Abstract—This paper discusses existing military capability models and proposes a comprehensive capability meta-model (CCMM) which unites the existing capability models into an integrated and hierarchical whole. The Zachman Framework for Enterprise Architecture is used as a structure for the CCMM. The CCMM takes into account the abstraction level, the primary area of application, stakeholders, intrinsic process, and life cycle considerations of each existing capability model, and shows how the models relate to each other. The validity of the CCMM was verified through a survey of subject matter experts. The results suggest that the CCMM is of practical value to various capability stakeholders in many ways, such as helping to improve communication between the different capability communities.

Abstract - This paper reviews existing military capability models and the capability life cycle. It proposes a holistic capability life-cycle model (HCLCM) that combines capability systems with related capability models. ISO 15288 standard is used as a framework to construct the HCLCM. The HCLCM also shows how capability models and systems relate to each other throughout the capability life cycle. The main contribution of this paper is conceptual in nature. The model complements the existing, but still evolving, understanding of the military capability life cycle in a holistic and systemic way. The model also increases understanding and facilitates communication among various military capability stakeholders.

Our goal is to get better understanding of different kind of dependencies behind the high-level capability areas. The models are suitable for investigating present state capabilities or future developments of capabilities in the context of technology forecasting. Three levels are necessary for a model describing effects of technologies on military capabilities. These levels are capability areas, systems and technologies. The contribution of this paper is to present one possible model for interdependencies between technologies. Modelling interdependencies between technologies is the last building block in constructing a quantitative model for technological forecasting including necessary levels of abstraction. This study supplements our previous research and as a result we present a model for the whole process of capability modelling. As in our earlier studies, capability is defined as the probability of a successful task or operation or proper functioning of a system. In order to obtain numerical data to demonstrate our model, we conducted a questionnaire to a group of defence technology researchers where interdependencies between seven representative technologies were inquired. Because of a small number of participants in questionnaires and general uncertainties concerning subjective evaluations, only rough conclusions can be made from the numerical results

The political environment of security and defence has changed radically in the Western industrialised world since the Cold War. As a response to these changes, since the beginning of the twenty-first century, most Western countries have adopted a ‘capabilities-based approach’ to developing and operating their armed forces. More responsive and versatile military capabilities must be developed to meet the contemporary challenges. The systems approach is seen as a beneficial means of overcoming traps in resolving complex real -world issues by conventional thinking. The main objectives of this dissertation are to explore and assess the means to enhance the development of military capabilities both in concept development and experimentation (CD&E) and in national defence materiel collaboration issues. This research provides a unique perspective, a systems approach, to the development areas of concern in resolving complex real-world issues. This dissertation seeks to increase the understanding of the military capability concept both as a whole and with in its life cycle. The dissertation follows the generic functionalist systems methodology by Jackson. The methodology applies a comprehensive set of constitutive rules to examine the research objectives. This dissertation makes contribution to current studies about military capability. It presents two interdepen dent conceptual capability models: the comprehensive capability meta-model (CCMM) and the holistic capability life cycle model (HCLCM). These models holistically and systematically complement the existing, but still evolving, understanding of military capability and its life cycle. In addition, this dissertation contributes to the scientific discussion of defence procurement in its broad meaning by introducing the holistic model about the national defence materiel collaboration between the defence forces, defence industry and academia. The model connects the key collaborative mechanisms, which currently work in isolation from each other, and take into consideration the unique needs of each partner. This dissertation contributes empirical evidence regarding the benefits of enterprise architectures (EA) to CD&E. The EA approach may add value to traditional concept development by increasing the clarity, consistency and completeness of the concept. The most important use considered for EA in CD&E is that it enables further utilisation of the concept created in the case project.

Epäherkkien räjähteiden teknologian käyttö mahdollistaa räjähdeturvallisuuden ja sa-malla sotilaallisen suorituskyvyn parantumisen. Suomen Puolustusvoimat päätti IM-teknologian käyttöönotosta vuonna 2004, mikä on edellyttänyt räjähdevalmistajilta tuotteidensa kehitystoimenpiteitä. Yksi osa-alue erään räjähdevalmistajan ajopanostuotteen kehitystyöstä on Exel Oyj:n valmistama panospakkaus, joka pyritään kehittämään uudistuneiden vaatimusten mukaiseksi. Tässä diplomityössä selvitettiin IM-tuotteen vaatimukset ja laadittiin panospakkauksen vaatimusprofiili, jonka perusteella tehtiinkirjallisen selvitys ballistisista materiaaleista. Panospakkauksen rakenneratkaisut perustuivat materiaalinvalintaan, joka toteutettiin ominaisarvovertailulla.Rakenneratkaisuja testattiin sekä ballistisesti että mekaanisilla testausmenetelmillä. Lisäksi testausmenetelmien välille tehtiin korrelaatiovertailuja, joidentulokset ovat lupaavia. Projektin lopputuloksena saatiin kehitettyä Exel Oyj:lle panospakkausratkaisu, jolla voidaan edistää suojattavan tuotteen IM-vaatimusten täyttymistä. Rakenteelle toteutetun lujuusanalyysin perusteella pakkausrakennetta voidaan pitää käyttökohteeseen soveltuvana.

