The key to this approach to estimating the effect of seakeeping on mission effectiveness of a feasible design is the application of a model of the mission as a system wherein the functions which perform the mission have the same relationship to each other as the components do in a physical system. Degradation in performance of the mission is calculated in the same manner as reliability of a system made up of separate components. This model is incorporated into the feasibility study stage of the ship design process, and the modified procedure is described. The approach is illustrated by applying it to a monohull example. Functions necessary to perform a given mission and relationships between separate functions were determined. Physical subsystems which perform those functions were selected and substituted into the functional relationship. A regression-based computer ship synthesis program for destroyer-type ships was used to obtain hull form characteristics necessary to create a prototype hull form. A prototype hull was developed using a hull form generation program which uses parametric cubic splines to build a definition of the ship's hull.
