The concept of utilizing marginal cost factors to determine the overall ship impact of design features is examined. The assumption is made that the design parameters for a feature such as the addition of a piece of equipment can be broken down into requirements for weight, space, manning and electrical power and that these requirements are linearily superimposable. Marginal weight factors in terms of changes in ship displacement were generated utilizing a computerized ship synthesis model. The validity of utilizing marginal weight factors to predict the overall weight impact on a ship was confirmed through a comparison with weight impact predicted directly by the synthesis model. The overall conclusion of the study was that the concept of marginal cost factors is valid for predicting the impact of design changes on naval ships. However, a considerable amount of work remains before the technique can be universally implemented throughout the design community.
