Current design procedures often do not optimize the system characteristics (e.g., weight, volume, and cost) of auxiliary systems aboard U.S. Navy combatants. As a result, an automated design process was developed to examine the effect of design changes made to a surface ship auxiliary system on these characteristics. This process will allow comparison of different auxiliary system concepts for the selection of the best system configuration in a given combatant based on weight, volume, and cost impact on the ship. In addition, the design process will uniquely allow the examination of how design changes to an auxiliary system will impact different sized combatants. The automated design process is composed of two main programs -- a Ship Parametric Modeling Program in which the ship and auxiliary system model is developed in a parametric computer program for the NAVSEA CAD-2 system, and a Benefit Analysis Program in which the auxiliary system's characteristics are calculated for comparison to alternative components and system concepts. This report highlights the work done on the automated design process in FY 1993, specifically the work done on the Benefit Analysis Program. A description for use of the automated design process is also given.
