The Changing Pakistan Army Officer Corps

The Pakistan Army elicits many concerns about terrorism, nuclear and the coherence of the state. However, very little is actually known about this institution. This article mobilizes unique data to address one important facet: the Army's geographical recruitment base. We find that the Pakistan Army has been successful at expanding the geographical recruitment base while some groups (namely those who are native to Sindh) remain highly under-represented. We also find that the officer corps is increasingly coming from urban areas. We conclude with a discussion of the implications of these important shifts subject to the limitations of our data.     

Cyclical schedules for the joint replenishment problem with dynamic demands

The Joint Replenishment Problem (JRP) involves production planning for a family of items. The items have a coordinated cost structure whereby a major setup cost is incurred whenever any item in the family is produced, and an item-specific minor setup cost is incurred whenever that item is produced. This paper investigates the performance of two types of cyclical production schedules for the JRP with dynamic demands over a finite planning horizon. The cyclical schedules considered are: (1) general cyclical schedules—schedules where the number of periods between successive production runs for any item is constant over the planning horizon—and (2) power-of-two schedules—a subset of cyclical schedules for which the number of periods between successive setups must be a power of 2. The paper evaluates the additional cost incurred by requiring schedules to be cyclical, and identifies problem characteristics that have a significant effect on this additional cost. © 1997 John Wiley & Sons, Inc.

A view from Berlin: Colonel Frederick trench and the development of British perceptions of German aggressive intent, 1906–1910

This essay traces the image of Germany that emerges from the reports of Colonel Frederick Trench (1857–1942), British military attache in Berlin from 1906 to 1910. At this time, the British Army possessed only the most limited intelligence‐gathering apparatus and had to rely heavily on the reports of military attaches for information about their continental rivals. Trench, who believed that Germany planned to wage war against Britain and said so categorically in his reports, was the main source of data on the German Army. From the limited surviving records of who read these reports and how they responded to them, this essay posits that Trench's views contributed to the growing British perception of a German threat, a perception that did much to influence British strategic planning in this period.     

Pakistan’s nuclear weapons: how safe is safe enough? Transparency versus opacity

Due to expanding and increasing religious extremism and terrorism coupled with political instability in Pakistan, most western observers believe that Pakistan's nuclear weapons are not secure and could be taken over by terrorists. This would have adverse implications for the region and for global peace, especially for the security of USA and Europe. This article argues that this perception is based on a flawed understanding and knowledge of how Pakistan's command and control setup has evolved and operates. Pakistan's nuclear weapons are as safe as any other state's nuclear weapons. Pakistan has also been active in supporting and participating in global efforts to improve nuclear safety and security. Over the years, Pakistan has been quite open in sharing information regarding how it is improving its command and control system with western governments as well as scholars. This article argues that the steps Pakistan has taken to secure its nuclear weapons are adequate and that Pakistan would continue to further strengthen these measures; however, it is the expanding religious extremism, terrorism and anti-Americanism in the country which make the international perception of Pakistan extremely negative and then seep into the perception of Pakistan's nuclear weapons safety and security.     

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.

New results on a stochastic duel game with each force consisting of heterogeneous units

Two forces engage in a duel, with each force initially consisting of several heterogeneous units. Each unit can be assigned to fire at any opposing unit, but the kill rate depends on the assignment. As the duel proceeds, each force—knowing which units are still alive in real time—decides dynamically how to assign its fire, in order to maximize the probability of wiping out the opposing force before getting wiped out. It has been shown in the literature that an optimal pure strategy exists for this two‐person zero‐sum game, but computing the optimal strategy remained cumbersome because of the game's huge payoff matrix. This article gives an iterative algorithm to compute the optimal strategy without having to enumerate the entire payoff matrix, and offers some insights into the special case, where one force has only one unit. © 2013 Wiley Periodicals, Inc.

