The general aim of Naval Design (ND) is to make a ship able to perform some prescribed mission. There is a combination of restrictions related to physical interaction of the warship and sea with others that have a military background. As a result, the ND combines numerous tasks and requires tremendous computations, but optimization of computations is a challenge because ND is a multi-criterion problem. This project delivers the complete succession of mathematical fundamentals of ND. Instead of traditional design spiral, a hierarchy multi-level design system is considered. The concept of criterion coordination with Lagrange multipliers is described. The feasible design solutions are studied with the Pareto sets. Comparison of Pruning and Constructive algorithms in grid generation is given, as well as description of LP-tay sequencing in this generation. The developed approaches are illustrated by examples of multidisciplinary ND recently considered in scientific publications. Additionally, a background of multidisciplinary trimaran optimization is developed.
The Engineous Software STTR Team, including team members from Northrop Grumman, Naval Undersea Warfare Center (NUWC), Massachusetts Institute of Technology (MIT), and Elon University; proposed at the outset of the project that it could develop an integrated Multi-disciplinary Optimization (MDO) system of naval ship design and mission effectiveness. Specifically, the team intended to use a ship model of interest to the Navy in an effort to demonstrate that disparate ship analysis tools could be integrated under a single framework and automated. This integrated, automated system would allow its users to measure ship performance and effectiveness, as well as accounting for uncertainty in those measurements, through design exploration techniques, such as optimization, design of experiments (DOE), and quality engineering analysis (e.g. Monte Carlo analysis). The primary struggle on the project was acquiring analysis models to use in the MDO system. The time required to obtain the models, unfortunately, limited the amount of analysis the team was able to perform. However, once the models were obtained, the team was able to quickly integrate them and show the power and flexibility of the MDO system. The results showed that the system was able to quickly apply numerous exploration techniques, including the Multi-Objective Genetic Algorithm specifically developed for the STTR, to the integrated models. Hundreds of ship designs were evaluated in the pursuit of an optimum design; while taking into account uncertainty. A measured improvement of 6% in lifecycle cost was calculated for an optimization analysis. It was also found that while introducing uncertainty in the analysis that the lifecycle cost was perturbed by only a maximum variation of 1%.
This book offers an introduction to the fundamental principles and systematic methodologies employed in computational approaches to ship design. It takes a detailed approach to the description of the problem definition, related theories, mathematical formulation, algorithm selection, and other core design information. Over eight chapters and appendices the book covers the complete process of ship design, from a detailed description of design theories through to cutting-edge applications. Following an introduction to relevant terminology, the first chapters consider ship design equations and models, freeboard calculations, resistance prediction and power estimation. Subsequent chapters cover topics including propeller deign, engine selection, hull form design, structural design and outfitting. The book concludes with two chapters considering operating design and economic factors including construction costs and fuel consumption. The book reflects first-hand experiences in ship design and R&D activities, and incorporates improvements based on feedback received from many industry experts. Examples provided are based on genuine case studies in the field. The comprehensive description of each design stage presented in this book offers guidelines for academics, researchers, students, and industrial manufactures from diverse fields, including ocean engineering and mechanical engineering. From a commercial point of view the book will be of great value to those involved in designing a new vessel or improving an existing ship.

This research advances previous work to create multi-disciplinary design tools that help designers generate innovative conceptual design solutions irrespective of their level of experience. This research builds on existing research including the Functional Basis, a finite set of terms used to define the desired or existing functionality of a product, a Component Naming Taxonomy that is based on a distinct function-based definition, a Design Repository that houses knowledge of existing consumer product designs, and a computational concept generator. The current research develops and tests a system consisting of concept generation, product design and visualization tools (existing and new) with the goal of improving innovation and creativity in engineering design. To enable development of computational tools for product design using the Functional Basis, Component Naming Taxonomy, and Design Repository, the existing database schema of the Design Repository is modified to introduce new terms like the performance type, metric, etc., which are in turn used to define the concept of component interfaces (Input/Output). A modular product design software is then created based on the definition of Interface, which has additional functionality like working directly with the black box function model of the product, and inherently handling branching and merging. The flexibility of the algorithm is demonstrated with a case study. This modular product design software tool is developed using Integer Programming (IP) formulation to solve the design problem using Artificial Intelligence (AI) planning. Finally to enable better understanding of the output from the computational concept generator, the information about the terms in the Component Naming Taxonomy (also needed for the modular product design software) is collected and presented to the users in the form of open source wiki pages.
This open access book gathers the contributions from the Design! OPEN International Conference, held in Parma, Italy in May 2022. The conference explored the multidisciplinary aspects of design starting from its dimensions: objects (design as focused on the object, on its functional and symbolic dimension, and at the same time on the object as a tool for representing cultures), processes (the designer’s self-reflective moment which is focused on the analysis and on the definition of processes in various contexts, spanning innovation, social engagement, reflection on emergencies or forecasting), experiences (design as a theoretical and practical strategy aimed at facilitating experiential interactions among people, people and objects or environments), and narratives (making history, representing through different media, archiving, narrating, and exhibiting design). The contributions, which were selected by means of a rigorous international peer-review process, highlight numerous exciting ideas that will spur novel research directions and foster multidisciplinary collaboration among different specialists.
