In the introduction to the IMDC 2015 Design Methodology State of the Art report (Andrews & Erikstad, 2015) it was remarked that that Design Methodology State of the Art report was the first DM Report since IMDC 2009. There had also been a Design for X Report edited by A. Papanikalaou and covering Safety, Performance, Artic Operations and Producability. There had also been a Design for X in 2012, which largely focused on Design for Layout and recent cooperative work by the University of Michigan, Technical University Delft and University College London. It also included an introduction to Design for X (by A. Papanikalaou) and Design for Production (particularly Operations Research in Ship Production Logistics) by F. Dong & D. Singer. There were two other SoA Reports in 2012 covering D for Safety (by D. Vassalos) and LNG Carriers (by A. Murakami & Y. Takaoko).@en

This paper introduces a framework for analyzing distributed ship systems. The increase in interconnected and interdependent systems aboard modern naval vessels has significantly increased their complexity, making them more vulnerable to cascading failures and emergent behavior that arise only once the system is complete and in operation. There is a need for a systematic approach to describe and analyze distributed systems at the conceptual stage for naval vessels. Understanding the relationships between various aspects of these distributed systems is crucial for uninterrupted naval operations and vessel survivability. The framework introduced in this paper decomposes information about an individual system into three views: the physical, logical, and operational architectural representations. These representations describe the spatial and functional relationships of the system, together with their temporal behavior characteristics. This paper defines how these primary architectural representations are used to describe a system, the interrelations between the architectural blocks, and how those blocks fit together. A list of defined terms is presented, and a preliminary set of requirements for specific design tools to model these architectures is discussed. A practical application is introduced to illustrate how the framework can be used to describe the delivery of power to a high energy weapon.
