Human Systems Integration Synthesis Model for Ship Design

Abstract

Current fiscal constraints are driving the reduction of system life cycle cost (LCC). A key objective of HSI is the reduction of operational cost and the improvement of operational performance. This thesis seeks to develop a Human Systems Integration (HSI) Synthesis Model for Ship Design. This model is based on the premise that ship design characteristics interact with the domains of HSI. The thesis begins with an historical overview of ship architecture and technology and their interactions with the domains of HSI. The HSI Synthesis Model for Ship Design was developed using the Framework of Naval Postgraduate Schools Systems Engineering Ship Synthesis Model. Quantitative data analysis was conducted using Offshore Patrol Vessel (OPV) design data from Information Handling Services (IHS) Janes database. The data analyzed included 35 ships from 21 nations. Multiple regression analysis consisted of nine independent ship design variables and a response variable of manpower. Data analysis revealed that ship length and ship draught were statistically significant. The proposed HSI Synthesis Model accounted for 49 per cent of the variance of crew complement. This thesis lays the foundation for future qualitative and quantitative analysis of the interaction between ship design characteristics and HSI domains. Additionally, it provides an initial HSI model that can be expanded upon by including additional HSI domains and, ultimately, may lead to a viable design tool for HSI practitioners and systems engineers.