Robust ship scheduling with multiple time windows

We present a ship scheduling problem concerned with the pickup and delivery of bulk cargoes within given time windows. As the ports are closed for service at night and during weekends, the wide time windows can be regarded as multiple time windows. Another issue is that the loading/discharging times of cargoes may take several days. This means that a ship will stay idle much of the time in port, and the total time at port will depend on the ship's arrival time. Ship scheduling is associated with uncertainty due to bad weather at sea and unpredictable service times in ports. Our objective is to make robust schedules that are less likely to result in ships staying idle in ports during the weekend, and impose penalty costs for arrivals at risky times (i.e., close to weekends). A set partitioning approach is proposed to solve the problem. The columns correspond to feasible ship schedules that are found a priori. They are generated taking the uncertainty and multiple time windows into account. The computational results show that we can increase the robustness of the schedules at the sacrifice of increased transportation costs. © 2002 Wiley Periodicals, Inc.

Pakistan’s nuclear future: continued dependence on asymmetric escalation

ABSTRACT

In 2019, the geostrategic landscape of South Asia significantly changed. A crisis between India and Pakistan involved air strikes across international boundaries for the first time since the 1971 war. Pakistan came close to economic collapse, while India re-elected hawkish Narendra Modi as prime minister in a landslide. These developments, alongside the United States’ efforts to strike a deal to leave Afghanistan and rapidly improving US-India relations, portend new challenges for Pakistan’s security managers—challenges that nuclear weapons are ill-suited to address. Despite the shifting security and political situation in the region, however, Pakistan’s nuclear posture and doctrine seem unlikely to change. This article explores the roots of Pakistan’s reliance on the traditional predictions of the nuclear revolution, most notably the notion that nuclear-armed states will not go to war with one another, and argues that this reliance on nuclear deterrence is a response both to Pakistan’s security environment and to serious constraints on moving away from nuclear weapons toward an improved conventional force posture. Pakistan’s central problems remain the same as when it first contemplated nuclear weapons: the threat from India, the absence of true allies, a weak state and a weaker economy, and few friends in the international system. While 2019 may have been a turning point for other states in the region, Pakistan is likely to stay the course.     

ANALYSIS OF CONFLICT WITHIN A CONTESTED LAND: THE CASE OF KASHMIR

This paper considers the case of Kashmir to examine the relation between the people of the contested land (Indian-occupied Kashmir) and one of the nation states claiming it (India, in this case) in a game-theoretic framework. The motivation for this paper was whether it was possible to rationalize the lack of democratic space in Kashmir, relative to other states in India (especially since the founding fathers of the country had announced such democratic practices to be the guiding principles of the new nation) and at the same time, a highly rigid stance of the Indian Government on the Kashmir issue. An otherwise standard political economic model is used to capture how the way in which citizens determine their allegiance to one or the other nation state (India or Pakistan) can, in turn, affect the nation state's (India's) policies towards the contested land. I conclude that if the Indian Government perceives allegiance of the citizens to be determined primarily by partisan preferences of the citizens, not so much by their preferences for policies, then the government rationally concentrates on minimizing its disutility due to deviations from its ‘most-favorite' policy. This understanding rationalizes the policies of the Indian Government towards Kashmir. More importantly, it points towards areas that need consideration for any peace-making process to take-off.     

‘Getting COIN’ at the Tactical Level in Afghanistan: Reassessing Counter-Insurgency Adaptation in the British Army

This article reassesses the extent to which the British Army has been able to adapt to the counter-insurgency campaign in Helmand Province, Afghanistan. While adopting Farrell's definition of bottom-up military adaptation, this article contends that the task force/brigade level of analysis adopted by Farrell and Farrell and Gordon has led them to overstate the degree to which innovation arising from processes of bottom-up adaptation has actually ensued. Drawing on lower level tactical unit interviews and other data, this article demonstrates how units have been unable or unwilling to execute non-kinetic population-centric operations due to their lack of understanding of the principles of counter-insurgency warfare.     

