Applying systems thinking towards countering hybrid warfare

Tan, Peihao Raymond. January 2019 (has links)
Thesis: S.M. in Engineering and Management, Massachusetts Institute of Technology, System Design and Management Program, 2019 / Cataloged from PDF version of thesis. / Includes bibliographical references (pages 121-124). / Carl von Clausewitz, a famous Prussian general and military theorist asserted that war's nature of being violent, interactive, and fundamentally political, does not change - only its character does. According to Clausewitz, the character of war is a dynamic phenomenon that manifests differently with the "spirit" of each age. In our current digital age, technology has heavily influenced interactions, including warfare. In addition to boosting traditional military means, technology has enabled rapid and widespread weaponization of social, information and infrastructural instruments for political coercion. A rising trend of combining national instruments of power to wage war simultaneously across the political, military, economic, social, information and infrastructural domains is a rapidly emerging threat, characteristic of modem "hybrid wars" being fought today. Traditional military-centric defense policies and strategies are ill-prepared to address such threats that deliberately operate in the "grey zone", playing on ambiguity and tailoring coercion to remain just below detection and response thresholds. In this research, a combination of literature review, descriptive study, inductive approach, normative research, case study and systems thinking are applied to analyze the hybrid warfare threat and then construct a suitable response framework, treating it as system with interrelated constituent parts, synergistically working together over time, within the wider international context, to deliver an emergent counter hybrid warfare capability. / by Peihao Raymond Tan. / S.M. in Engineering and Management / S.M.inEngineeringandManagement Massachusetts Institute of Technology, System Design and Management Program

Improving the innovation culture within the United States Coast Guard

Chien, Michael P. (Michael Pang-Chieh) January 2018 (has links)
Thesis: S.M. in Engineering and Management, Massachusetts Institute of Technology, System Design and Management Program, 2018. / This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections. / "September 2018." Cataloged from student-submitted PDF version of thesis. / Includes bibliographical references (pages 76-78). / It is increasingly difficult to maintain a technological edge within the United States Coast Guard. Technology continues to advance faster than it can be integrated into the organization. Unfortunately, Federal acquisition requirements and budgetary constraints also contribute to the lack of progress in technology adoption. This thesis explores the current state of innovation within the United States Department of Defense and the United States Coast Guard. In seeking to understand how to improve the culture of innovation within an organization, a review of literature was conducted and applicable key concepts presented. Principles of successful innovation were drawn from a sample of innovation centers within the DoD and Department of Homeland Security, and case studies used to scope innovation within the context of the Coast Guard. Finally, the author includes recommendations to increase innovation within the Coast Guard. This analysis provides a starting point to explore and map the ever-expanding innovation centers within the federal government, specifically in the Department of Defense and the Department of Homeland Security. / by Michael P.

Analysis of Bitcoin as a peer-to-peer network for international payments

Böhme, Sascha January 2014 (has links)
Thesis: S.M. in Engineering and Management, Massachusetts Institute of Technology, Engineering Systems Division, System Design and Management Program, 2014. / Cataloged from PDF version of thesis. / Includes bibliographical references (pages 63-68). / The payment system is due for an overhaul. The antiquated infrastructure that runs the funds transfer network belongs to the pre-Internet era. As a result, international payments are expensive, slow, cumbersome, and not as secure as they could be. This thesis argues that the cryptocurrency Bitcoin is the answer to the problems facing millions of consumers, merchants, and remitters worldwide. The analysis is based on two frameworks. The first one is used to measure how well Bitcoin's attributes meet the needs of the users of the payment system. The second one is used to decide if the payments industry is likely to have one or more dominant platform leaders. / by Sascha Böhme. / S.M. in Engineering and Management

Piper, Victor L. (Victor Lawrence) January 2013 (has links)
Thesis: S.M. in Engineering and Management, Massachusetts Institute of Technology, Engineering Systems Division, System Design and Management Program, 2013. / Cataloged from PDF version of thesis. / Includes bibliographical references (pages 105-108). / Akamai Technologies has achieved market leadership in content delivery and application acceleration services and is pursuing aggressive growth. Akamai has advised the market that growth to $5B by 2020 is achievable by exploiting opportunity within its key markets. However, the internal consensus is that Akamai's legacy business practices are incapable of scaling at the rate of market growth. What must Akamai do to execute on its revenue goals and, more broadly, how can Akamai maintain a leadership position within a dynamic and rapidly expanding market? The goal of this thesis is to discover the elements of Akamai's legacy and emerging growth strategies and to identify strategic options that Akamai may pursue. To gain perspective into evolution of the business and the rationale for current strategic initiatives, a series of interviews with Akamai managers was conducted and a review of an Akamai case study and corporate quarterly earnings was completed. This information yielded insights on the challenges of growth, actions for overcoming these challenges, and motivations for selecting those actions. To gain insight into best practices in growth strategy, a survey of the business strategy literature and case studies of successful technology platform companies was conducted. The literature differentiated between product-based business strategies and platform-based business strategies. Analysis of the differences between these strategies provided insights into Akamai's current challenges. / by Victor L. Piper. / S.M. in Engineering and Management