La aparición de las armas nucleares hacia los años ’40 ha cambiado la forma en que ciertos Estados desarrollan sus relaciones bilaterales en materia de seguridad, debido a que la obtención de estas garantiza capacidad militar que no se tiene con las armas de carácter convencional. Tanto Estados Unidos como la Unión Soviética procuraron la producción de las armas nucleares a gran escala, lo cual conllevó a la consolidación de una carrera armamentista entre ambos que fue regulada por tratados bilaterales: esta situación generó un Dilema de Seguridad entre ambos Estados. Con la disolución de la Unión Soviética y el surgimiento de la Federación Rusa en el inicio de la década del ’90, el Sistema Internacional que se había configurado durante la Guerra Fría se alteró debido a que, si bien se había acabado el conflicto que existía en el periodo bipolar, aún existían las armas nucleares con las que se garantizaba la continuación del Dilema de Seguridad que había surgido en los años anteriores. Con la presente monografía pretende analizar el Dilema de Seguridad durante el periodo comprendido entre 1991 y 2010 entre Estados Unidos y la Federación Rusa.

Las relaciones político-militares entre Colombia y Estados Unidos (EE.UU.) se han orientado desde la década de los ochenta a la solución de dos asuntos fundamentales de la agenda bilateral, como son: por un lado, la Lucha contra las Drogas, y desde los ataques del 11 de septiembre de 2001, la Lucha Global contra el Terrorismo Internacional. A partir de esto, la alianza formada entre ambas naciones se ha manifestado, en términos materiales, en el incremento de ayudas económicas, material armamentístico, inteligencia, tropas y contratistas estadounidenses en Colombia, lo cual, acompañado de la alineación colombiana al discurso antiterrorista estadounidense han permitido que Colombia sea considerado por EE.UU. como un aliado estratégico en la región. Ante el escenario de las relaciones colombo-estadounidenses, la administración de Hugo Chávez Frías inició un programa de reorientación de la política de seguridad y defensa venezolana con el fin de garantizar la defensa integral del Estado, a partir del incremento en la adquisición de material bélico y reequipamiento militar, la profundización de las relaciones cívico-militares y el involucramiento directo de la sociedad civil en la defensa del Estado. Por lo anterior, este estudio se centra particularmente, en determinar en qué medida la reorientación de la doctrina de seguridad venezolana durante el gobierno de Chávez, en especial durante el periodo 2006-2010, hace parte de una estrategia defensiva frente a la amenaza identificada en la relación político-militar entre Colombia y Estados Unidos.

The Pax Americana and the grand strategy of hegemony (or “Primacy”) that underpins it may be becoming unsustainable. Particularly in the wake of exhausting wars, the Global Financial Crisis, and the shift of wealth from West to East, it may no longer be possible or prudent for the United States to act as the unipolar sheriff or guardian of a world order. But how viable are the alternatives, and what difficulties will these alternatives entail in their design and execution? This analysis offers a sympathetic but critical analysis of alternative U.S. National Security Strategies of “retrenchment” that critics of American diplomacy offer. In these strategies, the United States would anticipate the coming of a more multipolar world and organize its behavior around the dual principles of “concert” and “balance,” seeking a collaborative relationship with other great powers, while being prepared to counterbalance any hostile aggressor that threatens world order. The proponents of such strategies argue that by scaling back its global military presence and its commitments, the United States can trade prestige for security, shift burdens, and attain a more free hand. To support this theory, they often look to the 19th-century concert of Europe as a model of a successful security regime and to general theories about the natural balancing behavior of states. This monograph examines this precedent and measures its usefulness for contemporary statecraft to identify how great power concerts are sustained and how they break down. The project also applies competing theories to how states might behave if world politics are in transition: Will they balance, bandwagon, or hedge? This demonstrates the multiple possible futures that could shape and be shaped by a new strategy. viii A new strategy based on an acceptance of multipolarity and the limits of power is prudent. There is scope for such a shift. The convergence of several trends—including transnational problems needing collaborative efforts, the military advantages of defenders, the reluctance of states to engage in unbridled competition, and hegemony fatigue among the American people—means that an opportunity exists internationally and at home for a shift to a new strategy. But a Concert-Balance strategy will still need to deal with several potential dilemmas. These include the difficulty of reconciling competitive balancing with cooperative concerts, the limits of balancing without a forward-reaching onshore military capability, possible unanticipated consequences such as a rise in regional power competition or the emergence of blocs (such as a Chinese East Asia or an Iranian Gulf), and the challenge of sustaining domestic political support for a strategy that voluntarily abdicates world leadership. These difficulties can be mitigated, but they must be met with pragmatic and gradual implementation as well as elegant theorizing and the need to avoid swapping one ironclad, doctrinaire grand strategy for another.