Availability of an operating system during a given time interval: A dynamic programming approach

We consider the problem of running a one-unit failure system such that the probability that the system is operating over an entire prespecified time interval (or at least at some time instant during the interval) is maximized. A fixed number of unused units having identically distributed random operating times are at the controller's disposal. Simple assumptions are made on the stochastic failure mechanism. In particular, the time required to activate a unit for the system is supposed to be constant. Analyzing the associated dynamic programming equations yields closed-form solutions. © 1996 John Wiley & Sons, Inc.     

India's Military Instrument: A Doctrine Stillborn

For six years, India has sought to implement an army doctrine for limited war, ‘Cold Start’, intended to enable a Cold War era force optimised for massive offensives to operate under the nuclear threshold. This article asks whether that is presently feasible, and answers in the negative. Doctrinal change has floundered on five sets of obstacles, many of which are politically rooted and deep-seated, thereby leaving the Army unprepared to respond to challenges in the manner envisioned by the doctrine's architects.     

Timely exposure of a secret project: Which activities to monitor?

A defender wants to detect as quickly as possible whether some attacker is secretly conducting a project that could harm the defender. Security services, for example, need to expose a terrorist plot in time to prevent it. The attacker, in turn, schedules his activities so as to remain undiscovered as long as possible. One pressing question for the defender is: which of the project's activities to focus intelligence efforts on? We model the situation as a zero‐sum game, establish that a late‐start schedule defines a dominant attacker strategy, and describe a dynamic program that yields a Nash equilibrium for the zero‐sum game. Through an innovative use of cooperative game theory, we measure the harm reduction thanks to each activity's intelligence effort, obtain insight into what makes intelligence effort more effective, and show how to identify opportunities for further harm reduction. We use a detailed example of a nuclear weapons development project to demonstrate how a careful trade‐off between time and ease of detection can reduce the harm significantly.     

Making long-range planning work: the case of the US Army's 30-year strategic modernization plan

The extensive timespan of evolving assumptions about future adversaries, US military engagements, and technology inherent in the US Army's 30-year modernization strategy can overwhelm the management capacity of planners, and misdirect acquisition investments. Some military scholars have argued that long-range planning is futile due to the complexities of the global security environment. So how can the US Army manage the evolving assumptions inherent in its 30-year modernization strategy to ensure it remains a superior global force? This study will answer the above question by arguing that the US Army's 30-year modernization strategy, while emulative of a similar modernization approach in the threat-based planning environment of the Cold War, is viable if supported by a method and a tool that manage investments and planning assumptions.     

“Respect” as a personal attribute in the British Army

This article describes the results of research into the social phenomenon of “respect” as framed by junior members of the British Army, as part of a wider study into the Values and Standards of the British Army. This research was interview based, using qualitative analysis software to detect, manage, and draw conclusions from the qualitative data recorded in those interviews. The data indicated that the primary situation in which “respect” was visualised by the participants was the unit context, and that it comprised a combination of three different strands: respect for rank or “hierarchical respect,” “professional respect” for a person's military competence, and “personal respect” for an individual's character, personal behaviour, and attributes. The overall respect that an individual is given arises from the combination of these three areas. “Respect” as a concept was, in the soldiers’ characterisation, something that had to be earned (except for the “given” represented by rank) and was not stable: a person's fund of respect could go up or down in social value. Respect was also linked to trust: the more respect a person had, the more they could be trusted. Although the unit context was the primary one for discussing their framing of the concept of respect, many of the participants reported a wider dimension in which every human being deserves a basic level of respect simply for being human, and this level could not be forfeited.     