Modeling and evaluation of aerial layer communications system architectures

Ajemian, Stephen P January 2014 (has links)
Thesis: S.M. in Engineering and Management, Massachusetts Institute of Technology, Engineering Systems Division, System Design and Management Program, 2014. / Cataloged from PDF version of thesis. / Includes bibliographical references (pages 90-91). / Airborne networks are being developed to provide communications services in order to augment space-based and terrestrial communications systems. These airborne networks must provide point to point wireless communications capabilities between aircraft and to ground-based users. Architecting airborne networks requires evaluating the capabilities offered by candidate aircraft to operate at the required altitudes to bridge communications among ground users dispersed over large geographic areas. Decision makers are often faced with choices regarding the type and number of aircraft to utilize in an airborne network to meet information exchange requirements. In addition, the type of radio required to meet user needs may also factor into the architecture evaluation for an airborne network. Aircraft and radio design choices must be made under cost constraints in order to deliver capable communications architectures at an acceptable cost. Evaluating communications architectures is often conducted with modeling and simulation. However, evaluations typically focus on specific network configurations and can become intractable when varying design variables such as aircraft and radio types due to the complexity of the trade space being analyzed. Furthermore, the growth in choices for design variables (such as additional aircraft types) can lead to enormous growth in the number of feasible candidate architectures to analyze. The methodology developed and presented herein describes an approach for evaluating a large number of architecture combinations which vary on aircraft type and radio type for representative airborne networks. The methodology utilizes modeling and simulation to generate wireless communications performance data for candidate aircraft and radio types and enumerates a large trade space through a computational tool. The trade space is then evaluated against a multi-objective decision model to rapidly down-select to a handful of candidate architectures for more detailed analysis. The results of this analysis provide effective tools for reducing the complex trade space to a tractable number of architectures to make an informed architectural decision with no prior articulation of preferences for performance measures. For the notional concept of operation analyzed, the number of feasible architectures was approximately 500,000 for each of the two radio types examined. The decision model implemented reduced the feasible architectures to approximately 50 near-optimal architectures for each radio type. From this manageable set of near-optimal architectures, an analysis is conducted to evaluate marginal benefits versus cost to further reduce the candidate architectures to 3 architectures for each radio type. From these remaining architectures, detailed analysis and visualization can be conducted to aid decision makers in articulating preferences and identifying a single "best" architecture based on mission needs. The enumeration of the trade space using the computational tool and multi-objective decision model is highly flexible to incorporating new constraints and generating new candidate architectures as stakeholder preferences become clearer. The trade space enumeration and decision model can be conducted rapidly to down-select large trade spaces to a tractable number of communications architectures to inform an architectural recommendation. / by Stephen P.

Systems-theoretic process analysis of the Air Force Test Center Safety Management System

Chung, Nicholas, S.M. Massachusetts Institute of Technology January 2014 (has links)
Thesis: S.M. in Engineering and Management, Massachusetts Institute of Technology, Engineering Systems Division, 2014. / Cataloged from PDF version of thesis. / Includes bibliographical references (page 211). / The Air Force Test Center (AFTC) faces new challenges as it continues into the 21st century as the world's leader in developmental flight test. New technologies are becoming ever more sophisticated and less transparent, driving an increase in complexity for tests designed to evaluate them. This shift will place more demands on the AFTC Safety Management System to effectively analyze hazards and preempt the conditions that lead to accidents. In order to determine whether the AFTC Safety Management System is prepared to handle new safety challenges, this thesis applied Dr. Nancy Leveson's Systems-Theoretic Process Analysis (STPA) technique. The safety management system was analyzed and potential safety constraint violations due to systemic factors, unsafe component interactions, as well as component failures were investigated. The analysis identified the key features that make the system effective; gaps in the sub-processes, roles, responsibilities, and tools; and opportunities to improve the system. These findings will provide insights on how the AFTC Safety Management System can be improved with the aim of preventing accidents from occurring during flight test operations. Finally, this thesis demonstrated the effectiveness of the STPA technique at hazard analysis on an organizational process. / by Nicholas Chung. / S.M. in Engineering and Management

Coolhunting and Coolfarming : harnessing the power of collaborative innovation networks using social network analysis / Harnessing the power of collaborative innovation networks using social network analysis

