Abstract: ABSTRACT Naval ship design is a complex process involving the integration of many subsystems into a final design which must simultaneously meet cost and effectiveness measures. Alternative ship designs cannot be built and tested due to the cost, effort, and time involved in the design and construction. While scale modeling continues to be widely used in the design process, more computer models are being employed to generate metrics to predict the range of capabilities for alternative ship designs due to the reduced cost of assessing an increased number of concept design alternatives, as well as the improved availability of validated computational tools. Thus in the current acquisition environment, computational tools are necessary to support the design decision making process throughout the product development process. This paper outlines several alternative design philosophy implementations for design decision making: weighted sum, hierarchical weighted sum, analytic hierarchy process (AHP), and multiattribute utility (MAU) analysis. Finally, a quantitative method for cost‐effectiveness trade‐off is presented which can be implemented with any of the four decision making models. A DDG‐51 ship design example is presented using all four methods, as well as for the cost‐effectiveness tradeoff. The characteristics of each method are summarized.
