Book Description
This thesis explores design options for naval vessels and provides a framework for analyzing their benefit to the Navy. Future demands on Navy warships, such as new or changing missions and capabilities, are unknowns at the time of the ship's design. Therefore, ships often require costly engineering changes throughout their service life. These are expensive both fiscally - because the Navy pays for engineering and installation work - and operationally - because either a warship cannot carry out a desired mission need or is carrying out a mission for which it was not initially designed. One method of addressing uncertainty in capital assets is by imbedding flexibilities in their architecture. The thesis offers early stage design suggestions on flexibilities for naval platforms to incorporate pre-planned repeats of the platform with new or different missions. A conceptual platform created - the SCAMP - includes each of these suggestions in its architecture. Then, the thesis uses an analysis framework similar to real options to evaluate the value of including these expansion options in early stage design versus traditional design methods and their products. The analysis uses a version of the MIT Cost Model for early stage ship design to determine acquisition and life cycle costs. The model was modified to support this analysis by allowing a simulation of possible mission changes with their severity distributed stochastically over a realistic time horizon. Subsequently, the model calculates these effects on life cycle cost. The most important result is the value of the framework for evaluating these managerial options. This framework can be extended to the subsystem level or to the system-of-systems level. In this application, the model predicts that, on average, a flexible platform should not only cost less to build, but also reduce modernization costs by 9% per ship over its life cycle. Therefore, counterintuitively, building a less-capable ship with the flexibility to expand capabilities or switch missions actually provides greater expected utility during its service life.

Book Description
Early stage ship design decisions continue to be a challenge for naval architects and engineers. The complex interactions between the different elements of the ship and the broad spectrum of disciplines required in ship design make it difficult to fully realize the effects and limitations early decisions place on design flexibility. Naval ship design has primarily focused on using point based design methods that do not necessarily produce the most cost effective, innovative, and high quality designs. Recognizing these shortcomings, U.S Navy design is exploring the use of Set Based Design (SBD) principles and methodology in designing the fleet for the 21st century. Existing research has shown the merits of SBD in other industries; however, research on the use of SBD in naval design does not exist. The thesis explores how to execute SBD in light of the recent restructuring of the U.S. Navy acquisition process calling for the use of SBD in pre-preliminary design. This is undertaken using the knowledge gained from exploration of the Ship-to-Shore Connector (SSC) program, the first use of SBD in a new start acquisition program. The thesis concludes by applying the derived information to an early stage submarine concept design. This effort focused on how to develop submarine design parameters and exploration of how to create and reduce integrated concepts.

Book Description
This open access book focuses on both the theory and practice associated with the tools and approaches for decisionmaking in the face of deep uncertainty. It explores approaches and tools supporting the design of strategic plans under deep uncertainty, and their testing in the real world, including barriers and enablers for their use in practice. The book broadens traditional approaches and tools to include the analysis of actors and networks related to the problem at hand. It also shows how lessons learned in the application process can be used to improve the approaches and tools used in the design process. The book offers guidance in identifying and applying appropriate approaches and tools to design plans, as well as advice on implementing these plans in the real world. For decisionmakers and practitioners, the book includes realistic examples and practical guidelines that should help them understand what decisionmaking under deep uncertainty is and how it may be of assistance to them. Decision Making under Deep Uncertainty: From Theory to Practice is divided into four parts. Part I presents five approaches for designing strategic plans under deep uncertainty: Robust Decision Making, Dynamic Adaptive Planning, Dynamic Adaptive Policy Pathways, Info-Gap Decision Theory, and Engineering Options Analysis. Each approach is worked out in terms of its theoretical foundations, methodological steps to follow when using the approach, latest methodological insights, and challenges for improvement. In Part II, applications of each of these approaches are presented. Based on recent case studies, the practical implications of applying each approach are discussed in depth. Part III focuses on using the approaches and tools in real-world contexts, based on insights from real-world cases. Part IV contains conclusions and a synthesis of the lessons that can be drawn for designing, applying, and implementing strategic plans under deep uncertainty, as well as recommendations for future work. The publication of this book has been funded by the Radboud University, the RAND Corporation, Delft University of Technology, and Deltares.

Book Description
The United States Navy is facing a need for a novel surface combatant capability. This new system of ships must be deigned to meet the uncertainty associated with constantly changing required mission capabilities, threats, and technological advances. Flexibility in design and management will enable these systems to maximize their performance under changing conditions. Real options involve the 'right but not the obligation' to take a course of action. Real options embody the flexibility that allows projects to be continually reshaped, as uncertainty becomes resolved. This thesis seeks to identify and analyze the real options available for the design and acquisition of naval ships. This thesis also seeks to determine the value of these options and determine the best types and amount of flexibility to design into naval systems in order to maximize the value of the system over time under uncertain conditions.
