The objective of this paper is to establish a methodology to evaluate the performance of candidate ship concept designs in the context of mission scenarios. To automate the design evaluation, it is necessary to properly set in an automated way system variables that identify the desired operating point. This is accomplished by defining a constrained static optimization problem. A cost function is minimized...
The Electric Ship Research and Development Consortium (ESRDC) conducted an extensive design exercise using the Smart Ship Systems Design (S3D) tool with the goal of exercising and improving the functionality of the S3D design environment currently under development by the ESRDC. S3D is a design environment that enables concurrent, multi-disciplinary collaboration and that introduces simulation capability...
The Navy's early-stage design tools are integrated with the Leading Edge Architecture for Prototyping Systems (LEAPS) data repository, thus enabling a streamlined, cohesive approach to the creation, storage and access of data pertinent to a ship design. The Smart Ship System Design (S3D) design environment currently under development within the Electric Ship Research and Development Consortium (ESRDC)...
This paper introduces a semi-automated approach to the creation of a detailed design model from an early stage conceptual design, including details of the major software components for such a system, the requirements placed on all participating simulation tools, as well as a formalized process for managing the data in an automated way. The proposed method is compatible with industry-standard simulation...
Recent advances in the sensor and weapons systems being installed on US Navy ships and the electrification required to power them are now forcing the engineering community to re-evaluate the effectiveness of the tools and processes now in use. At the same time, over the last decade there have been significant changes in the way that software is architected and developed. User expectations for software...
The Navy's early-stage ship design tools do not currently include an inherent simulation capability. Under Navy direction, the Electric Ship Research and Development Consortium (ESRDC) has worked to develop a simulation tool that can be used to determine functionality of ship systems at the early stages of design. This paper describes the current capabilities of the simulation tool and the process...
