Programmed design of ship forms [PDF]
Computer-Aided Design, 2012 This paper describes a new category of CAD applications devoted to the definition and parameterization of hull forms, called programmed design. Programmed design relies on two prerequisites. The first one is a product model with a variety of types large enough to face the modeling of any type of ship.

A Study into the Validity of the Ship Design Spiral in Early Stage Ship Design [PDF]
Journal of Ship Production and Design, 2016 For many years, the design spiral has been seen to be a convenient model of an acknowledged complex process. It has virtues particularly in recognizing the ship design interactive and, hopefully, converging nature of the process. However, many find it unsatisfactory.