Kulkarni, Rohan A January 2014 (has links)
Thesis: S.M. in Engineering and Management, Massachusetts Institute of Technology, Engineering Systems Division, System Design and Management Program, 2014. / Cataloged from PDF version of thesis. / Includes bibliographical references (pages 71-73). / Email, Instant Messaging, Voice Over IP (VOIP) and other means of online communication have become so ubiquitous today that we rarely take a moment to acknowledge how the internet has changed and redefined the ways in which we communicate and collaborate with fellow human beings. The internet has empowered us to collaborate with others in ways that were not possible till just a few years ago. As we communicate and interact with each other and form relationships, we weave intricate Social Networks that can be analyzed and exhibit communication patterns that can be quantified. In this thesis I have applied Social Network Analysis based techniques that constitute Coolhunting (Gloor & Cooper, 2007) to analyze E-Mail and WebEx communications of sales professionals of a large technology company. I have quantified communication patterns and computed metrics of social network prominence such as degree and betweenness centralities using Condor, a Social Network Analysis and Coolhunting software. Several significant correlations between the success of sales professionals and these quantified communication patterns and centrality measures were found. The communication patterns and centralities of the sales professionals exhibited several traits of Collaborative Innovation Networks or COINs (Gloor, 2006). I have assessed the implications of these communication patterns and correlations and applied the concept of Coolfarming (Gloor, 2011 a) to make recommendations to the technology company on how it could leverage the power of these COINs to their advantage.

Startup founders in high technology

Arbuckle, Phatty (Phatty Judi) January 2015 (has links)
Thesis: S.M. in Engineering and Management, Massachusetts Institute of Technology, Engineering Systems Division, System Design and Management Program, 2015. / Cataloged from PDF version of thesis. / Includes bibliographical references (pages 63-68). / Startup founders are thought to be the super women and men of the technology world these days. Many founders transition into the Chief Executive Officer (CEO) role within their companies and are expected to have the knowledge to lead large organizations through these fast growth and transition periods at a rate much faster than previously encountered in history. While some founders have backgrounds and experience to leverage in order to help them, many do not. Regardless, many high technology founder CEOs are leading companies that grow from nothing into billion dollar valuations and various stages of growth or failure between. This thesis seeks to investigate key traits of high technology founder CEOs, the technologies they create and manage, and research surrounding their transition from founder into the CEO role to include leadership characteristics. An effort will be made to further understand what contributes to a founder CEOs success and based on that recommendations will be given providing some key guidelines. Lastly, example cases will be showcased to highlight how and what founder CEOs have and are doing to create success for not only them, but also their companies, investors, and employees. / by Phatty Arbuckle. / S.M. in Engineering and Management

A systems analysis of the Army Substance Abuse Program

Wadsworth, Christopher S January 2015 (has links)
Thesis: S.M. in Engineering and Management, Massachusetts Institute of Technology, Engineering Systems Division, System Design and Management Program, 2015. / Cataloged from PDF version of thesis. / Includes bibliographical references (pages 104-105). / The Army Substance Abuse Program is a program within the United States Army that has the mission to deter, detect, and treat substance abuse by US Army Soldiers, Civilians, and Family Members. This thesis examines the program from a systems point of view, using the generic US Army installation for the system boundary, and how the system creates value for the installation enterprise. This thesis first explores the motivation for this research, drawing on contemporary reports from the US Army, published news articles, and my own personal experience. Secondly, I examine the system from a systems architecture perspective, employing design structure matrices or adjacency matrices, based on the normative state of the system codified in US Army Regulations. In doing so, I highlight the important architectural changes within the program since 2001 and determine what aspects of the architecture inhibit the program's performance. Thirdly, I examine the system's dynamic behavior over time and establish a causal loop diagram to explain that behavior, drawing on the US Army's reports, the literature surrounding management response to substance abuse in the workplace, and field interviews. I then examine whether commanders are actually adhering to the required processes and if key commander-driven processes are effective in deterring substance abuse. Concluding, I recommend specific actions that can drive more benefit from the program, particularly from the point of view of leader supervision. The research here suggests a degree of architectural dissonance within the program that may limit performance across the US Army. The choices of data capture, access, and authority across organizational boundaries inhibit real-time supervision through command channels and coordination of medical care. Although actions seem to be mostly in compliance with regulations, the rate of non-referrals after positive drug tests is a notable exception. The rate of testing soldiers seems to have the desired impact on behavior while the impact of other commander-driven actions is mixed. / by Christopher S.

Methodology for technology selection for Department of Defense research and development programs / Methodology for technology selection for DoD R&D programs

Nair, Michael L. (Michael Lawrie), 1979- January 2011 (has links)
Thesis (S.M. in Engineering and Management)--Massachusetts Institute of Technology, Engineering Systems Division, System Design and Management Program, 2011. / Cataloged from PDF version of thesis. / Includes bibliographical references (p. 83-86). / In recent years, many of the Department of Defense's major acquisition programs have experienced significant budget overruns and schedule delays. Closer examination of these programs reveals that in many cases, technologies were selected for these programs that did not meet expectations to enable the overall weapons system to achieve its intended goals. A methodology is proposed to extend systems analysis techniques to individual technologies to utilize a rational basis for technology selection. An example of this methodology is shown based on selecting technologies for the US Army's Active Protection System. The example demonstrates that use of this methodology can provide decision makers with a clear understanding of the effects choosing particular technologies. / by Michael L.