Since 1989, NATO has expanded its strategic concept and geopolitical scope to the detriment of an efficient and well-defined military capability in Europe. The Ukrainian crisis has brought the attention back to Europe and to NATO’s deterrent value. As one of the Alliance’s leading members, Britain must act as a catalyst to ensure that NATO has the necessary military strength and political will to respond to the new security challenges.

After the presidential elections on June 14th, the Iranian regime will continue its catch-me-if-you-can game with the international community until it has reached the nuclear threshold. Paradoxically, the key to a solution on the nuclear issue might just lie in discussions on a WMD-free Middle East, but only after Iran has obtained nuclear military capability. At that point, and in the context of a new arms race, both regional and international players may be persuaded that the Middle East has more to gain from negotiations on non-proliferation than from prolonged isolation and the prospect of intractable war.
The capability-affordance model: a method for analysis and modelling of capabilities and affordances
Resumo:
Existing capability models lack qualitative and quantitative means to compare business capabilities. This paper extends previous work and uses affordance theories to consistently model and analyse capabilities. We use the concept of objective and subjective affordances to model capability as a tuple of a set of resource affordance system mechanisms and action paths, dependent on one or more critical affordance factors. We identify an affordance chain of subjective affordances by which affordances work together to enable an action and an affordance path that links action affordances to create a capability system. We define the mechanism and path underlying capability. We show how affordance modelling notation, AMN, can represent affordances comprising a capability. We propose a method to quantitatively and qualitatively compare capabilities using efficiency, effectiveness and quality metrics. The method is demonstrated by a medical example comparing the capability of syringe and needless anaesthetic systems.

Understanding how and why the capability of one set of business resources, its structural arrangements and mechanisms compared to another works can provide competitive advantage in terms of new business processes and product and service development. However, most business models of capability are descriptive and lack formal modelling language to qualitatively and quantifiably compare capabilities, Gibson’s theory of affordance, the potential for action, provides a formal basis for a more robust and quantitative model, but most formal affordance models are complex and abstract and lack support for real-world applications. We aim to understand the ‘how’ and ‘why’ of business capability, by developing a quantitative and qualitative model that underpins earlier work on Capability-Affordance Modelling – CAM. This paper integrates an affordance based capability model and the formalism of Coloured Petri Nets to develop a simulation model. Using the model, we show how capability depends on the space time path of interacting resources, the mechanism of transition and specific critical affordance factors relating to the values of the variables for resources, people and physical objects. We show how the model can identify the capabilities of resources to enable the capability to inject a drug and anaesthetise a patient.

Modelling and simulation studies were carried out at 26 cement clinker grinding circuits including tube mills, air separators and high pressure grinding rolls in 8 plants. The results reported earlier have shown that tube mills can be modelled as several mills in series, and the internal partition in tube mills can be modelled as a screen which must retain coarse particles in the first compartment but not impede the flow of drying air. In this work the modelling has been extended to show that the Tromp curve which describes separator (classifier) performance can be modelled in terms of d(50)(corr), by-pass, the fish hook, and the sharpness of the curve. Also the high pressure grinding rolls model developed at the Julius Kruttschnitt Mineral Research Centre gives satisfactory predictions using a breakage function derived from impact and compressed bed tests. Simulation studies of a full plant incorporating a tube mill, HPGR and separators showed that the models could successfully predict the performance of the another mill working under different conditions. The simulation capability can therefore be used for process optimization and design. (C) 2001 Elsevier Science Ltd. All rights reserved.

This paper applies Pseudo Phase Plane (PPP) and Fractional Calculus (FC) mathematical tools for modeling world economies. A challenging global rivalry among the largest international economies began in the early 1970s, when the post-war prosperity declined. It went on, up to now. If some worrying threatens may exist actually in terms of possible ambitious military aggression, invasion, or hegemony, countries’ PPP relative positions can tell something on the current global peaceful equilibrium. A global political downturn of the USA on global hegemony in favor of Asian partners is possible, but can still be not accomplished in the next decades. If the 1973 oil chock has represented the beginning of a long-run recession, the PPP analysis of the last four decades (1972–2012) does not conclude for other partners’ global dominance (Russian, Brazil, Japan, and Germany) in reaching high degrees of similarity with the most developed world countries. The synergies of the proposed mathematical tools lead to a better understanding of the dynamics underlying world economies and point towards the estimation of future states based on the memory of each time series.
