In the early stages of ship design a considerable amount of experience and knowledge is used to build and evaluate empirical models with known design relationships. However, computer-based systems which aim to assist this stage have tended to concentrate on the analytical aspects of the process and have not been successful in integrating with this expertise and benefitting from it. This paper presents some of the results of a program of research into methods and representing knowledge of empirical numerical relationships used in these early stages of the design process. The work is based on an experimental system, DESIGNER, described in earlier papers. The DESIGNER system is used to carry out a series of evaluations of design sessions, using a warship design model. By examining the progress toward a set of design goals and the classes of interactions used, an improved understanding of the requirements of an interactive numerical design system is developed. As a consequence, methods have been developed to handle approximate values and relationships, to include design margins, and to represent explicitly in the system the definition and use of goals, or design requirements. Using a design model representing a bulk carrier, the paper then presents a worked example to illustrate the use of the new numerical knowledge techniques. It is concluded that the techniques could make a useful contribution to any interactive numerical design system which aims to provide improved use of expertise.

The rapid evolution of the microcomputer has changed the software needs of today's naval architects. The Department of Naval Architecture and Marine Engineering at The University of Michigan has been a leader in the application of computers in ship design education. The computer environment readily available to the department's students has changed dramatically in the past few years with the evolution of the Computer-Aided Marine Design Laboratory within the department and the creation of the Computer Aided Engineering Network (CAEN) within the College of Engineering. The microcomputer facilities available to the students are briefly described. To fully integrate this capability into the department's curriculum, a coordinated suite of computer-aided ship design software has been developed for use on the Macintosh and IBM-PC/XT/AT microcomputers provided for the students. To support the use of this and other software on a wide range of computers, a portable, device-independent computer graphics subprogram package M-PLOT has been developed. The educational philosophy behind this design software and its scope, capabilities, and use in ship design education are described. Examples of the use of selected programs are presented to illustrate these capabilities. Plans for further work are outlined. The effort is well toward the goal of a complete, microcomputer-based ship design software environment.

Abstract The paper presents a method of evaluating the optimal value of the cargo ships deadweight and the coupled optimal value of cargo handling capacity. The method may be useful at the stage of establishing the main owners requirements concerning the ship design parameters as well as for choosing a proper second hand ship for a given transportation task. The deadweight and the capacity are determined on the basis of a selected economic measure of the transport effectiveness of ship – the Required Freight Rate. The mathematical model of the problem is of a deterministic character and the simplifying assumptions are justified for ships operating in the liner trade. The assumptions are so selected that solution of the problem is obtained in analytical closed form. The presented method can be useful for application in the preliminary ship design or in the simulation of pre-investment transportation task studies.
