belgian experience to be useful in considering British Army interactions with the other exiles as well.     

The Insurgency Environment in Northeast India

The northeast states of India have faced a series of insurgencies almost since independence. Most insurgent groups have been based on the competing demands of various ethnic groups, with conflicts not only between the insurgents and the government, but also between groups. The combination of anti-government and intercommunal violence shows little sign of ending. Although the Indian government has made progress in dealing with the largest groups, the continued existence of several dozen insurgent movements represents a significant security threat to internal stability in India.     

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.