India's Evolving Nuclear Posture

This article analyzes India's nuclear doctrine, finding it to be critically flawed and inimical to strategic stability in South Asia. In pursuing an ambitious triad of nuclear forces, India is straying from the sensible course it charted after going overtly nuclear in 1998. In doing so, it is exacerbating the triangular nuclear dilemma stemming from India's simultaneous rivalries with China and Pakistan. Strategic instability is compounded by India's pursuit of conventional “proactive strategy options,” which have the potential to lead to uncontrollable nuclear escalation on the subcontinent. New Delhi should reaffirm and redefine its doctrine of minimum credible nuclear deterrence, based on small nuclear forces with sufficient redundancy and diversity to deter a first strike by either China or Pakistan. It should also reinvigorate its nuclear diplomacy and assume a leadership role in the evolving global nuclear weapon regime.     

The procurement problem: An integer programming problem well suited to a solution using duality

A procurement problem, as formulated by Murty [10], is that of determining how many pieces of equipment units of each of m types are to be purchased and how this equipment is to be distributed among n stations so as to maximize profit, subject to a budget constraint. We have considered a generalization of Murty's procurement problem and developed an approach using duality to exploit the special structure of this problem. By using our dual approach on Murty's original problem, we have been able to solve large problems (1840 integer variables) with very modest computational effort. The main feature of our approach is the idea of using the current evaluation of the dual problem to produce a good feasible solution to the primal problem. In turn, the availability of good feasible solutions to the primal makes it possible to use a very simple subgradient algorithm to solve the dual effectively.     

Insurgency in Afghanistan: implications for Pakistan's internal and external security

In the aftermath of 9/11, the USA embarked on a massive global hunt for terrorists and launched its “Operation Enduring Freedom” in Afghanistan. Its failure to control insurgency in Afghanistan spilled over into Pakistan, with disastrous consequences. The resurgence of the Taliban with more formidable tactics and maneuvering skills has become more troublesome for both Afghanistan and Pakistan and for the USA and its allied forces. The fierce comeback of the insurgents has challenged the political and territorial integrity of Pakistan, one that it cannot tolerate. This article analyzes the current situation and its implications for Pakistan's security. Moreover, it looks into the internal and external security complexities that Pakistan faces and the possible implications of the US exit strategy for Pakistan's security. It concludes that the security situation in Pakistan is continuously deteriorating and no part of her territory is immune from terrorists' attacks. To be successful, Pakistan must pursue a broad-based strategy that encompasses military, political, social, economic and informational domains aimed at accomplishing four major objectives: (1) elimination of foreign terrorists and their facilitators; (2) strengthening of the political and administrative institutions in the Federally Administered Tribal Areas (FATA); (3) establishing a safe and secure environment conducive for sustained development and the realization of real socio-economic progress and (4) integrating the FATA into the national mainstream. In the long term, a strategy based on the concept of “Enlightened Moderation” is the right solution, not only to the internal problems of Pakistan but also for the Muslim world and the international community.     

Scheduling patients in an ambulatory surgical center

This paper presents a deterministic approach to schedule patients in an ambulatory surgical center (ASC) such that the number of postanesthesia care unit nurses at the center is minimized. We formulate the patient scheduling problem as new variants of the no‐wait, two‐stage process shop scheduling problem and present computational complexity results for the new scheduling models. Also, we develop a tabu search‐based heuristic algorithm to solve the patient scheduling problem. Our algorithm is shown to be very effective in finding near optimal schedules on a set of real data from a university hospital's ASC. © 2003 Wiley Periodicals, Inc.

Panjwai: a tale of two COINs in Afghanistan

The US Army has two approaches to counterinsurgency operations in Afghanistan. One is hard, or combat-focused, and the other is soft, or development-focused. This study examines two US Army task forces deployed to Panjwai District, Afghanistan from 2012 to 2013. CTF 4-9 and 1-38 offer a meaningful comparison because they pursued these contrasting approaches among the same population and against the same enemy at the same time and place. The study compares each unit’s approach and finds that neither approach was successful absent the other. The article concludes by recommending further research into combining the approaches at the operational level.
